Abstract

Getrag All Wheel Drive AB (GAWD) in Köping, Sweden today develops,

manufactures and sells All Wheel Drive (AWD) systems to the private car industry.

However it has not always been like this. Before 2004, the very same plant was a

subsidiary company of Volvo Car Corporation, sourcing its need of manual

transmissions and AWD systems. Since now having all car manufacturers as

potential customers GAWD at the same time is affected by the free market

competition from other AWD systems manufacturers. It is now even more important

to be efficient and make operations right the first time, to keep present customers and

also gain new ones.

About the same time as GAWD was formed, it became a member of an international

GETRAG product development process, with a North American car manufacturer as

external customer. It is important to learn from this project since the manners and

customs of the customer are not previously known to GAWD. The purpose of this

master thesis has been to identify structural problem areas as well as making

improvement suggestions regarding quality assurance of GAWD’s product

development. This ha s been achieved by focusing on findings at GAWD and the

expectations of its in-house customer in the United States, GETRAG Axle Plant

(GAP).

After making interviews, observations and a focus group workshop, the problem

areas communication with customer and supplier, involvement in supplier choice

and insufficiently preset prerequisites were identified. The effect has been time

consuming misunderstandings, role ambiguity, lack of motivation and

misinterpretation of some customer expectations.

GAWD is recommended to standardize work within its GETRAG supply chain

members to set target and define scope together, toward optimal GETRAG customer

satisfaction at the lowest use of resources. This can be achieved if day to day work is

based upon strong leadership committed to quality, collaboration, communication

and evaluations among the supply chain companies. The study shows a need for an

early project team kick-off meeting, attended by a cultural agent teaching ways

towards effective collaboration and communication. GAWD should focus on

improving the commitment of the steering team and coordination of communication

among purchasing and project organisations. The later is directly proportional to the

quality of communication with the customer and affects the potential dissatisfaction

the most. GAWD should further assume th at the customer does not know about

Swedish culture or operations until proven otherwise. Organisational changes in line

with thesis result have been made at GAWD during this research process, which is

evidence of continuous improvement activities.

1 Introduction

This chapter contains background information of why the project is of interest to this study

and begins with a description of the problem in focus and is finalized by its purpose,

limitations and definitions.

1.1 Background

Today most countries in the world have in some way been affected by the never

ending global location of production/distribution facilities (referred hereafter as

globalization) and time-based competition. (Bhatnagar & Viswanathan, 2000)

As an example, a driving force of globalization is technological innovation within the

transporting industry (Wild et al. 2003, p. 19), leaving it as less of an argument in

keeping or building production sites at certain places. Instead, other aspects like

labour cost, access to new markets and economies of scale, become more important

in this selection process (Bhatnagar & Viswa nathan, 2000). Apart from the widening

perspective of businesses that globalization contributes to, outsourcing and focusing

on core competence has been dominant orders from chief executive officers in the

past decade. This has led to the emergence of borderless organizations with globally

located suppliers and production/distribution facilities, in order to stay effective and

competitive in the free market. Perhaps the phenomenon has been especially obvious

in the manufacturing business, where Asia, and China in particular, has risen

becoming a large supplier of goods and services. Strongest contributors to this

emerge is the continents low cost of labor and raw material. With globalization

comes an increased need of cultural knowledge of people in general and of the

international business environment in particular. This information is crucial in order

to understand and interpret messages from customers and suppliers correctly

(Robbins, 2003), who might geographically be located hours - or even days - of flying

away.

The end consumers have in the past years changed its demand pattern towards

wanting a wider variety of products to minimal lead time. According to Bhatnagar &

Viswanathan (2000) th is trend is likely to intensify in the future as companies adopt

mass customization, leading to greater choice for customers.

The automotive industry has in the latest years been forced to cut its time of

developing new models by more than half, hence the even higher obligation today of

making it right the first time.

GETRAG All Wheel Drive AB (GAWD) in Köping, Sweden was created as a

partnership among the German/American companies GETRAG/DANA and

Swedish Volvo Cars Corporation (VCC), in January of 2004. Before this, the Köping

plant was a wholly owned subsidiary of VCC, and manufactured manual

transmissions since 1927. Since the start of GAWD in 2004, the manufacturing and

assembly of manual transmissions has moved to Cologne, Germany where FORD

Motor Company wants to coordinate gearbox manufacturing in order to maximize




synergy effects. GAWD is instead focusing on becoming a centre of excellence in All

Wheel Drive (AWD) systems. (External press material GAWD, 2004) All car

manufacturers in the world are now becoming potential customers. Competition is a

consequence since it now operates in a free market compared to former in-house

VCC component supplier. The owner parties have since the birth of GAWD, enforced

a claim of further extended process effectiveness in order to move towards a globally competitive AWD Center of Excellence. According to Norestig (2006) it is an absolute

condition to enter the Asian market in order to get lower supplier costs and thereby

have the ability to submit competitive quotations.

1.2 Problem

Theta is a vehicle project name from a worldwide operating car manufacturer. The

group parent of GETRAG got the contract to supply AWD-systems to Theta. An in-

house supply chain was set up, Figure 1-1, where GAWD is right now supplying

three vital parts to its customer GETRAG Axle Plant (GAP) in the US. GAP does the

final assembly of the complete AWD system before it is dispatched to the car manufacturer. An Indian based engine and transmission component manufacturer

source GAWD with pre-machined shafts, which are the basis component of two of

the three vital parts previously mentioned. Within the supply chain is also GETRAG

Engineering Center (GEC) in Detroit, who designs the complete AWD system.

Figure 1-1: Principal outline of Theta AWD project supply chain

Before the birth of GAWD, VCC was the only customer and geographically held

within Sweden and Belgium. VCC is still a customer but not in the Theta project,

where both a major supplier and the customer are from outside Europe. Both the

Theta supplier and customer have different corporate cultures than GAWD, apart

from the obvious, speaking a different language. This is a new situation for the

project management team at GAWD, but something it needs to adopt, in order to

stay competitive in the industry.

Alongside new products in this industry comes documentation in order to assure a

high product quality level before entering regular production. This process is

summarised as the Product Part Approval Process (PPAP). GAW D have used this

product quality assurance procedure in previous projects, but in Theta it is more time

consuming.




1.3 Purpose

The purpose of this master thesis is to identify structural problem areas as well as

improvement suggestions in the quality assurance of Theta project at GETRAG All

Wheel Drive AB.

1.4 Delimitations

The research study will be limited to potential structural improvements indicated by

the three GETRAG companies GAWD, GAP and GEC only. These three companies

control the main activities in the manufacturing of Theta PTU and are therefore most

interesting to the specific study. The recommended improvements will further not be

implemented within th e frame of this study, since estimated too time consuming.

When analysing problem areas in the Theta project, other aspects of improvement

actions will be considered, however quality assurance improvements will be in focus.

1.5 Definitions

Since mentioning the three different GETRAG companies many times in this thesis,

they will be called GAWD, GAP and GEC when used.

When the author addresses customer in this report, the interpretation should be

GAP. The car manufacturer when addressed is called external customer and buyer of

an AWD car, end user. A second confusion among the customer name GAP is it

being the same as the model developed by Zeithaml et al. (1990) explaining

dissatisfaction. The distinction among them is GAP [customer] and Gap [model by

Zeithaml et al., 1990].

The word project when used is referring to one execution of the product

development process having a specific customer. GAWD has several projects

running at the same time.




2 Company Description

This chapter presents overall description of Getrag All Wheel Drive AB as a company, its

owner parties and selection of products.

2.1 History

In the year 1826, Köpings Mekaniska Verkstad (KMV) was established in Köping,

Sweden. Main activity at this time was manufacturing of various components to

surrounding industries, unti l 1927 when KMV started gearbox production for Volvo.

KMV did so for fifteen years before it was bought by Volvo, becoming a subsidiary.

Eventually the business expanded to producing gearboxes, rear axles and assembling

of spring struts. In the middle of 1990’s, production of AWD systems was added to

that list. At the same time as starting this additional production, VCC began examine

the possibility of attracting an external partner to the plant. That was in purpose to

generate supplementary stimulation of business development. Volvo Cars was

bought by Ford Motor Company (FMC) in 1999, and the previous negotiations of

finding a strategic partner to the plant in Köping continued. (Guide presentation,

2006)

The new company emerged in January of 2004, as VCC finally did outsource its

transmission, chassis and AWD operations. A holding company among German

GETRAG and American DANA Corporation bought sixty percent of the shares in the

new company and became major owner. Volvo now made investment funds

available. The rest forty percent is yet to this date owned by Volvo Cars Corporation,

see Figure 2-1 for legal structure. (GAWD External Press material, 2006)

GETRAG Group is privately owned and based in Untergruppenbach, Germany. The

company was founded in 1935 by Mr. Hermann Hagenmayer and has today sixteen

factories worldwide manufacturing manual transmissions to regular cars, SUV’s,

motorcycles, and light trucks. (Guide presentation, 2006)

According to GETRAG website (2006), GETRAG Corporate Group is a systems

supplier and integration partner for transmission and drive train systems, delivering

an annual volume of more than three million transmissions and one million axles.

Further is GETRAG Corporate Group the largest independent manufacturer of

transmissions in the world (GETRAG Website, 2006).




DANA Corporation is, according to DANA Corporate website (2006), leading

supplier of drive train, chassis, structural, and engine technologies. They design and

manufacture products for every major vehicle and engine producer in the world.

DANA is focused on being an essential partner to automotive, commercial, and off-

highway vehicle customers. (DANA Corporate website, 2006)

VCC has, according to its corporate website (2006), factories in Gent, Gothenburg,

Skövde, Olofström and Floby. VCC is still to this date the largest AWD customer to

GAWD. It’s provided car models S40, V50, S60, S80 and XC90 a ll have the AWD

option.

At the same time as the creation of GAWD, the factory became member of the

GETRAG Corporate Group network of sites, seen in Figure 2-2. This opens new

possibilities of economies of scale, and at the same time abilities of reaching new

markets.

Figure 2-2: GETRAG Group wor ld sites (GAWD Guide presentation,

2006)

After a major reformation of manual transmissions to GETRAG-FORD Transmission

(GFT) in Cologne, GAWD now focuses of becoming an AWD center of excellence

(External Press material, 2006). That has included building fully functional sales,

purchasing, and product development departments in the last couple of years.

2.2 Products

In this part, the produced products are further explained, but before introducing any

specific details, the general function of an AWD-system needs to be further

explained.




The functional outlines of the AWD-system can be seen in Figure 2-3. According to

GAWD Internal Training material (2006), the Power Take-Off Unit (PTU) is mounted

on to the gearbox, having the front axle shaft through its center. The PTU increases

the rpm from the gearbox, transferring torque, via the drive shaft, to the Active on

Demand Coupling (AOC) further back. According to Internal Training material

(2006) the AOC manages distribution of torque among rear and front wheels, which

is not constant. Finally, the Rear Drive Unit (RDU) decreases the rpm and

simultaneously makes the rear axle shaft run (Internal Training material, 2006).

In this way all four wheels can be involved in driving the car, hence the name AWD.

Normally, the car using this AWD-system is front wheel driven. If any of the front

wheels indicate a spinning manner, the rear wheels immediately are distributed

torque by the AOC. The same process occurs if the two left wheels are starting to

spin, then the right wheels get all engine torque instead. The car is driving as long as

at least one wheel has surface grip. (Internal Training material, 2006).

PTU

RDU AOC

Figure 2-3: Principal outline of an AWD-system (Internal Training

material, 2006)

GAWD is part of GETRAG drive train system manufacturing. Its core competence is

production of both PTU: s and RDU: s, explained above. Vital parts as input shaft,

pinion, ring gear, housings and flanges are manufactured and assembled together

with supplier material. The AOC-unit is consequently bought from supplier with no

further machining before assembly. At present, GAWD have several different such

customer projects, to a total annual volume of about 250,000 systems. The two

products are more detailed pictured in Figure 2-4 and Figure 2-5, below.

Take-off Unit (right).

3 Method

This chapter presents the method used and its different elements during the study. Research

strategy and process of work will be presented in the beginning and finally the chapter is

ended with a discussion of validity and reliability.

The choice of method can, according to Lekvall & Wahlbin (2001, p. 209), be divided

into two different dimensions, [1] Research Strategy and [2] Data collection. The two

method dimensions will first be presented separately and later summarized.

3.1 Research strategy

A distinct research strategy is essential to know how to design the method.

According to Yin (2003, p. 3), the research strategy is the way of collecting and

analyzing empirical evidence. Lekvall & Wahlbin (2001, p. 209) defines it as the

technique used to make conclusions from a study . 1

Yin (2003, p. 5) further suggests three topics one should consider in this dimension,

see Figure 3-1. According to Yin (2003, p. 5) the different strategic alternatives are

Experiment, Survey, Archival analysis, History and Case study.

Figure 3-1: Three topics to consider when choosing research strategy (Yin, 2003)

The general setting of this study has already been set by GETRAG; hence the author

has no possibility of controll ing all behavioural events ending up showing a specific

result. Experiment can then be ruled out as research strategy. A wide mindset has to

be in use but to a limited system – GAWD and its customer. Survey can then be ruled

out as strategy since it is a cross section study focusing on contrasts among

respondents within a specific population (Lekwall & Wahlbin, 2001, p. 204). Yin

(2003) proposes both Archival analysis and History strategies to be suitable when

studying one or several cases focusing at its development over time. The thesis

purpose is to define problems in an ongoing product developing process. Problems

might have occurred at different times, but time as a factor is of no interest to this

study, hence both of the two research strategies Archival and History can be ruled

out.

Yin (2003, p. 8) proposes the case study’s unique strength to be its ability to deal with

a full variety of evidence - documents, artefacts, interviews, and observations.

Further that Case study has a distinct advantage when a ―how‖ or ―why‖ question is

being asked about a set of contemporary set of events, over which the investigator

Lekvall & Wahlbin (2001) is translated and interpreted from Swedish by the author 1

S Saravanan (Roll no: PG/327/ EMBA/2008D) - International product development in automotive industry - 20-12-2010



S.Saravanan (Roll no: PG/327/ EMBA/2008D) International product development in automotive industry 20 12 2010

has little or no control (ibid). These two statements strengthen the suitability of

choosing Case study as research strategy, since studying problem areas occurred

within GAWD Product development requires identification of how and why they

emerged and later how they can be eliminated. This work need to be based on

different sources of evidences in order to obtain a holistic examination.

The author had in the summer of 2006 opportunity to work as resident engineer

located at GAP in the United States. Resident engineer meant in this position being

contact person between the two different business cultures and language residents

which GAP and GAWD represent. That at the same time implies being member of

the Theta project team and as far as research strategy is concerned, regarded as

action research.

Dick (1991) defines action research as a family of research methodologies which

pursue action or change and research at the same time. Participants in action research

contribute equally to the inquiry, and the researcher is not an external expert

conducting research, but a partner working with and for those affected by the

problem, according to Altrichter et al. (2002). This part has in the research strategy

played a minor part, but still needs to be considered and has been in the authors

mind during the whole study.

3.2 Data collection

The second dimension regards type of data used. Lekvall & Wahlbin (2001) separates

among qualitative/quantitative respectively primary/secondary data. The two types

of data are further explained below.

3.2.1 Quantitative and Qualitative data

According to Lekvall & Wahlbin (2001, p. 213) the distinction among qualitative and

quantitative data is (1) the way of expressing the data to the coming analysis: coded as

figures or expressed as words or pictures and (2) if the type of research strategy

chosen in dimension one is statistical or based on verbal reasoning and mind maps . 1

The quantitative collection of data is often statistical and based on figures. An

example is figures from a business system, which can be seen as quantitative.

Silverman (2001) describes that a qualitative study may be analysed from

information collected from interviews, observations, text or documents and sound or

picture recordings.

GAWD wants the author to describe and analyse the problems facing project team in

Theta. This has been mainly obtained through interviewing Theta member personnel

at GAP and GAWD, which is qualitative to its nature according to Silverman (2001).

Some quantitative data such as figures have also been collected, but to a much less

extent, hence an emphasising qualitative approach.

3.2.2 Primary and Secondary data

According to Lekvall & Wahlbin (2001) it is important to separate among primary

and secondary data. Primary data is data that you collect by yourself. It could be




( / / / ) p p y

counting non-conforming parts in a box, or conducting personal interviews.

Secondary data has been collected by someone else earlier in a different purpose,

according to Lekvall & Wahlbin (2001).

Advantages of collecting primary data, has, according to Lekvall & Wahlbin (2001, p.

250), first to be divided into two categories; [1] observations or [2] interviews. If

collecting primary data from observations, Lekvall & Wahlbin (2001) proposes that

courses of events can close to a complete certainty be registered. A pitfall is primary

data being limited to study present courses of events connected to behaviours. If

using interviews when collecting primary data, past, present or anticipated pieces of

information are possible to collect, yet limited to remembrance, knowledge or the

willingness of the respondent to answer (Lekvall & Wahlbin, 2001).

Secondary data collection has the advantage as being a time efficient way of

obtaining data. A disadvantage may conversely be the difficulty in estimating quality

and applicabili ty of the secondary data, according to Lekvall & Wahlbin (2001), since

not been suited after your particular problem of interest.

This study is made mostly by collecting primary data by interviews and focus

groups, and the secondary data used is mainly collected from databases at GAWD.

The two dimensions discussed above in sections 3.1 and 3.2 can, if separating among

data collection methods, all together be explained by Figure 3-2. The level of

darkness of the cubes indicates which specific combination used in this thesis. The

darker the cubes are, the more significance to the study. Recall from section 3.1 that

case study has a little influence of action research, not indicated in Figure 3-2 however.

Figure 3-2: Classifying method of study

3.3 Process of work

It is of importance to embark upon problems systematically and accurately when

looking for assignable causes of variation. One way of achieving this is by using the

improvement cycle invented by Deming W.E (1986) under influence by Walter A.

Shewhart. It is known as the Plan – Do – Study – Act or simply the PDSA-cycle. The

construction of this paper follows the process presented in Figure 3-3. The PDSA-

cycle is used to create structure to work and thereby gain of research quality.

Figure 3-3: The thesis process interpreted as components in the PDSA

cycle by Deming W.E (1986).

The PDSA cycle is, as seen above, separated into four different parts. Plan, do, study

and act. The different parts are explained in more detail in the following sections.

3.3.1 Plan

When problems are detected, first thing to do is to establish the principal causes of

the problem (Bergman & Klefsjö, 2003 p. 212). Further proposed by Bergman &

Klefsjö (2003), large problems need to be broken down into smaller manageable ones

and systematically advance towards root cause. Since the righteousness of the thesis

results is depending on the preparations made, it is critical that this process is not

rushed through. See a detailed mapping of the planning process in Figure 3-4.

Figure 3-4: Activities in the Planning process

Determination of problem ba ckground and deciding of thesis purpose, is at first

developed together with quality and projects department at GAWD. Title and

purpose was set after useful consulting of my supervisor, Karin Schön at Luleå

University of Technology. The chapter Theoretical frame of references is compiled

after literature studies in academic quality management books and articles.

Influences are taken from course literature in earlier courses, librarians and fellow

students. It all began however by examine former master’s theses at the division of

quality and environmental management at Luleå University of Technology. Further

searching of references was made by the keywords Outsourcing, Globalization,




Communication, TQM, Deming, Project management, Asia, Cultural differences and

Customer satisfaction. The databases used are in no particular order, LUCIA, LIBRIS,

Emerald Insight, and Book-It, see chapter 9 References for internet addresses. A great

amount of books and articles were at first collected and the most relevant theories

and topics finally chosen to represent the outer frame of the research. This method of

gathering a large amount of literature in the beginning was primarily chosen because

of far distance to closest university library, serving quality management. The risk of

not having a certain source of information at time needed could then be eliminated.

Process mapping

Most organised activities can be regarded as a process, defined by Bergman & Klefsjö

(2003) as ―a set of interrelated activities that are repeated over time‖. Sandholm

(2000) further explains that a way to obtain a clear picture of how the tasks a process

involves are performed is to use a flow chart. This illustrates graphically the steps

which lead to the goods or services, and provides a better understanding of the

process as a whole. This method has been used mainly when identifying Theta

project in chapter 5.2 Theta.

The Seven Management Tools

Since verbal and qualitative information is to be collected according to the research

method chosen in Figure 3-2, Klefsjö et al. (1999, p. 15) suggest to use one or more of

the Seven Management Tools to identify and create a common picture of the

problem. The Seven Management Tools are primarily compiled to handle

unstructured verbal information (Bergman & Klefsjö, 2003) and can be seen in Figure

3-5.

Figure 3-5: The Seven Management Tools (Bergman, B. & Klefsjö, B.

2003)

The intention of the Seven Management Tools is, according to Klefsjö et al. (1999), to

identify and create a comprehensive view of the businesses different problems.

Greatest use of the above tools is achieved if they are used in combination or in

sequences. By using them in sequence creates a systematic procedure of sorting not

previously structured verbal information. It may also be used to identify underlying

problems and coming solutions.

Out of the members of the Seven Management Tools, one has been particularly

useful in creating structure to my work in the planning process of this thesis, seen in

Figure 3-4. This is the Tree Diagram and is briefly explained on next page.



3.3.2 Do

An improvement team is in this phase, according to Bergman & Klefsjö (2003, p. 213),

given the task of carrying through the suitable steps in solving an important cause of

a problem. A key significance in this work is making everyone concerned aware of

the problem as well as improvement steps. (Bergman & Klefsjö, 2003, p. 213)

This corresponds to core empirical data collection in the thesis process, Figure 3-3.

The improvement steps can be seen as the actual collection of qualitative and little

extent of quantitative data, more detailed as the answers to question [2] in Figure 3-6,

now specified in Figure 3-7 below.

Figure 3 -7: Activities in the Do process

First step is to collect knowledge of project activities in general. That includes

explorative interviewing GAWD Project Leader and collecting data from internal

databases. Next step in the Do-phase was to define problem areas arisen in Theta,

regarding structure such as organizational and/or communicational topics. Further

was the perception of the customer examined.

Interviews

An interview can be described as teamwork among two people with different and

non-paired roles. One is asking the other one is answering. This teamwork is based

on free will and it is th e communication among the two, which is target for analysis.

The interview can be separated from talking by; the interview is issued to collect

information only, and the interviewer has a purpose by doing the questioning. The

interviewer and the respondent have different tasks, where the responsibility of the

situation and its accomplishment lies in the hands of the interviewer. The interviewer

searches for information about something (not everything) and this delimitation decides what is to be said. (Lantz, A. 1993)

There are different types of interviews. The most common difference among them is

the level of structure. An interview can be open, meaning that the interviewer is

asking a wide, open question which the interviewee freely develops his or her mind

about. In the other end of structural level is where the interviewee is asked specific

questions with a multiple choice answering type, in a pre set order. (ibid)

Lekvall & Wahlbin (2001) classifies the interview methods explained by Lantz (1993)

as being personal interview, telephone interview, internet inquiry and inquiry,




sorted in order of structural level from low to high. Lantz (1993 p. 21) means that out

of these interview methods, only the two first can be used when collecting qualitative

data. This is why only those two interview methods will be further explained.

Personal interviews

The advantage of conducting a personal interview is by Lekvall & Wahlbin (2001) the

close to unlimited ability of asking different kinds of questions. This includes

showing pictures or other illustrations while questioning. The drawbacks on the

other hand are that it is time consuming and can be very expensive (ibid). Especially

if the interviewer travels to its respondents, who might be situated world wide.

All employees at GAWD are situated within the same factory complex in Köping.

This circumstance makes personal interviews easy to organise. Together with

supervisor at GAWD were decided that the advantage of making personal

interviews at GAP outweigh the alternative, telephone interviews. The travel to the

US is expensive, but could be combined with other professional purposes, which

lowered the specific interview expense. However when being in the US, it is still

expensive to travel domestically. That together with the low number of respondents

at the GEC facility, left telephone interview as only choice.

One and a half hour interviewing time was scheduled with every single respondent.

An email containing purpose and other background information was sent in advance

to the chosen informants. An interview guide was used at all times making sure not

leaving any question behind, see Appendix 2.

Telephone Interviews

The advantages of conducting telephone interviews instead of personal interviews

are that it is exceptionally cheaper and relatively fast. The main disadvantage is the

restriction in interview time. Lekvall & Wahlbin (2001 p. 266) describes that a

telephone interview normally can last for five to thirty minutes depending on the

respondents interest in the research field. The respondent at GEC is fully involved in

the topics asked and therefore also assumed to be interested in improving current

situation.

Observations

Observations mean that the researcher with his or her own eyes records specific

courses of events that are of interest to the research. The advantage of using this data

collection method is according to Lekvall & Wahlbin (2001 p. 257) that events can be

registered at full security and not depend on other peoples knowledge, remembrance

or willingness of talking. Observations have been made by the author at both GAP

and GAWD, however since at the time being member of Theta project it is at the

same time regarded at action research, explained in section 3.1.




3.3.3 Study

Bergman & Klefsjö (2003, p. 214) proposes to investigate the results in the Study

phase of the PDSA-cycle. This is to see if the implementing of the improvement,

earlier conducted, was in fact successful, according to Bergman & Klefsjö (2003, p.

214)

The collected empirical data in the Do phase is, in Study, processed compared to

reference theories presented in chapter 4. Since both Plan and Do a re systematically

done, Study also becomes methodical to its nature. After prioritizing among

improvement actions, final recommendations are given. A detailed picture of the

Study process is seen in Figure 3-8 below.

Figure 3-8: Activities in the Study process

Analysis

According to Patton (1990, pp. 371-372), the challenge is to make sense of large

amounts of data, reducing it’s volume, identify patterns and communicate the real

meaning of the data. Each qualitative study will be unique; therefore, the analysis

approach will also become unique (Patton 1990, p 372). According to Guba (1978) the

researcher must deal with the problem of convergence when analysing data.

Convergence is the problem of figuring out what data that fit together, according to

Patton (1990). Patton (1990) further suggests the human factor to be the strength and

at the same time, the fundamental weakness of qualitative analysis.

The patterns of the empirical data were organised by putting answers to each

question of the interview guide together. This work rendered the affinity diagram

seen in appendix 4 and more detailed presented in chapter 5. The reducing of its

volume was made by the respondent team when putting votes to the same affinity

diagram, which are analysed using chapter 4 as reference.

3.3.4 Act

Bergman & Klefsjö (2003, p. 214) proposes the act phase to correspond to learning

and gaining experience from the previous steps taken in order to avoid ending up

with the same problem in the future.

The act, or realisation phase of this thesis, will have to be up to GAWD to decide. The

author however sees this thesis corresponding to the Plan-phase of a larger cycle of

PDSA. Next step could be to implement all or parts of the conclusions and




recommendations given in chapter 7 which then corresponds to a Do-phase. This

relation is illustrated by Figure 3-9, where the Thesis PDSA cycle rotates upward a

rising line symbolised by higher customer satisfaction. It pulls product development

at GAWD upwards the ladder of higher customer satisfaction. Future analysis and

feedback is necessary to verify improvements made.

Figure 3-9: Thesis process in relation to GAWD product development

quality improvements

3.4 Validity & Reliability

Reliability is a measure of how reliable the data in study is (Johannessen & Tufte,

2003). By that means the ability of repeating the results of the study. According to

Lantz (1993) a way of increasing reliability in qualitative study is to use a guide as

support during interviews. Validity is however a measure of how well the data

represent the phenomenon that is being studied (Johannessen & Tufte, 2003). A way

of strengthen the validity is suggested by Yin (1994) as by using multiple sources of

evidence. The difference among validity and reliability is according to Holme &

Solvang (1997) that validity can be explained as absence of assignable causes of

deviation, reliabili ty means absence of random such. When conducting a qualitative

study, validity is less of a problem than in quantitative studies according to Holme &

Solvang (1997).

The reliability has been strengthened by using an interview guide. This guide had

previously been sent out to the respondents, giving them time to think making

remembrance less of a deviation factor. Further were several persons at GETRAG

asked the questions in advance making sure they were understandable to employees

in general. At the actual time of interview, the author did his best to ask the

questions similarly and with as little influence as possible. The research validity has

been strengthened by thorough planning and reading of reference theories, to ensure

data collected meets thesis purpose. The questions have further been validated and

discussed with an experienced academic. This person is Karin Schön, my supervisor

at Luleå University of Technology. When talking about validity, it is most important

that the respondents have needed knowledge to answer the questions asked. This

was as previously described, discussed together with GAWD Project Leader at

GAWD before deciding respondents. The total number of twelve respondents in a

qualitative study, together with both using Top managers and subordinates,

supports Yin’s (1994) statement of multiple sources of evidence.




With the position as resident engineer at GAP, as mentioned in section 3.1,

communication with top management as well as blue collars came naturally. The role

of resident engineer working at GAP for GAWD can further be illustrated by Figure

3-10. This strengthens the validity since own observations have occurred during an

extensive period of time, forming a holistic view of problems in hand.

Figure 3-10: The author’s role as resident engineer in summer of 2006

To minimize drawbacks connected to certain research methods explained in this

chapter, Nachmias et al. (1996, p. 206) suggest using two or more methods of data

collection; defined as triangulation. Since findings in both observations and

interviews have to some extent yielded consistent empirical result s, the validity has

been further strengthened.

Another source of assignable cause of variation is the author writing this report on

his own. Two students could have validated their methods used, in a more satisfying

way. The study was however initiated by the author together with Senior Quality

Manager and Projects Manager which left me alone as only choice. This was

compensated to some extent through support by supervisor, other thesis workers

and to the most, employees at GAWD.




4 Theoretical Frame of Reference

4.1 Total Quality Management Before presenting the different theories, it is important to define the word quality.

Bergman & Klefsjö (2003 p. 24) defines quality as the ability of a product to satisfy, or

preferably exceed, the needs and expectations of the customers. Another, shorter

definition by Juran (1954) is ―fitness for use‖, shared by Sandholm (2000, p. 11). The

above definitions can both be explained as regarding quality as something decided

by customers.

The meaning of Total Quality Management (TQM) can be described as the whole

concept of values, methodologies and tools to achieve higher customer satisfaction to

a reduced amount of resources (Bergman & Klefsjö, 2003, pp. 34-35). The connection

between quality and profitability may be difficult to identify and, according to

Sandholm (2000, p. 26), is often ignored by top management in benefit of pushing

sales, and lowering costs. The aim of TQM is to increase both external and internal

effectiveness. This can be exemplified by having a satisfied customer who keeps

coming back, leading to increased profitability (Bergman & Klefsjö, 2003). Another

intention is to reduce costs for poor quality, which can be as high as 10-30 % of

turnover (Sörqvist, 1998). As to clarify the relation between higher quality and

increased profitability, Bergman & Klefsjö (2003, p. 52) developed a model seen in

Figure 4-1.

Figure 4-1: Relation between higher quality and improved profitability

(Bergman & Klefsjö, 2003 )


Th b i f TQM d t th ti th l th t f th t d b lt f



The basis of TQM and at the same time, the values that form the nuts and bolts for

achieving higher quality, are by Bergman & Klefsjö (2003, p. 36) called cornerstones

and presented in Figure 4-2. Each of the values will briefly be explained below.

Figure 4-2: The basic values (cornerstones) of Total Quality Management

(Bergman & Klefsjö, 2003 , p. 36). The name of the lower right cornerstone

is by the author changed from ―committed‖ to ―participate‖, since

perceived a more proper translation from its in Swedish written origin.

Focus on customers

Quality is valued by the customers, in relation to their own expectations. Focusing on

customers means finding out what they want and need, trying to fulfil them in the

product development process. It may be difficult for customers to state their needs,

and it takes considerable empathy to understand what they actually require. Focus

on customers does not only apply to external customers, but also internal because

having satisfied external customers in the long run, takes employees with

opportunities of performing a good job. It is essential for the company that

employees feel satisfied in their current situation. (Bergman & Klefsjö, 2003, pp. 35-

38)

Let everybody participate

To have a successful quality work, it is fundamental to create incentive for

participation in the work towards customer satisfaction. That includes being actively

participating in the decision making as well as improvement work. Communication,

delegation and training are contributing factors to everybody’s commitment. The

ones given chance to do a good job and are recognized for it, will also be committed

to their job future wise. (Bergman & Klefsjö, 2003) Participation and commitment are

further achieved through delegating responsibility and authority, and the effect from

it can be explained by a model presented by Bergman & Klefsjö (2003, p. 46), seen in Figure 4-3.

Figure 4-3: Vicious and good circle related to delegation of authority and

responsibility (Bergman & Klefsjö, 2003 , p. 4 6)


Base decision on facts



Base decision on facts

Quality beliefs encourage to base decisions taken from facts rather than letting

random factors be of importance in the judgment. This is valid not only regarding

systematic collection of customer needs and requirements but also in the work

connecting them to the manufacturing business. (Bergman & Klefsjö, 2003) Usable

tools could be the Seven Management Tools explained in section 3.3.1 Plan.

Focus on processes

A process can be seen as activities repeated over time. It aims to describe a flow from

input of information or materials to an output with purpose to satisfy its customers.

To focus on processes further means to put concentration to what the system is

producing and the results it generates, rather than giving attention to individual

products or employees. It also highlights employee’s personal contribution to the en d

output, which may be conducive to motivation. (Bergman & Klefsjö, 2003)

Improve continuously

Customers constantly demand new technologies and products t o higher quality,

making continuous commodity quality improvements, of the essence to companies.

A company which stops improve its processes will soon prevent itself from

performing well. Cost of poor quality can, as earlier described, may be as much as 10-

30 % of sales (Sörqvist, 1998) which is one factor alone motivating continuous quality

improvements. (Bergman & Klefsjö, 2003)

4.2 Customer satisfaction

When talking about customer satisfaction it is important to put it in relation to

quality. Customers require experience with a product to be able to determine how

satisfied they are with it. Quality, however, can be perceived without actual

consumption experience (Oliver, 1993). Research studies shows customer satisfaction

to be dependent relative value (Zeithaml, 1988), hence also makes it dependent

relative price, which quality of a product or service not in general need to depend

relative to (Anderson et al., 1994). Further according to Anderson et al. (1994), quality

is customer’s currently perception of a good or service, when customer satisfaction is

ased on customer’s past, current as well as anticipated experiences of goods or

services.

4.2.1 Quality dimensions and relative importance

SERVQUAL is a method used for measuring service quality developed by Zeithaml

et al. (1990), and was at first based on ten dimensions. These ten dimensions were

later reduced to five since several of the original had correlation among themselves

according to Zeithaml et al. (1990). The SERVQUAL questionnaire consists of 22

statements covering the five dimensions seen in left column of Table 4-1. The

instrument can by a company be used to calculate its overall quality of service as

perceived by customers, according to Zeithaml (1990, p. 177). The relative

importance amongst the dimensions was studied and regardless of service, reliability

was proven most important to customer satisfaction, according to Zeithaml et al.


(1990). Tangibles were left as least important in the assessment of service quality. See



(1990). Tangibles were left as least important in the assessment of service quality. See

Table 4-1 for complete information.

Table 4-1: Dimensions of quality service and its relative importance to

satisfaction, as perceived by customers in SERVQUAL study (Zeithaml

et a l. 19 90 p. 28)

Dimension Weight Definition:

Reliability 32% Doing what promised

Responsiveness 22% Willingness to help customers and provide prompt help

Assurance 19% Conveying trust and confidence

Empathy 16% Caring, individualized attention the firm provides its customers

Tangibles 11% Appearance of physical facilities, equipment etc.

4.2.2 Gap model

There may be several different reasons for a customer to be dissatisfied with the

quality of a product or service, resulting in poor customer satisfaction. A model of

explaining causes of customer dissatisfaction has been developed by Zeithaml et al.

(1990). Zeithaml et al. (1990) focuses on analysing the gap in the service expected by the customer and the actual perceived service. The possible negative difference

between service expected and actual service provided is further explained by four

more detailed gaps, see Figure 4-4. The Gap model was originally presented to

explain service quality, but according to Bergman & Klefsjö (2003) the Gap model can

also be used to explain dissatisfaction in quality of products. The complete model

and its different gaps as presented by Zeithaml et al. (1990) are briefly described

below.

Figure 4-4: The Gap model as presented by Zeithaml et al. (1990, p 46)

Gap 1

The difference between what customers ex pect and what management perceives they expect.

This gap arises when management does not understand what the customer considers

to be critical to quality. According to Zeithaml et al. (1990 p. 52) a difference can on

the provider’s side be caused by; (1) lack of marketing research orientation, for example


inadequate use of market research findings, and lack of interaction between



q g

management team and customers; (2) insufficient upward communication, from contact

personnel to management, and (3) too many levels of management separating contact

personnel from top management. Gap 1 is normally considerably larger in service

companies than in manufacturing firms, according to Bergman & Klefsjö (2003, p.

324). One way of closing Gap 1 is, according to Zeithaml et al. (1990, pp. 56-57), to

research intermediate customers and their needs and expectations, which can be very

useful in obtaining information about end users.

Gap 2

The difference between the company’s perception of customer expectations and the service

quality specifications. According to Bergman & Klefsjö (2003, p. 325) it is sometimes

difficult to make the customer’s voice heard in the design process. Gap 2 is a wide

gap in many companies (Zeithaml et al. 1990). Main reasons for a difference in Gap 2

are (1) insufficient commitment to service quality, (2) lack of perception of feasibility,

(3) ina dequate task standardization, and (4) absence of goal setting. If the company is

lacking management commitment to service quality, a wide Gap 2 is guaranteed.

Example of such can be, management focusing on cost reduction and short-term

profit, since it is easier to measure and follow. (Zeithaml et al. 1990 p. 72) An action

to close Gap 2 is to obtain strong management leadership, where the commitment to

quality constantly and visibly is expressed to middle management.

Gap 3

The difference between the specified service and the service delivered. This third Gap occurs

according to Zeithaml et al. (1990, pp. 89-107) if employees are unwilling or unable to

perform a service according to specifications. Reasons for this can be differences in

theory and real life, and if the specifications are too complex or not aligned with

company culture. Reasons causing Gap 3 can according to Zeithaml et al. (1990) be,

(1) the personnel delivering the service have not been part of the service design, (2)

role conflict, (3) poor employee job fit, (4) lack of teamwork, (5) role ambiguity, and

(6) poor technology job fit. The most important actions to close Gap 3 is building

teamwork, allowing team members to participate in decisions a nd success of the

whole group (Zeithaml et al. 1990, p. 108). Building teamwork is not only regarding

internal customers and groups, but also towards external customers. (Zeithaml et al.

1990, p. 109)

Gap 4

Difference between the service delivered and the promised service. Zeithaml et al. (1990)

consider the difference in delivered and promised quality arise when a company is

not accurate and appropriate in its communication, leading to high potential of over

promising. Partly, a difference in this gap can occur from not informing customers of

quality efforts made, which are not visible to them. Some reason for this gap is (1)

insufficient communication within the company, and (2) propensity for over

promising. An action to close problem (1) is by opening channels of communications

among operations and sales/HR/customer contact personnel according to Zeithaml

et al. (1990, pp. 118-120). This can be made by frequent team meetings or workshops

where team members allow each other to understand goals and constraints of one


another. As key actions in closing propensity for over promising, Zeithaml et al.



(1990, pp. 123-127) suggest emphasizing primary quality determinants, managing of

customer expectations and help customers understand their role in creating

prerequisites for quality service.

Gap 5

Difference between customers expectations and perceived service. The fifth gap is the result

of the earlier four. The judgment of good or poor service quality lies in the hands of

customer’s perception of the actual service delivered, in relation to expectations,

according to Zeithaml et al. (1990).

4.2.3 The Mushroom effect

Bergman & Klefsjö (2003, p. 314) presents a model explaining customer complaints,

also supported by Zeithaml (1990, p. 54), where out of one hundred dissatisfied

customers only five actually bother to make their complaint known to the company.

Nevertheless, the one hundred customers who are dissatisfied feel no objection in

telling neighbours, friends and acquaintances about their disappointment, according

to Bergman & Klefsjö (2003). In total, as much as one thousand people may be

informed by one hundred customers not satisfied, whilst only five of them actually

reach company notice. Measuring only complaints is a n inadequate source of

information to customer satisfaction, according to Zeithaml (1990).

4.3 International business obstacles to quality

In this section common theories and values from different studies regarding

international business will be presented. This is interesting since GAWD project team

are members of an international product development process, thus affected by other

manners & customs. Culture has according to Robbins (2003, p. 529) a strong

potential dysfunctional influence on organizational effectiveness.

4.3.1 Cultural differences

Richard Pooley (2005) conducted a study of a joint venture among the two

automotive companies Renault and Nissan. Japanese design engineers was sent to

work alongside a German team of similar size and expertise. Already within days

several arguments arose, being very costly and inefficient to both companies.

According to Pooley (2005), the major problem can be explained as cross-cultural

difference, yet it is extremely rare for organizations today to deal with ways new

project teams run meetings, make decisions, manage staff and communicate. The

trouble is, according to Pooley (2005) that each culture interprets other cultures in

view of its own, and may make people loose faith of others who act deviant or

strange compared to oneself. Further according to Pooley (2005), it is risky to

imaging applying common sense as avoidance to cross-cultural problems.

According to Robbins (2003, p. 530) the same problems as mentioned above by

Pooley (2005) have occurred in a number of failed international acquisitions, where

the primary cause has been conflicting organizational cultures, according to Carey et

al. (1998).


Solutions to cross-cultural problems



Solutions to cross-cultural problems in organizations may be, according to Pooley

(2005), [1] providing a combination of key personnel cross-cultural- and intensive language

training, or [2] having a consultant joining the kick-off meeting helping team members learn

about cultural differences.

For the training to be successful (ibid);

1. You need to know your self and the behaviours normal to you.

2. Understand the facts that resolve your counterparts normal behaviour most

importantly regarding;

o Time - importance of punctuality and sticking to deadlines

o Truth – attitude towards honesty, right and wrong

o Relationships – attitude towards senior people in the organization

o Human condition – attitude towards risk and free choice

o Communication – frankness and directness appreciated?

3. Knowledge of how others see you, especially any negative perceptions

4. Learn to adapt

4.3.2 Explaining cultural differences

From studying over 110.000 IBM workers in more than 50 different countries in 1968

and 1972, Geert Hofstede (2001) developed four dimension s (later becoming five) for

examine cultural differences. The four different dimensions will briefly be presented

below and can be said to explain cultural differences.

Power distance

Power distance concerns the sharing of power in general, and between manager and

subordinates in particular (Hofstede, 2001). Further according to Hofstede (2001, p.

83), power distance is a measure of the perception of interpersonal influence between

manager and subordinate, in the eye of the subordinate. The dimension expresses to

which degree a culture accepts social inequality among its people. A culture with

large power distance tends to be more hierarchical and have much inequality

between superiors and subordinates, according to Wild et al. (2003, p. 67).

Uncertainty avoidance

This dimension identifies to which extent a culture is willing to avoid uncertainty.

According to Hofstede (2001, p. 145), a culture with large uncertainty avoidance likes

being surrounded by a feeling of security. In organizations, further according to

Hofstede (2001), this may be symbolised with strong system of rules and rituals,

making low employee turnover-ratios common. Example of rituals included in

uncertainty avoidance are the way of writing and f iling emails, accounting and

planning. A negative effect indicated by large uncertainty avoidance according to

Wild et al. (2003) is the difficult in implementing various changes within an

organization. Cultures with low index of uncertainty avoidance are according to

Wild et al. (2003, p. 68) more open to new ideas, and as an effect, have tendency to be

entrepreneurial. Since people from low index of uncertainty avoidance cultures are


more open to change, the staff turnover in organizations can be expected to be

hi h (Wild t l 2003)



higher. (Wild et al. 2003)

Individualism and collectivism

National cultures can be divided into being either individualistic or collectivistic,

according to Hofstede (2001, p. 209). A culture scoring high on this dimension

(individualist), value, according to Wild et al. (2003, p. 66), hard work and encourage

entrepreneurial risk taking. People may focus on their personal goals in high

individual scoring cultures, but are held responsible for their own actions. (Wild et

al., 2003, p. 67) Therefore individualist cultures can be expected to have higher

employee turnover rates. Individuals in cultures scoring low in this dimension

(collectivist) feel strong alliance to groups, and work toward collective in front of

personal goals in life. (Wild et al. 2003, p. 67) Success or failure in collective cultures

tends to be shared among the work group.

Masculinity and femininity

A feminine culture attach higher value to social goals like for instance relationship,

the physical environment and cooperation, according to Hofstede (2001, p. 279).

Masculine cultures are rather attached to ego goals in life such as career, earnings

and training. (Hofstede 2001, p. 281) Masculinity and femininity should not be

confused and considered similar to individualism and collectivism according to

Hofstede (2001, p. 293). The difference can be explained as ―I‖ versus ―we‖

distinction among individualism and collectivism when masculine and feminine

cultures are distinguished by ego or relationship enhancement, regardless of group

ties. (ibid)

4.3.3 Communication

Robbins (2003, p. 285) has outlined the steps between a source and a receiver

resulting in transferring and understanding of meaning. The steps, all together, are

by Robbins (2003) defined as the communication process and is presented in Figure

4-5 next page. Before communication can take place, a purpose is needed. The sender

(source) initiates a message by encoding an idea from his or her mind according to

Robbins (2003). A message is created, for instance when we speak, write or make a

gestures. The channel is the medium through which the message travels, and is

selected by the source. The receiver is the object to whom the message is addressed.

Before receiving the message, the receiver has to decode and translated to something

that is understandable to the receiver. Last part in the process is feedback to the

source by the receiver. It is not until feedback has been given, any check can be made

on how successful the communication process has been in transferring meaning.

(ibid)




Figure 4-5: The communication pr ocess (Robbins, 2003, p. 285)

Communication and culture

Communicating within the culture of your own may be difficult to keep effective

under the best of conditions. When communicating with other cultures, additional

elements make it even more difficult to maintain a successful communication level.

Munter (1993) has identified four specific problems related to cross-cultural language

difficulties in ma nagement environmental communication.

o Semantics o Word connotations

o Tone differences

o Differences among perceptions

To keep misperceptions and misinterpretations at a minimum level, Stephen P.

Robbins (2003, pp. 302-305) proposes to asses the cultural context of the counterpart.

The cultural context influences the meaning individuals take from what actually is

said or written. Robbins (2003, p. 304) further describes high context cultures, such as

China, Korea or Japan, to rely heavily on non verbal cues when communicating with

others. It might even be what is not said that is more important than what actually is said. The official status, reputation and place in society weigh considerably much in

high context cultures according to Robbins (2003). In difference to high context

cultures, people from European or North American culture’s rely essentially on

words, and belongs to low-context cultures, for details see Figure 4-6 below.

Communicating in high context cultures implies considerably more trust by both

parties. Insignificant and casual conversation is important in reflecting the desire to

build a relationship and trust in high context cultures, according to Robbins (2003).

Figure 4-6: Examples of cultures cla ssified from low- to high context

cultures. (Robbins, 2003 p. 304)


4.4 Quality and product development

A d ib d i 1 1 B k d it i i t t t d t d t ffi i t



As described in 1.1 Background, it is even more important today to conduct efficient

product development processes, both relative time and total amount of money spent.

Bergman & Klefsjö (2003, p. 58) presents a model explaining the relative cost of

design changes in product development, seen in Figure 4-7. The cost of making a

design change increases to the power of ten, when sequentially moving from one

step to another in the development of a product.

Figure 4-7: Relative cost of design change in product development

(Bergman & Klefsjö, 2003 , p. 5 8)

Sullivan (1986) conducted a study of number of changes made in product

development in a company from Japan respective one from America. The result can

be seen in Figure 4-8.

Figure 4-8: Number of changes conducted in a Japanese and an

American company (Sullivan, 19 86)

According to Ulrich & Eppinger (2004), organizational difficulties in product

development, mainly lie in level of power to the project manager. If a project

manager attributed limited power, or in other words lack of authority with respect to

function managers, it is either not sustained by top management. Ulrich & Eppinger

(2004) defines this as lightweight project manager. The opposite is when a project


leader has a degree of independence and authority in relation to the budget at his or

her disposal and has authority to allocate resources (called heavyweight). (ibid)



4.4.1 Product Part Approval Process (PPAP)

According to Automotive Industry Action Group (AIAG), the purpose of PPAP is to

provide evidence that all customer engineering design records and specification

requirements are properly understood by the organization. Further is also the

purpose to ensure that the manufacturing process has the potential to produce

products consistently meeting these requirements during an actual production run,

at the quoted production rate. (PPAP Manual, 2006) According to the iSix Sigma

website (2006), the Production Part Approval process outlines the method used to

approve service and production commodities in the automotive industry.

The process of completing PPAP, can be explained as a structured procedure of

documenting records from sample to set production part, divided into 18 steps, see

Table 4-2. The process of PPAP is based on QS9000 and adapted to TS16949:2002

quality management system (PPAP Manual, 2006), and the Part Submission Warrant

(PSW) shall be signed by customer upon completion of all required documentation.

The signing of PSW is at the same time a final sign-off that the PPAP process has

been followed. Customer and supplier agree upon if all steps need to be accounted

for in the PPAP documentation. Agreed submission level sets the evidence required

for completed PPAP process. In level one, only the PSW is required whilst in the

highest – five-, the PSW with product samples and complete supporting data seen in

Table 4-2, are reviewed by customer at its manufacturing location.

Special Characteristics

According to AIAG, a Special Product Characteristic is a product characteristic for

which reasonably anticipated variation could significantly affect the product’s safety,

or is likely to significantly affect customer satisfaction. The special characteristic is

indicated on drawing by a <M> sign if Major risk, <C> if critical risk and <A> if

liability risk (Internal training material, 2006). All special characteristics are obligated

to be controlled by Statistical Process Control (SPC), and showing capability of

Cpk>1.33. All special characteristics are presented in the no. 11 data sheet, seen in

Table 4-2. Special characteristics are the output of D-FMEA and P-FMEA processes.




5 Empirical result



In this chapter the data collected is presented, starting with introducing the Product

development at GAWD, followed by more specific information of the Theta project, ending up

with interview, focus group and observation data.

In the process of gathering information of problem areas to base improvement

suggestion on, the focus has been to investigate both the experience of such at

GAWD and the perception of ditto by its customer. How this mindset has evolved is

described in chapter 3 Method. Information presented in this chapter is based upon

interviews, focus groups and observations. To understand the different phases of

product development and its part of the business, it is important to understand the

general process of product development at GAWD. This is why this section begins

with an overall introduction to the process of developing new products at GAWD.

5.1 Product development at GAWD

According to main process map at GAWD (Business Management System, 2006),

three core processes are identified, Quotation to Order, Product Development and

Order to Delivery. In time they are ordered as seen in Figure 5-1 below. Out of the

three, Product Development contains the initiation of new projects.

Figure 5-1: Core processes at Getrag All Wheel Drive AB in Köping,

Sweden

5.1.1 GAWD Gate system

The model of managing projects, are at GAWD divided into ten different gates, see

Figure 5-2, called Gate system. It can be explained as a conceptual and operational

road map of cross-functional tasks moving from idea to launch of product. This effort

is divided into distinct separate stages (gates) detached by management decisions.

Members in the cross-functional project team must describe and show evidence of

completed set of tasks before getting management approval to proceed to next gate,

i.e. next step of product development. The individual requirements in each gate are

specified in a comprehensive checklist, stored in Business Management System and

can be seen in Appendix 3.

Figure 5-2: Getrag gate system, the process of projects (Business

Management System, 2006)


Design Reviews

Checklists of tasks are connected to Design Review meetings as to the Gate reviews,

i i 5 2 i i i diff f G i b i h ld



seen in Figure 5-2. Design Review meetings differ from Gate reviews as being held at

a considerably additionally detailed level, and as indicated by the name, focusing on

design issues. A further difference is the non compulsory presence of GAWD

management team.

5.2 Theta

The first external customer contact persons and concept designers are situated in

Detroit. They were rewarded the contract of supplying AWD-systems, when GAWD

in Sweden not yet was born, see section 2.1 History. The question GETRAG asked

itself was where to manufacture and assemble the final product, i.e. setting up the

supply chain. In November of 2004 the final plan was set, see Figure 5-3, letting the

newly acquisitioned plant in Sweden do the final machining of intermediate- and

input -shaft, along with complete pinion shaft and ring gear to the final Power Take

Off unit, see Figure 5-4. The ring gear is welded to the intermediate shaft, making it

three parts in total to dispatching from GAWD to GAP, seen in Figure 5-3. Delivering

PTU components to a customer is a new situation for GAWD, from previously

complete units. For the same reason it is predicted by the project team to be a project

of less magnitude than previously experienced.

Figure 5-4: Theta PTU with indicated GAWD machined parts


5.2.1 Organisation

The product development process at GAWD has eight main processes, called

d l i l th t i l l i d t i Fi 5 2 Th



modules, running along the ten previously explained gates in Figure 5-2. The

modules form the basis of the cross-functional project organisation and can be seen

in Figure 5-5. Since GAWD entered Theta when the conceptual design was already

set by GEC, only seven of the eight standard GAWD modules are applicable to

GAWD in the Theta project. That is why the author has shaded parts of the product

development process shown in Figure 5-5, to clarify GAWD responsibility in Theta.

GEC are responsible f or the design of all PTU parts in the unit, as well as all testing

activities. Prototyping is not shaded since GAWD still need to send prototype parts

to GEC for testing. The individual modules have a team leader with underlying part

project leaders.

Figure 5-5: Process of product development as seen in Business

Management System (2006). The inclined lines and the ―Not responsible‖

label are added by the author, indicating processes not applicable to

GAWD in Theta project. (RRT=Request and Response process)

GAWD entered the project in gate two, skipping the first two gates, zero and one,

since being asked by GEC to send production samples right away. The missing gates

were to be caught up later. GAWD, GAP and GEC are all within GETRAG, hence no

general contract is written among them before they all are engaged in Theta. GAWD

is at the time, at many places within the organization, still busy in its change

management from former being a Volvo company. A sales department is under

construction, making project leader responsible for requests processing from

customer. This process typically involves cost calculations and fea sibility agreements

of incoming change requests. The product development process, Figure 5-5 above, is

something that has been developed during the time of Theta project running, and

was not developed prior start of Theta. This thesis is composed subsequent the end

of project Theta, which present is controlled by regular production organization at

GAWD. One employee has been appointed overall leader of the continuous

interactions within Theta supply chain.


Below is the process of number one module ―Project management, planning and

closing‖ in Figure 5-5 seen in Figure 5-6. After every project, the project leader writes

a ―white book‖, which is a summarizing document of conclusions from the recent



a w te boo , w c s a su a g docu e t o co c us o s o t e ece t

project. It is intended to be read at start of new projects.

Figure 5-6: Process of module no. 1 Project management, pla nning,

control and closing (Business Mana gement System, 2006)

5.3 Problems

The personal interviews conducted, bring from an operational level, fourth a general

picture of perceptions of problem areas. As well as historical, also present issues have

been in focus during interviews. Areas are mapped by type, not connected to any

specific function and gathered in an affinity diagram (Appendix 4). Further, the

problems indicated are not presented in any reciprocal order.

5.3.1 PPAP documentation

As perceived by GAWD, no clear expectations and requests were by the customer

given from the start regarding layout and information in the PPAP documentation.

No regular meetings were either held. After a second person got responsible at

customer site, communication came along better. GAWD Senior Quality Manager

and Project Quality Engineer went to GAP in April of 2005. Together with customer

the general layout and information issues regarding PPAP were sorted out. The

forms used were mostly in Swedish, with English headers at the time. This was

something not brought much attention by GAP, at least not something understood

by GAWD. An interim Part Submission Warrant was signed by customer in end of

year 2005, and everything was running ok. Later a third, fourth and in April of 2006

also a fifth person in order, got responsible for coordinating incoming GAWD PPAP documentation at customer. By time, higher and higher level of adoption to fully

English forms was requested by customer, not satisfied with previously accepted

information layout. Customer requests were, especially by fifth responsible,

communicated very clearly and followed up in weekly meetings, very much

appreciated by GAWD.

The flow of design drawings has to some extent been sent to GAWD via email to

Project Leader, who has distributed them to project quality responsible for updating

PPAP documentation. Project quality responsible then sends updated information to

GAP. Awareness, of which drawing revision is the latest, has been confusing in the


project both for GAP and GAWD. The lead time of implementing changes and

distributing updates has by this gotten prolonged.



Further source of confusion to GAWD was and still is to some extent caused by the

usage of $ -signs in prints. No standard, to GAWD awareness, mentions anything

about the sign in this application, or how to interpret it. If it is a special characteristic

it will have to be kept under statistical process control. A third, issue of concern has been to get data from the Indian supplier, managed by GAWD Supplier Quality. The

incoming quality level has been poor, making it difficult assuring outgoing quality,

since incoming is not meeting requirements. PPAP process can not be closed towards

customer if supplier is not meeting set specifications. The two main problem areas,

according to GAWD has been [1] getting data from India and [2] not knowing what

the customer expects. See Figure 5-7 for summary as presented in affinity diagram.

Figure 5-7: PPAP main

5.3.2 Communication

First, as stated in section 5.3.1, project team at GAWD did not get in contact with

customer supplier quality function until fall of 2005. This made it hard to obtain

information of expectations from customer at an early stage. Information sent

between GAWD and GEC such as prints and new revisions of ditto are sent by email

to manufacturing engineer and/or project leader and not always reaching the correct

function on this side of the Atlantic. As new revisions are released, all parties are not always updated, which caused quality documentation not always based on correct

revision reaching customer.

Second, purcha sing at GAWD was to manage the Indian supplier without getting

information from GEC, but a price to pay. It is believed by GAWD that further

information was in GETRAG possession, but no information or statistics from earlier

projects or investigations of the supplier ever reached GAWD. GAWD are

responsible for its supplier’s actions, an d need to have pre-knowledge of its

performance. Any data available giving information obtained in the work of


choosing the Indian supplier would help purchasing department in the upcoming

work. As well as a poor communication of information back and forth to the US,

starting up communicating with supplier in India was very difficult for a long period



of time. It came along better in mid 2005 after having at least two Swedish engineers

stationed in India since middle of 2004, to GAWD expense. After conducting first

supplier evaluation, alerts were communicated to GAWD management without any

actions taken. A possibility of changing supplier was never an opportunity since a contract already had been signed by GEC.

Time difference is no element possible to change in it self; nevertheless all parties

have been influenced by it and, to communication, it has had a negative effect.

Compared to Sweden, the United States is minus six hours and India, plus five and a

half. Telephone meetings have mainly been held in the afternoon Swedish time. In

general, the time difference has increased the use of email as means of

communication. The different parties have attended meetings writing their own

meeting minutes, which have differed from each other afterwards, since interpreting

things differently. Members of project team also mention uncertainty and unawareness of who to send information to at customer.

Several key employees from purchasing department as well as manufacturing

engineering had to go to the supplier in India, setting up ma chinery and teaching

manufacturing skills. Home operation has by that suffered from shortage of

resources. Many key personnel not being present at GAWD in Sweden rendered

difficulties in communicating among project team and purchasing at GAWD.

Another confusing factor negative to communication is having different people

travelling to India over time. They have to some extent been employees having

ability to go but also adequate skill. It has not been clear to rest of GAWD

organisation who is in charge or who to make contact with in specific issues at

purchasing department. See Figure 5-8 for problem summary as presented in affinity

diagram.

5.3.3 Cultural inequalities

GAWD faces in Theta several new business cultures, a new German owner of

majority, an American customer and a new Indian supplier. Differences in



behaviours related to cultural inequalities were after a short while obvious, but

nothing more than common sense has been applied to solve inequalities. GAP and

GEC has no specific knowledge about Swedish culture, as well as GAWD not

knowing the culture of its American colleagues nor the external customer, prior

Theta project start. Among the most obvious inequalities between America and

Sweden indicated by GAWD respondents, is the manner of sending all managers

involved a copy of email conversations, not common at GAWD. Swedes are in

general being quiet and restrained compared to Americans who speak broadly and

need a lot of information in presentations, as an example. Ability of understand and

interpret customer requests later transforming them into tangible actions, has not

been clarified to people in direct contact with customer. Several of the respondents

mention it useful to their own holistic view and understanding, to physically be at

the customer plant. Then expectations have been better understood, but converting

the new cognizance to other project members at GAWD has still been problematical.

The biggest cultural inequality involves Indian culture. Purchasing department had

previously managed suppliers from Asia, but not India in particular. The task of

develop a new production line together was new to them. Other people with no

direct contact with India does not understand how it is to deal with them, blaming

the organization for inability of manage the Indian supplier. Time apprehension has

been problematic, wh ere Indian culture allows non punctuality and leaving from

meetings too much larger extent than Swedish. Language difference has also made it

very difficult in keeping regular conversations.

No one of the respondents has gotten any cultural training in particular. One

respondent recalls taking part of a one day India business culture-class in Stockholm,

Sweden, during time of Theta project.

Figure 5-9: Problem areas related to culture


5.3.4 Transition management

Something that can not be ignored is the reality of GAWD parallel to Theta face a

transition from a Volvo to a GETRAG company. Managers are to large extent, at the



start of Theta, busy in forming new processes and methods of working. Having no

previous experience with GAP or the external customer also contributes to a larger

distance in terms of comprehension from the start. A mental fear of a new situation,

has to some extent kept GAWD from satisfying customer requirements. See Figure

5-10 for problem summary as presented in affinity diagram.

Figure 5-10: Problem areas related to transition from Volvo to GETRAG

5.3.5 Organisation

As mentioned in section 5.2.1 Organisation, a sales department is under construction

during most of Theta project. This has made project leader responsible for the Sales,

Manufacturing Planning, Project Management as well as Project Controlling

modules, seen in Figure 5-5 section 5.2.1. In Figure 5-11 the organisation chart as well

as relationship to the product development process is presented. In general there has

een too much work on project leader’s shoulder, especially when large parts of

GAWD organisation is busy adapting to GETRAG from Volvo (section 5.3.4), not

giving Theta priority.

In beginning of Theta, GAWD had a project organization adapted to one customer

(FORD/Volvo) and one specific type of assignment. This means the organisation is

being guinea pig of a new way of operate. New for project leader is further being

responsible of purch asing and logistics towards customer, from before only

manufacturing planning.




Figure 5-11: Project organisation, as issued 2 006-04-11. Dashed labels

added by author to make connection to GAWD product development

process in Figure 5-5.

After purchasing completed a supplier evaluation process turning red, i.e. not being

approved, at the Indian supplier, it was obvious to them that GAWD faced two

alternatives; [1] need of extra managing resources to help the supplier onsite and/or

[2] alternative sourcing.

This message was given to management team without immediate response.

Purchasing manager admits he could have been more distinct in his leadership, and

emphasised the urgent situation better and earlier to management. The contract had

been signed by GEC making alternative [1] the only possibility, sending people to

India. Purchasers, preproduction engineers and material planners relieved each other in India, teaching supplier in day to day operations. More or less two-three people

have been at supplier since beginning of 2005. This has made it impossible for the

rest of GAWD organization to know who to contact in certain matters as well as

purchasing department lacked resources towards other projects. In end of 2005,

purchasing was given further resources, but then it was too late.

The steering team, seen in Figure 5-11, is the supporting and managing function to

projects. It is represented by GAWD management team including managing director.

Together, Steering team and project team are to meet regularly. In Theta, steering

team meetings were held in late 2004 and beginning of 2005, then they stopped since the number of persons present in meetings was insufficient. This is indicated by

some respondents to be when strong leadership was needed the most. See Figure

5-12 for problem summary as presented in affinity diagram.




Figure 5-12: Main problems related to organisation

5.3.6 Supplier

First, the supplier in India was chosen by GETRAG in the US. This was before

GAWD entered Theta, hence had no chance in taking part of supplier evaluation

preceding the decision. The production had to be built up from scratch, and against

the clock. Local engineers and operators at the Indian supplier are desirable and

head hunted to other industries in India, after gotten special training by GAWD

engineers, leading to high staff turnover.

Parts were received at GAWD as from beginning of year 2005. The incoming quality

level was poor, and made 100% receiving inspection compulsory. The low incoming

quality level of parts as well as low volumes, made it, as previously described in

5.3.1, impossible to approve quality from supplier.

A negative spiral has spread it self internally according to some of the respondents,

due to severe supplier problems from hearing the name of the Indian supplier, or

simply India. A consequence is low motivation among employees and a domino

effect, GAWD making own mistakes due to time pressure since forced to work

overtime and do extra operations. See Figure 5-13 for problem summary as presented

in affinity diagram.

Figure 5-13: Main problems related to supplier

5.3.7 Collaboration

GAWD has had a customer with a customer-supplier relationship within the

GETRAG umbrella, without any written contracts. Several of the respondents

mention confusion and role ambiguity when asked upon the GETRAG overall

project organisational structure. Roles within GAWD has to some extent been

confusing, but general process awareness and relation to GAP and GEC operations is

yet today missing, though getting better. The GAWD impression from GEC and GAP

is that it should not question anything about customer operations, only deliver three

parts within specifications, nothing more nothing less, though all being GETRAG

companies. See Figure 5-14 for problem summary as presented in affinity diagram.

Figure 5-14: Main problems related to collaboration among GETRAG

companies


5.4 Customer view

A general customer view of GAWD has been obtained through personal interviews

at GAP and a telephone interview with GEC as described in section 3.3.2 Do. General

expectation of GAWD by its customer GAP is to deliver on time, have good quality



p y , g q y

followed by correctly filled in documentation.

5.4.1 GAWD Potential improvements A general improvement factor to GAWD in Theta indicated by both GAP and GEC is

meeting and respecting deadlines with correct documentation. This is to the most

connected to quality documentation, and interpretation of communicated

expectations. Both GAP and GEC believe they have communicated expectations

clearly, but see the problem to be GAWD not always understanding the meaning of

the expectations. It is by that believed that GAWD do not have the cultural

knowledge required. Brought up by respondents is also the GAWD’s ability of

managing the Indian supplier, as well as question the authority level of its project

leader.

Internal GAWD communication among project team and purchasing department is

seen by GAP as lacking. It is admitted that since GAWD appointed an overall project

leader responsible for both incoming and outgoing management at GAWD,

described in section 5.2.1, internal communication has become very much improved.

Further potential improvements regarding PPAP documentation is the level of

attitude towards customer requests from GAP. PPAP coordinator at customer

perceives GAWD to defend or explain their own methods as correct, when it is GAP

who has most experience with the external customer and its specific requirements.

GAP further indicate a ―over promise – under deliver‖ manner connected to

documentation sent to them from GAWD. That regards incoming documents both to

supplier quality as well as project department. Further confusion regarding

documentation is new print revisions connected to PPAP reaching GAP. Whether

GAWD have not understood the expectations communicated to them or not is

nothing apprehended by GAP. Main problem with PPAP documentation and its long

taking time is connected to having a forced supplier. One respondent put it like this:

The Indian supplier know for sure that GAWD is going to buy from them, hence not

doing their best. This problem is estimated by a respondent at GAP as corresponding

to 60% of the problem connected to PPAP.

5.5 General goods and improvements

During personal interviews, key performance indicators were asked. Not everyone

had anything to say, but the general impression can be seen from data in Table 5-1.

The topics mentioned are presented in overall order of frequency, with most frequent

in top of each column.

5.6 Improvement suggestions

Data from sections 0 (Appendix 4), 5.4 and 5.5 were presented to respondent team in

a workshop named ―Improvements in focus‖. Suggestions of improvements were

then generated by respondent team by using a Tree Diagram; results are presented in

Appendix 5. The question asked was ―How shall GAWD improve problem areas

identified in Theta to reach higher customer satisfaction?‖

6 Analysis

The analysis chapter focuses at finding equalities or inequalit ies among theory and empirical

results. This is made through determination of cultural differences, reasons for dissatisfaction,

d idi it f bl di fi di j i t



deciding gravity of problems, ending up finding major improvement areas.

Since quality is viewed from the eyes of the customer, this chapter will, after differentiating among culture, focus on th e customer assessment which via own

indicated problems gradually are broken down into actions providing higher quality.

The results will later be analysed according to cultural differences, why the chapter

begins with differentiating among traditions and customs.

6.1 Cultural differences

In Figure 6-1, the four dimensions of culture developed by Hofstede (2001) are

shown in two different diagrams, explaining two each. Instead of presenting all

different cultures originally examined by Hofstede (2001), four has been chosen by

the author to be most interesting to this study. Sweden, India, the United States and

Germany, since the first three affects GAWD directly in the supply chain, and the last

indirectly, since being the GETRAG culture of origin.

Figure 6-1: Cultural differences along Hofstede’s (20 01) four dimensions differentiating among cultures. (Which cultures to present have been

adjusted by the author).

Looking at the left hand side diagram of Figure 6-1, Swedish culture is far more

feminine than the other three cultures (Masculinity). Hofstede (2001) proposes

feminine cultures to be characterised by putting relationship and cooperation in front

of a more ego oriented mindset. Swedes can by this be said to be much more

cooperation minded in general, than its three reference cultures. German culture is in

Hofstede (2001) study, the most ego oriented culture, putting career and earnings in

first room relatively speaking. Focusing on Individualism, which is not to be


regarded equal to masculinity, gives an indication of the United States culture as

being most individualistic, i.e. value hard work and risk taking but are in

organizations responsible for their own actions. Sweden and Germany are in this

dimension some what less equally individualistic while Indian culture is the most

collectivistic; hence feel the strongest alliance to groups.



; g g p

If instead looking at the right hand side diagram of Figure 6-1, Swedish culture is

least expected to be avoiding uncertainty, according to Hofstede (2001). That, in

organizations, can be symbolised with weak level of set rules and rituals, exemplified

by the way of writing emails according to Hofstede (2001). India, United States and

Germany are in that order defined as cultures more expected to seek feeling of

security. When it comes to Power Distance, India is the culture scoring highest,

making further distances among manager and subordinates common. United States,

Germany and Sweden have closer distance among chief and employer with Sweden

scoring the lowest.

Robbins (2003) proposes to asses the context of a culture when mapping differences among such. India is the one culture of the four mentioned that can be identified as

high context and value body language and what is not said to be more important

than what is actually communicated by words. The other three mainly rely on what

is verbally communicating.

6.2 Customer satisfaction

According to Table 5-1, the issue causing most customer dissatisfaction is not

meeting deadlines and understanding how to fill in the PPAP documentation. An

over promise – under deliver situation is being mentioned. Meeting deadline with

documentation after made agreement can be connected to reliability, seen in Table 4-1 now modified and seen in

Table 6-1. Reliability has the greatest influence (32%) of a customer’s total impression

of delivered service/product (Zeithaml, 1990) and Bergman & Klefsjö, 2003). The

effect is that there is great propensity of the customer speaking negatively in general

of the company delivering the service, if not being fulfilled. A risk is this negative

influence being spread to people even not involved, as the Mushroom model (section

4.2.3) explains (Bergman & Klefsjö, 2003), perhaps giving an even worse reputation

than deserved.

Delivering documents or other information on time does not mean the customer will turn delighted. It will just become satisfied. The same goes for receiving documents

long in advance. A customer does not become further satisfied if receiving peaces of

documents two or three days in advance rather than when agreed. Any delay or

potential misinterpretation from provider’s side has to be communicated in advance.

This is an important improvement factor for GAWD, and influences the general

impression of GAWD the most – reliability according to Zeithaml et al. (1990). A

tendency of concentrating communication to times when quality issues have already

happened has been observed. Exchanging skills and experience within GETRAG


value chain continuously over time, and listening and trusting its competence world

wide, is a future step towards a further efficient transmission manufacturer.

On the other hand, GAWD show evidence of performing well in solving urgent

problems. This is verified by customer, who believe GAWD to be quick to react

(Table 5-1), when facing an urgent problem. If comparing this factor to



Table 6-1 of relative importance to customer satisfaction, it shows to be the second

most important factor, according to Zeithaml et al. (1990). The three remaining

dimensions of quality service by Zeithaml et al. (1990) can not, out from the empirical

study, be distinguished whether perceived as fulfilled or not by the customer,

therefore are they not mentioned.

6.2.1 Reasons for dissatisfaction

If using the Gap model developed by Zeithaml et al. (1990) to distinguish a mong

reasons for customer dissatisfaction, it can first be determined that no past

experience or word-of-mouth influences the customer’s expected service. Only the

customer’s need does. The five gaps found in the Gap model will be analysed below.

More detailed information of the Gap model can be found in chapter 4. The analysis

is presented in order of number, not importance.

Management perception of customer expectation (Gap 1)

The PPAP will be in focus, since mentioned by customer as where most expectations

interpretation was lacking. The management can be interpreted as project management team. Their experience from PPAP prior Theta is located to three

projects, presented in Table 6-2 below. In the three previous projects using PPAP, all

headers and layout has been according to GAWD own developed sheets, fulfilling

QS 9000 standard. All information has previously been in Swedish, apart from little

information in English to an earlier project labelled FIAT.

Table 6-2: Previous PPAP experience

Projects with PPAP Customer Language Notes In all three first projects, GAWD have used their own routines and P24 Volvo Swedish sheets, filled in required data and sent it for customer examination.

D219 Ford Swedish

FIAT Fiat Swedish/English GAWD thought everything should be as before, except changing headlines to English. This was later changed to all English and

Theta GAP English according to customer used layout.

GAWD’s ability to interpret and manage customer demands, together with

insufficient top management leadership and indistinct messages from customer has

contributed to a wide difference among the perceived customer expectation and the

actual expected PPAP. Actions diminishing this gap in future projects are:

o Further training of project members in PPAP


o Further customer expectation research in

project

o Higher degree of interaction among

customer and project management

Q lit ifi ti (G 2)



Quality specification (Gap 2)

The absence of regular Steering Team meetings is evidence of lacking management

commitment to Theta project team. Their commitment to quality can also be

questioned, since cost reduction and deliveries are communicated in front of quality.

Maximising the internal service quality will have effect of increasing motivation

among employees. The potential improved support delivered from other

departments as well as management in the organization will make it easier for

individuals to fulfil their roles in the value chain and provide better service quality to

supply chain customers. Indicating trouble in organising latest drawing revisions

among the GETRAG companies raises a need of a common information database,

making sure everyone uses the latest revision. The drawing and their new revisions

in case of change are managed by GEC since having design responsibility. Setting

objectives, trust of other party’s knowledge, as well as writing agreements/contract

among the parties is as important as in any other customer supplier relation. The

absence of strong leadership and goal setting has increased Gap 2. Actions closing

this gap are;

o Strong management leadership and Steering

team presence

o Top Management communicating quality

commitment to middle management

o Defining scope of project together with GAP

o Standardization of work through agreements

o Standardization of information flow

Delivered quality (Gap 3)

Role clarity within GAWD purchasing, and also what role GAWD plays in the

overall GETRAG project team is confusing to some respondents. Respondents also

mention that they are clear on GAP in the US, being their customer, but others see

them as partner and the external buyer as customer. Both of them can be seen as

customer but important is to have the same apprehension. This is something not

clear to all, and needs to be sorted out making everyone work towards the same overall goal and have total process awareness. In future projects, the supplying units

would benefit from taking earlier part in the product development process and share

their expertise. This interaction optimizes product and process design towards

customer satisfaction. It will also make the manufacturing plant further involved and

motivated (Bergman & Klefsjö, 2003), as far as feeling part of the project and valuable

to it, not to mention enlarging profitability and competitiveness to the whole

company (Figure 4-1). The indicated role conflict contributes to a wide Gap 3

(Zeithaml et al., 1990). The same is created by lack of teamwork and role ambiguity,

which ca n be found both between GAP and GAWD as well as GAWD purchasing


and project department. The best way in closing this Gap according to Zeithaml et al

(1990) applied to GAWD is by;

o Build further relationship and teamwork

among purchasing and project department

B ild f h k i h j



o Build further teamwork with customer project

team

Service delivered and promised service (Gap 4)

Perhaps Gap 4 is the most important gap to keep small since affecting reliability. This

gap is in Theta widened by difficulties in getting products from the Indian supplier

making it hard to keep promises. But what is not caused by the supplier is the lack of

information why deadline will not be met and when will, by GAWD project team.

Realistic dates must be set and communicated in advance if it will not be met. As

Zeithaml et al. (1990) proposes part of the reason may have been caused by GAWD

not informing the customer of quality efforts made. Even though Swedish culture is

based on a reserved manner compared to the United States, it has to learn to inform

the customer about its efforts to a larger extent.

The author sees a lack of internal communication among purchasing and project

team. Purchasing was short on resources, and many of them travelled to India,

making it difficult for everyone within GAWD to be aware of who was in charge of

purchasing. Face to face meetings were not either possible. Actions closing this gap

are;

o Informing the customer of its important role

in creating prerequisites for high delivered

quality

o One person responsible for purchasing over

time, not travelling too much

o Informing customer of quality efforts made

Customer expectation and perceived service (Gap 5)

No data can be found at GAWD of the customer perceptions of services/ products

delivered. Such data is something useful in both getting to know yourself from a

customer perspective as well as you about the customer.

6.3 Gravity of problems

The respondent team put votes to the collection of problems gathered in the

empirical study (Appendix 4), leaving the result shown in Figure 6-2 on next page.

All five members disposed 9-3-1 valued votes, giving 9 to what they perceived the

prevalent problem affecting GAWD in Theta. The diagram agrees with the 80/20 rule

developed by Vilfredo Pareto and described by Harry et al. (2000), where ―no

supplier choice conducted by GAWD‖ and ―communication problems among

companies‖ are the ―vital few‖ (88%) and the rest are the ―trivial many‖. Focus

should lie in solving the vital few problems.

Figure 6-2: Result from voting process in affinity diagram 2006-11-24 by

respondent team, answering the question: What has been the biggest

problem affecting GAWD in Theta project?

6.3.1 Supplier Choice

As Hofstede (2000) proposes, Swedish culture can be described as feminine and used

to low power distance, giving authority as well as responsibility to subordinates.

American culture and to some extent also Germany not to mention India, further

accepts distance between managers and subordinates. With that comes another

culture of communicating. GAWD were not involved in the decision of contracting a

specific supplier. This decision was taken above their head and prior GAWD

involvement in Theta, given in their lap to take care of. Delegating responsibility

should be accompanied with authority (Bergman & Klefsjö, 2003). Bergman & Klefsjö

(2003) suggests an approach of improving profitability through internal and external

quality (Figure 4-1) built upon everybody’s participation and basing decisions on

facts (Figure 4-2). Since the sub supplier contract was signed, no possibility of

changing supplier was available. The people taking care of the problem had not been

part of the process design. No particular information was given from the people

involved in the supplier choice process that actually took place. Altogether in view of

a Swedish culture, based upon collaboration and relationship, this is a source of low

motivation. No one in the respondent team believes they are better in conducting

supplier choice processes than anyone else, but they want to participate.

A parallel can be drawn to Figure 4-3, indicating lower employee motivation and

inferior result if not delegating both responsibility as well as authority. Further it

may cause lack of management confidence among staff who then can find motive in

speaking negatively about the supplier and even about own top management,

according to the Mushroom model (Bergman & Klefsjö, 2003; Zeithaml et al., 1990).

Perhaps this problem has been magnified in proportion since Swedish culture is

―feminine‖ to its nature (Hofstede, 2001), and value cooperation to further extent

than if it would have been in a United States or in a German culture.


6.3.2 Communication

The second highest total vote was by the respondent team given to ―communication

among companies‖ in the product development process. If recalling the

communication process (Robbins, 2003) in Figure 4-5, now seen in Figure 6-3,

problems can be identified to the encoding, decoding and feedback processes.



A higher level usage of email conversations, as time a nd language difference has contributed to, at the same time increases misunderstandings among value chain

companies. As well as a need of expressing messages interpretable to receiver party,

the receiver needs decoding skills. Since none of the project members have received

any cultural education, the process of adapting and learning other parties every day

natural routines, has taken a long time. According to Pooley (2005) it can be

explained as cross-cultural problems, where knowing your self and normalities to

you and the source are necessary conditions in order to understand and interpret

your customer properly. Receiver party play an important role in informing and

giving the source feedback of its way of expressing messages, letting him or her

know about possible improvements.

Feedback

Figure 6-3: Analysis of communica tion and problems indicated in Theta

An early Kick-off meeting accompanied with further face to face meetings within

GETRAG is of most importance in building a relation and process awareness among

project members. The inviting plant should be the one last in GETRAG supply chain,

closest to customer. Early personal relationship diminishes misinterpretation and

stimulates communication and cultural knowledge. The money spent on travel will

be won in a holistic view and minimization of Gap 1 and 4 in the Gap model

(Zeithaml et al., 1990). At the time for the Kick-off, Pooley (2006) suggest using an

expert in the cultures in hand, teaching cultural differences and help team members

communicating efficiently. GETRAG has during 2006 developed a cultural training

program (Vision Aug, 2006) which all GAWD project members should attend in the 3 beginning of a project.

External communication is af fected by internal communication, which has been

deficient especially between purchasing and project department. Seen in Figure 6-4 is

a schematic illustration of problem areas in communication identified to PPAP. The

purchasing department is indicated by SQA (Supplier Quality Assurance) who has

been low on resources during long period of Theta. Many members of purchasing

department have been forced to more or less be stationed at the supplier in India and

GETRAG World wide company magazine 3


support them in setting up production to assure capacity and quality level. It has

rendered role ambiguity and loss of communication to project department. The

inadequate level of product and process quality at supplier in India has had the effect

of a postponed approval of incoming PPAP to GAWD. If project department not

know who is in charge at purchasing at a given time, the risk of information loss is

great. Customer contributed confusion is also indicated in Figure 6-4 where



g g

communicated expectations have changed over time.

Figure 6-4: Communication problems in PPAP

If both parties agree upon using everything according to the latest PPAP Manual, in

English it will in the future generate less confusion and misunderstandings among

the parties. The need of preset statement of work and agreements valid over time is

evident. PPAP agreements that would help in this problem and must be stated before

the start of a project and kept during time running is;

o PPAP Part Submission level

o Layout

o Language

o Interpretation of special

characteristics

An agreement such as Quality Agreement developed at GAWD, has the purpose of

solving the above stated problems. The document contains a contact list of all project

members as well as standardizing responsibility in quality issues and everything

concerning PPAP a mong the customer and GAWD. In Gate 0 (Figure 6-5) of the

GAWD Gate System (Figure 5-2), the activity of negotiating Quality Agreement with

customer can be seen. This activity has in Theta however never been signed, though

efforts of communicating its purpose to the customer GAP. Among the activities in

Gate 0, the author has marked five in rectangles in Figure 6-5. These have not been

signed in Theta. Probably this is because both GAWD and GAP are members of

GETRAG Group and the activities may have seemed manageable from applying

common sense which this thesis show cause role ambiguity miscommunication and

misinterpretations. The above mentioned problems could have been settled if the

agreements in Gate 0 had been prioritized from the start. Gate 0 activities are at the

same time as connected to communication also directly connected to closing of

problems identified in the analysis of Gap 2 of the Gap-model in section 6.2.1.




Figure 6-5: Extraction of activities in Gate 0, with indicated missing

agreements in Theta (GAWD Gate review, 2006)

Project organisation

The project organisation belongs, according to Figure 6-2, to the trivial many of

problems affecting GAWD in Theta. Two changes regarding project organisation

have however been made at GAWD during the time of this study that affects [1]

strong leadership indicated in section 6.2.1 (Gap 2) and [2] internal communication

which is identified as a problem both in sections 6.2.1 (Gap 4) and 6.3.2, which is why

the project organisation is further analysed.

First change is adding a position called ―project management‖ to GAWD

management team and is supported by the author. This would hopefully give the

project team higher priority, which can be referred as supporting the heavyweight

project leader described by Ulrich & Eppinger (2004). If project activities are given

higher priority within GAWD production, the higher potential of project department

designing an even better production process to future production. It would lead to a

more efficient product development process, rendering higher customer value to

lower use of resources, i.e. higher quality as defined by Bergman & Klefsjö (2003). A

connection between having a committed steering team and strong leadership giving

project high priority and authority (heavyweight project leader, Ulrich & Eppinger,

2004) and improved profitability can be seen in Figure 6-6. The customer and its

needs should always be in focus, symbolised in Figure 6-6 by having a central role.




Figure 6-6: Connection between higher project priority and improved

profitability

The role of the project management position should according to the author not be as

main responsible for a specific project in hand, but developing the project

organisation and allocating resources adapted to each new project. Focus should lie

in creating prerequisites to each and every new project organisation to be as efficient

as possible in satisfying the customer. Examples of actions coordinated by this

position could be, project leader and cultural training offsite events.

The second change in process within project organisation is having a program

manager in each project, according to the model seen in Figure 6-7. Compared to

Figure 5-11 in section 5.3.5, two project leaders labelled E (Development) and W

(Manufacturing) will in large project have responsibility of five of the eight modules

og GAWD Gate System and report to the Program Manager. The project leader seen

in Figure 5-11, corresponds to the W project leader in Figure 6-7. Coordinating all

modules was too much work on current project leader’s shoulder, which supports

the change. Since previously describing a need of improving internal

communication, especially among purchasing and project management, this new

product development organisation is very much supported by the author. The

program manager coordinates both incoming and outgoing flow of goods and

service which adds a holistic view and higher potential of realistic and correct

customer communication, important in closing Gap 4 of the Gap-model.

Figure 6-7: New project organisation setup




7.2 Micro level

A Steering team committed to quality, communicating and supporting project team

in their work is the first step to make at GAWD towards customer satisfaction.

Steering team meetings must be held consistently and have the responsible people

attending. Further prerequisite for high delivered customer satisfaction, is GAWD

conducting a supplier choice process based upon deliverability, product quality as



well as price paid. The project organisation at GAWD needs a program manager

coordinating both incoming and outgoing activities at GAWD in projects, ensuring

communication among purchasing and customer contact persons. The propensity of

over promising may, by adding a Program Manager, be diminished and is important

to so also do, since affecting customer satisfaction most negatively. This

reorganisation has already started at GAWD and is supported by this study. What is

further recommended is adding a Project Management function within GAWD

management team, who does not manage any specific project, but organising and

continuously improve the product development process. This adds authority to the

project organisation as well as strong leadership. Project leader- and cultural training

events could be activities managed by this position.

Anyone in contact with customer from a foreign culture is recommended to presume

receiving party not knows about Swedish culture or the process behaviour at

GAWD, and has a responsibility of communicating any misunderstandings or

quality actions made in home operations. Swedish culture is built upon

collaboration, to some extent yielding unwillingness of bragging in general. GAWD

is recommended to develop further extrovert ability since this is something further

normal to the culture in the US.

Figure 7-2 below indicates the important recommendations in improving customer satisfaction connected to the timeline of GAWD Gate System. Highlighted are

activities of planning and training before the start of a new project as well as the

importance of a Kick-off face to face, together with GAP.

Figure 7-2: Recommendations improving customer satisfaction and

increasing long term profitability


The existing project management module of product development at GAWD is seen

in Figure 7-3. The competence and resource assurance circled in the figure must

include any training such as, culture, language or specific technical skills, beside

number of man hours needed in the project. The newly added Program Manager

should be responsible for this document in collaboration with Project Management in

GAWD Management team. Theta shows the need of training regarding culture,

language and technical skills needed in order to understand the customer correctly



language and technical skills needed in order to understand the customer correctly

and above all, translate it into correct actions actually fulfilling customer demands. A

simple but highlighting recommendation is to add ―competence‖ to ―resources‖ in

the project management process seen in Figure 7-3. This puts focus on planning not

only man-hours but also training activities adapted to a specific project and customer

in hand.

Figure 7-3: Project management process change recommendation.

Competence in the circle is added by the a uthor to the existing process.

7.2.1 Frequent evaluation

The customer evaluation activity, indicated in bottom of Figure 7-2, is a

recommended way of getting information of how the customer perceives GAWD,

what its strengths and weaknesses are. Today GAWD collect their own conclusions

from projects in a ―white book‖ document in the very end of each project, seen far

right of Figure 7-3. No customer feedback or expectations is collected in the ―white

ook‖. GAWD gain from actively be searching for activities increasing customer

satisfaction, and finding them as quick as possible during projects. Measuring a

general impression by a customer can be said to assess the decisive factor for how the

customer will act in the future. The same is valid for the way the customer will speak

about GAWD with others, recommending it and its AWD parts and products to

others. This does not only concern external customers but also internal within GETRAG.

An evaluation sheet, useful in collecting a general customer satisfaction index (CSI) is

presented in Appendix 6. By asking the customer of its perception of GAWD, gives

feedback of what GAWD does either well or can improve. It will in the longer run

make it easier to understand the external and end users. People responsible in

engaging the CSI study should be Project Leader/Program Manager in each project,

giving the customer project team a chance of filling it in. After collecting the

qualitative and quantitative data, it should be summarized and generate an action


list. Within a short period of days or a week, this action list should be presented to

the customer giving feedback from the recent made evaluation and explaining

actions taken and expected date finished. If this feedback is not given, the customer

may loose confidence in any improvements actually made an d will not either fill in

any future evaluations.

The frequency of evaluation should in different projects be individually decided,



q y p j y

since differing widely from each other both in time and scope. At least two times

during a running project is recommended. Differences in data collected between

made evaluations are information subject to analysis. Using a simple diagram of the

average value of CSI and number of respondents gives feedback of any

improvements made. The evaluations also physically show the customer of

continuous improvement efforts made by GAWD, which is identified as an

improvement factor affecting reliability. The source of information gathered from

customer evaluations could even be interesting to show presumptive customers since

it is an unbiased assessment of GAWD strengths and improvement possibilities.

The evaluation sheet (Appendix 6) is at its simplest form. This is no coincidence.

First, to measure the total impression gathers all aspects of the product development.

Second, it will measure the perception of GAWD as partner in product development

processes and the likelihood of the respondent to talk positively or negatively about

GAWD, since based on total impression, according to Bergman & Klefsjö (2003).

Third, any issue written as either good or as a potential improvement, will be the

most significant one, since only having three choices and limited time in filling them

in. Fourth, the GAWD administration time will be kept to a minimum, when having

one quantitative- and at most six (if no comments) quantitative -data to handle by

each respondent. All together, there is a high probability of catching twenty percent

of the issues causing eighty percent of the problem, according to Paretos 80/20-rule

(Harry et al. 2000), and that to lowest possible use of resources. According to

Claesson (2006) this type of frequent evaluation would be very useful for continuous

improvements of projects. Cleasson (2006) emphasises the need of follow up

recorded issues together with customer in soon connection to conducted evaluation.

All the data generated by the evaluation, or summarized, should be added to the

―White book‖ of each project. It will make the ―white book‖ contain even more

valuable data than today, and may also to further extent actually be used. New

projects then have the ability to read of old lessons learned and customer

expectations, in the beginning of new projects.


8 Discussion

This chapter discusses limitations and reflections of the study.

As to all research, the result is always influenced by the researcher. Some

circumstances affecting the output of this study will be mentioned below.



Since most empirical data come from interviews, the respondents and their actual

information given, has a major effect of the outcome of this study. Any information

given by a potential respondent not aware of the Theta project in detail, will add to a

biased result. The choice of who to interview was taken by Project Manager and

Theta Project Leader. This ensures every respondent are aware of the project and

enriches the study toward its correct result rather than not.

The interviews conducted at GAP and GEC were at first planned to be larger in

numbers. This was however not possible, caused by unpredictable conditions and

time limitation. A greater number of respondents at GEC and GAP could have validated the customer opinion and expectation, in a further satisfying manner. All

interviews have been conducted individually and in conference rooms, making

influence from other colleagues less of a disturbance factor. Since the author is a

GAWD employee, influences from knowledge based upon long term relation and

personal interest may to some extent form a certain unaware interviewer effect in

interviews. The intention has been to ask the questions from the interview guide,

without bringing in outside thoughts.

A source of deviation is the author creating the headings and layout of the affinity

diagram oneself. It is suggested as being a team exercise by Klefsjö et al. (1999). The respondents got a chance of presenting contradictions or other opinions to the

affinity diagram, before putting votes to it. However since affinity diagram in detail

was a new tool to all participants, there could be a possibility of them not knowing

exactly what to look for, even though explained to. Further source of deviation is not

all people interviewed did participate in the voting process of the affinity diagram,

hence some people’s opinion creating input to the diagram was not heard.

To separate among national cultures is difficult. Deviations among both occupations

and geographical belonging within a culture can be assumed and bring some

deviation to the Hofstede (2001) study. However it is interesting to differentiate among cultures in general and distinct among the rough similarities as well as non

similarities effecting cooperation among them. The study was conducted in late 60’s

early 70’s, and the prospect of the values to have changed since then should be seen

as granted rather than as a possibility. It is however the largest study yet made and

as Hofstede (2001, p. 145) self expresses it regarding one of the dimensions

―Although uncertainty avoidance levels do fluctuate over time, the difference among

countries on which the index was based are robust‖.


It is appropriate to once again mention the Gap model measuring reasons for

dissatisfaction. Obtaining a delighted customer from applying Gap model should not

be expected, contrary disregarded, since the customer can not even tell what

delight’s him or her. The theory was originally developed in explaining service

dissatisfaction; however Bergman & Klefsjö (2003) deem its suitability to products as

well.



Some external affect of the design and choices of the report may lie in minor

contradiction in satisfying two customers, Luleå University of Technology and the

commissioner GAWD.

Several different businesses should face similar problems like the ones dealt with in

this thesis, as globalisation occurs in far more businesses than only automotive. The

cultural aspect of the thesis discusses Swedish cultural and normalities to it. A firm

engaged in Sweden – American activities would probably benefit from the results,

but if outside Scandinavia or even Europe, some specific cultural a spects may most

likely need to be applied before making any conclusions.
