ABSTRACT
The telecommunication market in Suriname has been formally liberalized on April 16th 2007. On
that date two new mobile services providers received their license to operate in the market. The
Telecommunicatie Bedrijf Suriname, further to be named Telesur, who had been a monopolist
for 25 years, developed a strategic document in which it laid down how it is to remain
competitive in this new environment. Although strategic, tactical and operational objectives have
been set for the various operating units, no such objectives have been identified for supply chain
management. At present, the supply chain within Telesur is therefore not strategically
exploitable as an instrument for competitive advantage. This research study was chosen to
conduct a case study and develop a supply chain strategy for Telesur. In order to do so the
following problem statement was stated “What is an appropriate supply chain strategy in the
case of Telesur?
A research model was developed and combined with a benchmark study. The model was then
validated within Telesur. The theoretical framework included comprehensive theory on supply –
and logistics management. These were applied to assess which supply chain strategy was
appropriate for the current product groups. Furthermore the maturity levels of supply chain
processes were examined, identifying disconnects related to the case subject’s supply chain
processes.
Validation of theory demonstrates that Telesur should pursue efficiency as a strategy for its
current supply chain. Still, the supply chain process elements PLAN, SOURCE, MAKE and
DELIVER proved to be undeveloped. Furthermore disconnects were identified in the areas of
demand management and forecasting, information integration, supply chain integration of
systems and structures, and performance management. These were all symptoms of immature
supply chain processes. During the research, specific constraints were discovered that have an
impact on these business processes, namely economies of scale and supplier dependence. These
constraints were considered when the supply chain strategy was developed.

warehouses to the end customer (Chase et.all, 2006), i.e. from the point of procurements all the
way to the point of sale to the consumer.
Purchasing: the objective of purchasing is to acquire materials and services of the right quality in
the right quantity at the right price at the right time from the right source (Alan Raedels, 2000).

CHAPTER 1 INTRODUCTION
Section 1.1. Introduction
This case study presents the analysis of the supply chain within Telesur in Suriname. The need for
research became evident after complaints of internal and external customers. Complaints from
internal customers mostly concern a lack of collaborative planning leading to misalignment
between marketing, planning and operations. These were also supported by real cases of mismatch
between demand and supply.
Section 1.2. Preparatory Research
To discover what the main problem at hand was, some preparatory research was done. This desk
research led to the discovery of a dissertation written by the purchasing manager addressing general
problems with purchasing Daal (2007). His research study contained a questionnaire, with the
following conclusions:
� Purchasing can contribute significantly to the performance of Telesur
� The Purchasing Department is not performing well enough to satisfy Telesur’s needs
� The purchasing function needs to be reorganized as soon as possible
� Telesur should have centralized purchasing
� Delivery of the right materials are important
� The Purchasing Department should provide for an uninterrupted flow of goods required to
operate the business.
According to general principles of purchasing, companies must prepare themselves against
disruptions in the supply chain (Kraljic 1983). In an interview with author, the procurement
manager acknowledged that Telesur did not prepare well enough against supply chain disruptions
and meeting customer expectations. Implementation of an Enterprise Resource Planning (ERP)
module could resolve the problems. However, elements of supply chain strategy were not included
in corporate strategy, resulting in the management of disparate parts of the organization rather than
a total supply chain approach. The existing manner of managing the supply chain resulting in the
following symptoms:
2
1. Shortages of equipment at customer premises.
2. Both stock shortages and stock surpluses
3. Lost sales to customers.
Daal (2007) used action research for his case study, for hypothesis testing of what managers that
contributed to the supply chain thought of the role of purchasing. These observations showed that
there are indeed deficiencies within operations and that these usually result in a mismatch between
demand and supply such as shortage of capacity for customer premises equipment. Although these
cases were known to exist among supply chain functions, they were not recorded properly. On the
other hand the research of Daal was only based on the front end of the supply chain, i.e. purchasing,
on which he based his general recommendations. He stated that purchasing must become strategic,
but purchasing was still in a developing phase.
Other documentation included a report of consultant Fernando Kneese (2003). The report’s purpose
was to evaluate the telecommunications company of Suriname and included a segment on the
supply chain process. Kneese (2003) laid down the following deficiencies related to the existing
supply chain. For the purpose of objectivity, his statements were not revised:
1. Lack of trained personnel,
2. Lack of clear technical and functional specifications,
3. Lack of integrated purchase team for the negotiations,
4. Lack of procurement system,
5. Lack of integration with the supply chain,
6. Lack of adequate input from ordering departments or from the budget,
7. Lack of communication between the Procurement department and other departments.
Some additional facts were included in the report:
� The Supply Chain process consists of demand and supply management, procurement, logistics
and warehousing.
� Depreciation costs represent over 33 % of Telesur’s revenue, while procurement costs build up
to 53 % of Telesur’s revenue.
� Demand posed by normal business, operations and maintenance activities make the supply
chain process operationally important.
3
� Finally, he asserted that “Marketing demand and newly developed telecommunications
technologies make the supply chain process strategically important”.
Clearly Kneese illustrated in his report how important the supply chain processes are, however no
clear policies were developed to address the issues with the supply chain. He focused more on
disconnects, but the report lacked a clear understanding of strategic actions to be taken. Although
the disconnects should be turned into opportunities, he did not develop that point of discussion. One
of his main conclusions was that the logistics infrastructure was poor.
Section 1.3. Problem Description
The aforementioned disconnects exemplify the fact that Telesur was not able to adequately manage
and configure the supply chain and lacked clear policies on supply chain management. This gave
reason to question whether a formerly monopolistic company operating in a fully competitive
environment would remain competitive under these circumstances. The main problem at hand is a
lack of supply chain visibility, and of an understanding of how the supply chain could contribute to
the company’s strategic advantage. This led to the following problem statement “What supply chain
strategy is appropriate for Telesur?”
The following central questions must assist in answering the problem statement;
1. What are the appropriate instruments for supply chain analysis?
2. What are the main characteristics of the existing supply chain?
3. What are the supply chain disconnects of Telesur relative to the best practices in the
telecommunications industry?
4. What supply chain strategy can be applied based on the results of the supply chain analysis?
Section 1.4. Scope and Limitations
The research will be conducted in the period September 2007 up to February 2008 and has been
validated for one company only. Another case subject will be studied for benchmark purposes only.
The research study is only based on the external supply chain, thus for the goods and services
obtained for the external customers.

Section 1.5. Relevance of Topic
This case study presents the analysis of the supply chain within Telesur. The findings of this
research are relevant for purchasing managers, operation managers and organizations that are in
need for strategic actions for their supply chain operations.
Section 1.6. Research Model
The foundation of this research framework lies in three models, namely (1) the product portfolio
grid, (2) the Maturity model and (3) the SCOR model. These models are derived from literature on
supply chain management, logistics and supply management. For benchmarking purposes a best-in-
class comparison will be used to assist in identifying the current position of Telesur within the
industry. A combination of benchmark results and application of the aforementioned models will be
of importance to answer the problem statement. Figure 1.0 depicts the methodology.

CHAPTER 2 LITERATURE REVIEW
Section 2.1. Introduction
This chapter describes and discusses related theory on supply management, supply chain
management and logistics management (figure 1.0, chapter 1). The answer will be given to the
following central question “What are the appropriate instruments for supply chain analysis?
First the chapter describes supply management which relates to purchasing and the supply
characteristics of the supply chain. Second, Chapter 2 also discusses what instruments are available
for assessing the existing supply chain of a company. The chapter continues with tools that are used
to assess the level of maturity of supply chain processes. To conclude the chapter, theory is
described that helps determine what a company’s current performance level is compared to the
industry it operates in. The results on literature in this chapter should lead to instruments which can
be used to analyze the existing supply chain of Telesur. In the following section theory on the
evolution will be discussed. In figure 2.0 the highlighted boxes summarize the topics to be
discussed.

Section 2.2. Supply Chain Management Evolution
While conducting secondary research the author came across theory on supply chain evolution.
Supply chain management has evolved over the years from purchasing to a more strategically
important supply chain function. In the 1950’s and 1960’s manufacturers wanted unit production
cost reduction as the primary operations strategy (Tan, 2001). A decade later first materials
requirements planning (MRP) and then manufacturing resource planning (MRP-2) were introduced
followed by intense global competition in the 1980’s. Globalization forced manufacturers to
produce goods and services at lower cost, higher quality, and with greater design flexibility.
Therefore, manufacturers realized the importance of strategic buyer and supplier relationships. Tan
postulated that in the 1990’s the evolution continued with best practices in managing corporate
resources to include strategic suppliers and the logistics function in the value chain. Although his
research findings were only based on manufacturing, Tan (2001) concluded that supply chain
management evolved along two paths. The first was based on a logistics perspective and the second
on purchasing. The one that evolved along the logistics path was based on the transportation and
logistics perspective of merchants. This perspective focused more on location and logistics rather
on transformation. The second one was the purchasing and supply perspective, which included
buyer and supplier integration. Integration of information management systems between buyers and
suppliers should lead to an increase in productivity and reduce cycle times. The ultimate goal of
integration between buyers and suppliers was to increase customer satisfaction and increased
market share. After these two paths Tan discovered a third theory that dominated literature which
was one that describes all value adding activities.
Further research found confirmation in the works of Elram (van Goor, 1999), Gelderman (1983),
and Handfield and Nichols Jr. (2002). First Elram described supply chain management more as
managing and controlling distribution channels in order to achieve customer goals through efficient
maximization of resources. Second, Gelderman’s theory was related to purchasing and supply
management. In one of his journals he stated “Purchasing must become supply chain”. Third,
Handfield and Nichols Jr. (2002) and Jacobs (2006), state that the supply chain encompasses all
organizations and activities associated with the flow and transformation of goods from the raw
materials stage through to the end user, as well as the associated information flows. Material and
information flows both up and down the supply chain. Handfield’s focus is more on value creation
by supply chain integration. Although different definitions have been developed over the years, the
8
commonality between these definitions is that of managing material and information flows from
suppliers to buyers, aligning demand and supply, which in general stays the same. Therefore the
following general definition of supply chain will be used: “the supply chain includes all processes
that put the products in the hands of end users”.
Section 2.3. Purchasing and Supply Management
In this section the importance of purchasing is discussed mainly because it is part of the front end of
the supply chain. Disruptions in the supply chain could be reduced or even eliminated if the
strategic role of purchasing is acknowledged. The objective of purchasing is to acquire materials
and services of the right quality in the right quantity at the right price at the right time from the right
source (Raedels, 2000). The definition of “right” has changed since “purchasing must become
supply management” (Kraljic, 1983). The definition of “right” has another dimension to it because
a value assessment of the role of purchasing today leads to three stages of purchasing (Raedels,
2000). First the traditional purchasing function looks at the price alone. The tactical role of
purchasing then looks at leveraging volume from multiple to single sources. The strategic role,
finally, looks at total value.
Today total value is key to establishing the necessary supply strategy. Kraljic states that the
company’s need for supply strategy firstly depends on the strategic importance of purchasing in
terms of the value added by product line, the percentage of raw materials in total cost, and their
impact on profitability. Other than Raedels he elaborates on the four stages of purchasing
sophistication (appendix 11.0). In his model he states that the higher the degree of market
complexity the greater the importance of purchasing. Supply strategy depends secondly on the
complexity of the supply market gauged by supply scarcity, pace of technology, monopoly or
oligopoly conditions, entry barriers logistics cost and materials substitution.
Given these theoretical facts, it is to be stated that the strategic advantage of the supply chain
depends on the phase in which purchasing exists.
9
Section 2.4. Internal and External Supply Chains
Supply chain management distinguishes internal and external supply chains. Elaborating further on
Handfield’s and Nichols Jr.’s (2002) definition of supply chain integration, it is important to
distinguish value creation by internal organizational members and external stakeholders. In their
book Supply Chain Redesign, they made a distinction between internal and external supply chain,
which differs from Elram and Stevens (van Goor, 1999). An internal supply chain is a part of the
supply chain occurring within an individual organization. According to Handfield and Nichols,
internal supply chains are complex, since different types of strategies and organizational structures
require different supply chain configurations. These are dependent on the types of goods and
services which they deliver. Once the internal supply chain is understood, the analysis will extend
to the external part of the supply chain. External supply chains consist of suppliers and end
customers.
This study is limited to the goods and services provided to the external customers.
Section 2.5. Supply Chain for Strategic Advantage
Organizations can develop or improve their competitiveness by bringing “supply chain thinking”
into their company strategy. Making supply chain management strategic means aligning all
operations and information systems with company strategy (Ayers, 1999). In his article Ayers
proved how supply chains can become strategic, based on the dimension of demand characteristics.
Demand characteristics are based on product functionalities which have been determined by the
consumers. He elaborated further on themes of Marshall Fisher and Michael Porter (Ayers, 1999)
and he used their portfolio model to prove how demand characteristics are fundamental for supply
chain strategy (figure 2.0). This resulted in the Product Positioning Grid.
Section 2.5.1. Supply Chain Strategy Assessment
The main objective of the Product Positioning Grid is to help analyze what supply chain strategy is
appropriate for an organization depending on the products it sells. Ayers explained how this
assessment should take place. The Product Positioning Grid is a framework that assists managers in
10
understanding the nature of demand for their products. Based upon the product functionalities a
supply chain that could best “fit” that demand would then be developed (Chase et al., 2006). The
model consists of characteristics such as product life cycle, demand predictability, product variety
and lead times of services.
Ayers explained that products are categorized either as being functional or innovative making it less
difficult for managers to understand the nature of demand. Functional products have longer life
cycles, with low contribution margin, whereas innovative products have shorter life cycles of only
few months. This framework determines product competitiveness by the supply chain that delivers
the product. The foundation of the product grid lies in its functionality, reliability and value-for-
money (Figure 2.1.). The framework is interpreted as follows:
Quadrant A in the grid is categorized as products being best in class performers with excellent
supply chain processes. C is categorized as products being sold in a market where competition is
intense with little difference amongst these products. Supply chain innovation is required to
compete in the market, since these products are no longer the standard for product excellence. B is
categorized by products that are nearly at the end of their product life cycle, with inefficient
operations. Products categorized as D products on the left side are at the end of their life cycle.
Organizations must pursue the position of product group A, making them products with excellent
products and supply chains.
FIGURE 2.1. The Product Positioning Grid

11
A and B are categories equivalent to innovative products and Porter postulates that these product
categories command higher contribution margins, requiring supply chain design based on
availability (Ayers, 1999). Product categories C and D match functional products, requiring
efficient supply chains with low contribution margins. To conclude this segment it is to be stated
that the application of this grid leads to identifying the appropriate supply chain strategy of an
organization.
Section 2.5.2. Supply and Demand Characteristics
In addition to the Product Positioning Grid, Hau Lee (Chase, et. all 2006) describes the supply
dimension for devising a supply chain. Lee’s framework, which is also portfolio based, expands on
Fisher’s demand characteristics as stated by Ayers and underlines the supply dimension with the
same. He describes supply chain strategies that mitigate risk as follows (figure 2.2):
FIGURE 2.2. Demand Uncertainty Matrix
Source: Operations Management For Competitive Advantage
� Efficient supply chain strategies: strategies aimed at creating the highest cost efficiency,
eliminating non-value added activities, and deployment of optimization strategies.
� Risk-hedging supply chain strategy: strategies aimed at pooling and sharing resources in a
supply chain so that the risks in supply disruptions can be shared.
12
� Responsive supply chain strategy: strategies aimed at being responsive and flexible to the
changing and diverse needs of the customers.
� Agile supply chain strategy: strategies aimed at being responsive and flexible to customer
needs, while the risks of supply shortages or disruptions are hedged by pooling inventory
and other capacity resources. According to theory they are agile since they have the ability
to be responsive to the changing diverse and unpredictable demands of customers and
minimize supply chain disruptions, reducing risk both at the front end and the back end of
the supply chain.
However in companies where processes have not evolved into mature stages, hedging and pooling
to a certain extent, could lead to increased supply chain disruptions. For example, pooling on each
others’ stock could also mean that one business unit has not properly planned its material
requirements, which could lead to a bullwhip effect1. The latter could have negative implications for
customer service. So in this research another interpretation applies: Agile supply chain strategies
should lead to shortened response times and production flexibility.
Lee (Chase et al., 2006) states that it is more challenging to operate an organization with a supply
chain strategy that is in the right hand side of the grid. Similarly it is more challenging to operate a
supply chain that is in the lower row (Figure 2.2). He determined that the supply chain will improve
if the uncertainty characteristics of the products are moved from the right column to the left or from
the lower row to the upper by standardizing supply chain processes. In addition to the Product
Position Grid organizations need to include Lee’s Demand and Supply Uncertainty Matrix to assess
their existing supply chain strategy.
Section 2.6. Supply Chain Optimization
In the previous section instruments have been discussed which can be applied to assess an
organization’s supply chain strategy that best fits according to product and demand characteristics.
Knowledge of the most appropriate strategy is not sufficient though, because it only says something
about where the organization is leading its business practices to. Yet an organization must assess if
1 The Bullwhip effect is caused by fluctuations in demand, which as a result is causing stock shortages to become stock
overs.
13
the supply chain processes of the organization have been sufficiently developed to lead the
company towards gaining competitive advantage. This is a question of whether the organization has
the capabilities to govern its supply chain processes according to the strategic objectives.
Section 2.6.1. Supply Chain Maturity Model
Literature study led to theory on the Maturity Model, which was described and applied by
McCormack and Lockamy (2004). Both state that companies reach greater levels of performance
when they focus strategically on their business processes. This was also the foundation for
McCormack’s research on the Maturity Model. This model assesses the supply chain processes and
produces results on which strategies for organizations to move from poor supply chains processes to
best in class (Figure 2.2). The model conceptualizes how process maturity relates to the Supply
Chain Operations Reference Framework, which will be discussed further in section 2.6.2. The
method used to obtain the aforementioned result is usually through surveys. In this research study it
will be applied to assess the case subject’s stage of maturity.
In another journal, McCormack stated that the model is not directly related to supply chain
processes but encompasses components related to the definition, measurement, management and
control of business processes in general (McCormack et al., 2007). The maturity model is a tool
which is used to investigate the relationship between supply chain process maturity and overall
supply chain performance. The model consists of five stages, describing an organization’s growth
towards effective processes and process maturity. With each level of maturity comes an increasing
level of predictability, capability, control, effectiveness and efficiency.
The first stage depicted in the model is “Ad hoc”. Ad Hoc is characterized as an unstructured supply
chain, without clear targets and process measurement. In the second stage “Defined”, process
performance is more predicable, but often the organization does not achieve defined targets. At both
previously described stages supply chain cost are high and job function traditional. The next stage is
“Linked”, linking processes and functional team members to each other sharing common goals and
making a supply chain more strategic. Supply chain costs begin decreasing slightly, and targets are
often achieved through performance measurement systems.
14
FIGURE 2.3 The Maturity Model
Source: McCormick 2006
The fourth stage “Integrated” is an integrated approach towards supply chain management, based on
clear performance measurements, advanced supply chain practices and a collaboration between
suppliers and customers that leads to collaborative planning and forecasting. McCormack concludes
with the fifth phase, which is named “Extended or Evolved”. Extended is client focused and is
based on multi-organizational supply chains, with extended processes and recognized authority
throughout the supply chain. McCormack emphasizes that skipping stages is counter productive, for
as each stage is a building block for the next.
If application of the Maturity Model results in the identification of less developed processes then
the next step is to determine what the underlying causes are and what the implications could be for
the business processes in question. Other steps should be how these disconnects could be removed,
leading to improvement and optimization of the processes from for example “defined” to
“integrated”. To assess what disconnects relate to the supply chain processes and how optimization
should take place the Supply Chain Operations Reference model (section 2.6.2) is applied.
15
Section 2.6.2. The Supply Chain Operations Reference (SCOR) Model
In this section the Supply Chain Operations Reference Model will be discussed giving more
insights into how supply chain processes can be optimized. The Supply Chain Operations Reference
model, further to be named “the SCOR model” was developed by the Supply Chain Council and
became relevant to this study because it provides an integrated, disciplined approach for supply
chain optimization. SCOR utilizes a business process reference model that links process description
and definition with metrics, best practice and technology (Elram et al, 1999; see also appendix 1).
SCOR is part of the Integrated Business Reference Model consisting of Design Chain Operations
Reference Model (DCOR) and Customer Chain Operations Reference Model (CCOR). Worldwide
almost 750 companies, mostly American based organizations, use the SCOR model for supply
chain optimization. The model is built around five distinct process groups: PLAN, SOURCE, MAKE,
DELIVER and RETURN. The Supply Chain Council defined the processes as follows:
1. PLAN; are processes that balance aggregated demand and supply to develop a course of action
which best meets sourcing, production and delivery demand.
2. SOURCE; procurement of goods and services to meet planned actual demand.
3. MAKE; these processes include manufacturing of goods to the desired state to meet actual
demand. Some organizations find it difficult to visualize and measure a services supply chain
(Swartwood, 2006). The author therefore asserts that MAKE includes the workflow combining
the goods and labour that will finally result in a service.
4. DELIVER; these processes are used to provide finished goods and services to meet planned or
actual demand. Functions related to this process are distribution management, transportation
management and order management. Referring to Swartwood, delivery of services is a
combined effort of human capital and goods.
5. RETURN; processes related to receiving returned goods.
The research study will be limited to the first four relevant processes PLAN, SOURCE, MAKE and
DELIVER at level one, given the relevance for the case subject. By definition there are no RETURN
processes when services are concerned. Level one refers to the first level of process description.
Since strategy development is the main focus, the other levels for example level two, three, will not
be described in this research study.
16
FIGURE 2.4 SCOR Process Elements
The SCOR approach contains elements that are based on basic benchmark steps. Handfield and
Nichols Jr (2002) cite Cook who postulates that benchmark analysis contains an effective means of
determining the supply chain performance compared to those of other organizations. Comparing
practices and procedures from other businesses to the best in class helps identify the necessary
improvements to be made. SCOR is based on these general seven steps for benchmark analysis.
Figure 2.4 depicts the staircase which is in this research is named the SCOR benchmark staircase
for supply chain optimization. The same benchmark staircase will be applied, instead of the original
model because of the lower degree of complexity.
FIGURE 2.5 General Benchmark Stair Case
Source: Supply Chain excellence (2003), Supply Chain Integration (2002)
The benchmark staircase will be used combined with some elements of the original SCOR model.
In each stage of benchmark the elements will be described. Application of SCOR should result in
detecting strategy drivers:
Identify As Is situation
The As Is analysis uses SCOR elements to describe the existing situation of the company which
are:
17
� Description of internal and external profile, which is used to describe the scope of
business. Internal profile first looks at the organization chart, then at the identification of
all locations in operation.
� SWOT; using a simple strengths, weaknesses, opportunities and threats analysis a better
understanding exists of the current state of business using the external and internal
profile.
� Identification of suppliers and customers using the 80/20 rule. Suppliers are categorized
by the amount of capital spent, while customers are categorized by the company’s
related earnings.
� Identify As Is material and information flow. The second step of the SCOR framework is
process mapping of existing material flows from suppliers to customers. After mapping
these processes a performance spreadsheet is developed measuring the company’s
performance in each of the four processes, PLAN, SOURCE, MAKE and DELIVER. An
organization’s material flow is accompanied by an information flow, which according to
the SCOR model consists of six SCOR level three transaction types. The third phase of
SCOR model maps the information flows, which are purchase order, work order, sales
order, return authorization, forecasts-plan and replenishment orders. In general the
purchase orders move through:
� S1.1 Schedule product deliveries,
� S1.2 receive product
� S1.3 verify products
� S1.4 transfer product
� S1.5 authorize supplier payment
The SCOR uses the “Staple yourself transaction analysis”, that has the objective to collect data
from the existing supply chains material flow. Each movement is followed physically from the
moment its starts until the moment it ends. This is measured by performance indicators
“technology” and “productivity”. Technology refers to the information tools utilized to complete
the tasks identified in the process step. The next three items on the worksheet are factors in
calculating transaction productivity. Productivity refers to three simple metrics: volume, cycle
time and yield.
� Volume is the number of transactions of the primary output over a specified period of time.
18
� Cycle time is defined in two ways. Event time is the time spent on the tasks from start to
finish assuming no lag time. Elapsed time is the actual time that passes from start to finish
including any lag time; for instance it could take a material handler one hour to complete all
four tasks without waiting time, but four hours in elapsed time.
� Yield is the number of transactions requiring no rework. It is measured as a percentage of the
total. This concept places a value on purchase, work and sales orders that need to be
reopened to change or complete data, such as bad addresses, incorrect unit prices or terms,
wrong quantities.
The “As Is” analysis is summarized in a performance spreadsheet of which the objective is to
collect and analyze key SCOR level two metrics for each location. Supply chain metrics are
exemplified by Bolstorff and Rosenbaum (2003) and summarized in appendix 4.0.
2. Determine what to benchmark
Bolstorff and Rosenbaum explain that measuring an organization’s supply chain does not only
mean measuring KPI’s that are important to internal stakeholders, but also important to
shareholders and end customers. They state that based upon this assumption a SCOR card matrix
must include performance measurement indicators relevant to customer, shareholders and the
internal organization. The indicators under which the organization is benchmarked against best in
class are for example availability and delivery performance. As mentioned before, an explanation of
these metrics are summarized in appendix 4.0 followed by a brief explanation. Application of this
framework should result in the mapping of existing processes and in visibility of disconnects
between processes.
3. Determine benchmark partners
The SCOR card is an instrument which provides such useful comparison. It produces metrics
for the company that is then compared against the industry’s SCOR card, determining the
organization’s current competitive position. Competitiveness is determined by positioning an
organization at three levels namely a level of advantage, a level at parity and a superior level.
Statistically the gaps between the three levels can be measured by calculating the parity gap and
the competitive requirement gap. The parity gap is the gap between the industry’s average and
the company’s actual performance. The parity gap is measured by subtracting the actual
performance of the company from the industry’s average. The competitive requirement gap is
19
the gap between the actual performance of the company and the best in class performances. If
the comparison results in a disadvantage, then these are presented as negative values. The result
of this methodology is the foundation for determining the organizations strategy driver.
The abovementioned benchmarking steps are the only ones to be used in this chapter. The other
four steps are relevant for chapter 5 where the research results will be presented. In this chapter the
information gathered from questionnaires will be discussed. Improvements relative to the
benchmark will also be presented.
To conclude this segment, literature reviews of SCOR have in general been positive; however the
SCOR model contains limitations;
1. Dan Swartwood’s adaptation of SCOR (2006) proved the model to be normative for industrial
companies. The commonality between manufacturing and services supply chain is the degree of
certainty in the chain. Application of the model in a services company may be hampered by the
complexity of multiple supply chains. The input of the supply chain might differ depending on
the desired outcome, for example for education the output is intellectual. This proved to be a
limitation.
2. SCOR does not specifically address sales and marketing (demand management), or research and
development, or product development. If the research discovers problems in demand
management, further research is needed.
Section 2.7. Decision Making Framework
In this section all relevant theory described in the previous sections will be contextualized in a
decision making framework. Before doing such, first two factors will be described that influence
the decision making process leading to the appropriate supply chain strategy.
The first factor that influences strategy development is related to supply management. Kraljic
(1983) used the comprehensive portfolio matrix to reduce supply vulnerabilities. He explained
volume to be the main determinant of a company’s bargaining power, because economies of scale
yield a decisive competitive cost advantage. For companies with fewer economies of scale, high
supplier dependency would apply. Second, the author will refer to McDonald (2006) who adapted
20
the Kraljic purchasing portfolio model to remoteness. McDonald proved how Kraljic’s portfolio
model applies to industrialized countries. He cited Nellore and Söderquist (2000), who rationalized
the purchasing portfolio dimension as being experience based. Poor logistics, economies of scale
and remoteness will be considered during strategy development.
The second factor relates to ownership. Literature research on supply chain management does not
specifically address corporate ownership as a factor yielding risk. In the 20th century a redefinition
of the role of the government was needed to expand industrial activity (Jayashankar, 2007).
Jayashankar explains that the government should perform the role of facilitator and companies need
to endeavor a strategic management approach.
The abovementioned factors are included in the decision making framework which will be used to
lay down the organization’s status quo and develop an appropriate supply chain strategy. The
framework contains the Product Positioning Grid (cf Section 2.5), the Maturity Model (cf Section
2.6.1) and the SCOR model (cf Section 2.6.2). For the Product Positioning Grid the product life
cycle, contribution margin and product functionalities determine the supply chain strategy that best
fits an organization. This is necessary for organizations that have never made their supply chain
visible. When visibility is realized then the Maturity Model is needed to determine the stage of
development for supply chain processes. The results of the maturity model are then used to
determine how this affects operations. Finally, the SCOR model then assists in identifying
disconnects. Disconnects which could affect strategy development and execution.
In the end the framework must lead to pursuing the existing supply chain strategy which has been
determined using the Product Positioning Grid. Other actions of an organization could for example
also lead to a change of strategy. In conclusion an organization must consider the factors related to
the decision making framework in order to develop a supply chain strategy that best fits its overall
business strategy.

Section 2.8. Summary
The objective of this chapter was to provide an answer to the central question “What are the
appropriate instruments for supply chain analysis? To answer this question literature was reviewed
on the evolution of supply chain management as a science. Supply chain management evolved
along three paths, namely logistics, supply management and value creation. Literature also revealed
two dimensions to the supply chain, the demand and the supply sides, that are fundamental for
strategy development. The demand side looks more at the demand characteristics of products. The
supply side on the other hand looks more at mitigating supply risk. The Product Positioning Grid,
the Supply Chain Maturity model, and the SCOR model are appropriate tools to determine a
foundation on which a supply chain strategy is developed. The Product Positioning Grid determine
which supply chain is appropriate for business, given the services provided to the market,
categorizing products as functional or innovative. Applications of their models induce strategic
actions for organizations. The maturity model assesses the current stage of supply chain processes,
while SCOR identifies disconnects in the existing supply chain. Reviewing these models, it became
clear that they are all limited in certain cases. They are normative and apply for industrialized
countries; adaptation is required for specific cases. Factors related to supply management and
ownership were added to a developed decision making framework.

CHAPTER 3 RESEARCH METHODOLOGY
Section 3.1. Introduction
In this chapter the methodology is described that was used to systematically answer the problem
statements. Guidance for this research study was obtained from literature by Piet Verschuren and
Hans Doorewaard. The methodology must result in strategic directions for the case object.
FIGURE 3.0.Topics Related to Chapter 3
Section 3.2. Definition of Research Problem
The main problem of the case subject is that the supply chain strategy is unclear. The characteristics
have not been laid down properly and also disconnects have not been identified. The research
subject, Telesur, is therefore unable to use the supply chain strategically as an instrument to gain
competitive advantage.
Section 3.3. Definition of Research Purpose
The purpose of this research is to develop an appropriate supply chain strategy and determine the
current state of the supply chain state. Visibility of the existing supply chain also remains an
objective.
23
Section 3.4. Definition of Research Strategy
A sequential case study is required to answer the central questions, studying first the case subject
and then selecting a best in class subject for comparison. Given the time constraint only one
research subject was included. Literature will be combined with practice using input from cross
functional staff. The staff members are directly related to the case subject’s supply chain process
elements PLAN, SOURCE, MAKE and DELIVER. Using inductive comparison a supply chain strategy
will be developed based on the research results. First, the main observations such as supply chain
disruptions and performance management will be validated using interviews. This will be followed
by testing against a larger sample size, the information gathered from the one on one interviews.
The sample contains 16 employees from 9 departments. The same selected staff members serve as
sources of information from questionnaires and information related to material, work and
information flow.
Section 3.5. Data Collection
Primary information will be collected through interviews and observations. Secondary information
is available using existing documentation as laid down in chapters 1 and 2. The involvement of the
cross functional members is essential, for as the research progresses they will be learning by
implementing. The members will be appointed supply chain agents, communicating the objectives,
the acquired results and contribution and role to this study, to their subordinates. Except for other
information in this research, financial figures were used from the year 2006 as the most recent
available figures.
Section 3.6. Application of Instruments
Understanding the current supply chain characteristics requires a thorough analysis, applying the
theoretical framework described in chapter 2. First the Product Portfolio Grid will be used to
identify which supply chain strategy is required for each of the product groups. Second, the
assessment according to the Maturity Model will depend on the following criteria: state of process -
structures, availability of key performance indicators and of functional descriptions.
24
To find out if the above described criteria apply to the organization’s supply chain, data will be
obtained from a survey amongst cross-functional team members. Gathering information for SCOR
model application is the most difficult since the customer related metrics have not been measured.
To determine the scope of business, information for the SWOT analysis has been obtained from
recent company analysis from 2006 to which different organizational members have contributed.
Material and information flows will be mapped using information obtained from described
processes, interviews, observation and, where available, documentation, together with the cross
functional team members. Where there are no defined measurement systems, a number of
assumptions will be made.
Section 3.7. Interpretation of Results
The most important dimension of this research is the interpretation of results which could lead to
unexpected conclusions, i.e. conclusions that differ from internal organizational members’
perceptions of supply chain functions such as purchasing, marketing, sales and planning. The main
research recommendations could also differ from proposed solutions by organizational members
mentioned in other documentation. On the other hand, there could be similarities in findings.
Findings presented to cross functional team members must result in an evaluation of their existing
role in the supply chain and what strategic actions should be taken, given corporate strategy. The
cause and effect exercise will be beneficial to all team members giving them authority to present
conditions under which actions must be taken.
Section 3.8. Summary
This chapter describes each processes needed to ensure an answer to the research problem. The
process steps include observations of symptoms related to the supply chain. First literature of
logistics and supply chain management will be reviewed. This is followed by interviews of staff
responsible for supply chain process elements PLAN, SOURCE, MAKE and DELIVER. A cross
functional team will assist in to gathering information to answer the problem statement. The
findings will be the foundations for recommendations, which will be shared with organizational
stakeholders.

CHAPTER 4 BUSINESS CONTEXT
Section 4.1. Introduction
Chapter four gives a general description of Telesur. First a company overview will be described
presenting the company’s financial status. The necessity of supply chain development becomes
clear in this chapter because of the changed strategic direction that is laid down. The changed
conditions in the mobile telecommunications market which are also described in this chapter,
illustrate how fierce competition is in Suriname and why Telesur needs to gain a competitive
advantage.
FIGURE 4.0. Topics Related to Chapter 4.
Section 4.2. Company Overview
Section 4.2.1 Company Profile
Telesur is the first telecommunications company of Suriname and employs about 1100 people. The
company contributes almost 6 % to the Gross Domestic Product2 and provides connectivity to an
estimated 80,000 residential customers. The government is sole shareholder and Telesur is currently

process of changing the legal status of the company from Sui Generis3 into a Limited Liability
company. Telesur is structured in four divisions namely operations, commercial, financial and
logistics affairs (appendix 2.0). It has seven regionally spread sales branch offices. The company’s
product portfolio consists of three major product groups which include
1) Data communication Services.
2) Fixed Telephony and Mobile Services.
3) Internet and Multimedia Services.
4) ATV which also generates revenue is a television company.
5) Other services include total solutions for some company’s.

27
Section 4.2.2 New Identity and Strategy
In 2006 the company changed its strategic direction which gives general guidelines for transforming
the company from a monopolist to a market driven company (from reactive to proactive). In this
strategic plan the scope of business expanded slightly, because markets were not only defined as
local and regional, but also in the Dutch speaking market. In the Dutch speaking market, primarily
the Netherlands, an estimated 300.000 inhabitants from Surinamese descent are domiciled. To
elaborate further on the strategic directions, the company established three themes namely
innovation, cost reduction and quality improvement. The themes evolve along convergence where
services are deployed based on one network solution (Ericsson White Papers, 2006) improving the
organization’s efficiencies and cost effectiveness.
Section 4.3. Competitive Environment
In 1997 the Surinamese government committed itself to the liberalization of the
telecommunications market, because it signed off on telecommunications treaty established by the
World Trade Organization. On the 16th of April 2007 both Digicel and Intelsur received their
licenses to operate in the Surinamese market as telecom operators. Digicel is a private owned Irish
company with 23 branch offices spread across the Caribbean, Mid America, and Pan American
region. Intelsur is a partner of partly state owned UTS, a company that operates in Curaçao as the
incumbent.
Moreover, in this changing market environment pros-umption4 and immediacy5, both reflecting
customer buying power, are becoming the main market drivers.
4 Don Tapscott (1996) explained that customer’s involvement increases in the production process increases; he coined
the word prosumption by contracting production and consumption. 5 Tapscott, (1996) states that, the economy is becoming a real time economy. Businesses must immediately adjust to
changing business conditions and customers needs.
28
Section 4.4 Summary
In the previous chapter background information of Telesur was laid down. The scope of business
was described and the product groups which are deployed in Suriname. Telesur faces competition
on mobile communication services leading to a changed competitive environment, with customers
becoming increasingly demanding.
29
CHAPTER 5 RESEARCH FINDINGS
Section 5.1. Introduction
In order to answer the second central question “What are the current characteristics of the existing
supply chain?” the methodology described in chapter 3 was followed. This chapter first assesses
what supply chain strategy best fits Telesur using the Product Positioning Grid. Second the Supply
Chain Maturity model is used to identify what the current maturity level of supply chain processes
is. Third the SCOR model is applied to identify what disconnects exist within the Telesur
organization. To conclude this section a benchmark study between T Mobile and Telesur is
presented, giving insight in to how disconnects could be removed using best practises from T
Mobile. The current supply chain characteristics are then summarized in this chapter.
The results presented in this section are based on a collaborative effort of a group of organizational
staff members, directly related to the supply chain activities. These cross functional staff are from
Marketing, Purchasing, Planning, Stock management and Sales, joined by the supply chain
representative from T Mobile. T Mobile and Telesur have a long lasting agreement for mobile
roaming services in the Netherlands.
FIGURE 5.0 Topics Related to Chapter 5

Section 5.2. Assessment of the Existing Supply Chain Strategy
Using the Product Positioning Grid, as presented by Ayers in chapter 2, the existing supply chain
strategy will be determined. The product positioning grid assists in understanding the nature of
demand and identifying the most suitable supply chain for that demand (Ayers, 1999). According to
Ayers the positioning of the products is dependant on the product life cycle, contribution margin
and product functionalities. Based on these factors it is to be concluded that the product groups are
in the stage of maturity in the product lifecycle. Information on the contribution margin remains
aggregated so the author will assume that contribution margins are low. The products are therefore
classified as being functional. An explanation will be given on what these conclusions are based
upon.
The product groups under consideration for this study are Fixed Telephony including Mobile
Services, Data Services and Internet services. These were selected based on their aggregate revenue
generation – representing over 95% of total Telesur revenues - and growth rates depicted in chapter
4, segment 4.2. The revenue growth rates of these product groups were then obtained from the
annual report 2006 and the results were as follows.
First, one can look at year-on-year revenue growth of each of the product groups, in order to
determine its stage of product life cycle. Graph 5.0 which depicted the results showed no clear
pattern. These facts were not enough to state in which stage of product lifecycle the product groups
are.
Additional market information proved to be helpful;
� If product development were to be considered then it is to be concluded that the level of
product development is low for product group A. As the Fixed Telephony technology is
stable, any product development has been limited to offering additional value added
services, which Telesur launched 4 years ago. By the same token however, for product
group A, which also includes Mobile Services, important functionalities have not been
utilized to the fullest, such as internet on mobile. This brings into question whether mobile
services can still be regarded as being innovative for the Surinamese market. Since one of
the competitors utilized a full fledged internet on mobile service, the level of innovativeness
remains a point of discussion. Both product groups are therefore positioned as being
31
functional. For Data Communications services (group B) there were no major developments
to improve or innovate these type of services. For 4 consecutive years lease lines have been
the revenue generator for product B. This group is also classified as functional.
� Product group C, Internet Services, experienced an explosive growth of revenue in 2006
compared to 2005 and 2004, but grew less in 2007 compared to 2006. Other than ADSL
there were no major developments on product innovation, which led to the conclusion that
product group C is also classified as being functional. In graph 5.0 shown below the year on
year growth rates have been presented.

According to the product positioning grid, group A, B and C would be positioned based on the
criteria product life cycle, product functionalities and contribution margins. It is to be concluded
that because of the low level of product innovation, the risk still exists that these service offerings
have reached maturity.
The information gathered from graph 5.0 can only serve to assess product excellence. To say
something about supply chain excellence would require information about metrics such as
availability or lead-time for all product groups. Since the availability of information is not
sufficient, the results contained in the maturity model in section 5.3 were considered. Next to the Y
axis in figure 5.0, the values 1 to 5 on a Likert scale have been laid down.
32
Product categories A, B and C are positioned as and are equal to functional products, because of
their modest revenue growth rates and product innovation. Using Hau Lee’s supply and demand
risk framework combined with the product-positioning grid, mitigating risk for all product groups
would require efficient strategies. Fixed telephony for example would now require standardization
of processes in order to reduce cost and remove all non-value adding activities. If one of the product
groups would encounter innovation for example, it would require an agile supply chain strategy.
FIGURE 5.1 The Product Positioning Grid
Depending on the outcome, one could assume that an efficient supply chain strategy might be
appropriate for all product groups. To further investigate what the level of supply chain excellence
is with related disconnects of Telesur’s supply chain, application of the supply chain maturity
model is required.
Section 5.3. The Supply Chain Maturity Model of Telesur
The supply chain maturity model was validated performing a survey amongst staff members of key
supply chain functions namely marketing, purchasing, integral planning, sales, stock management,
data communication services. The questionnaires were first translated into Dutch to remove the
33
language barrier that could lead to misinterpretation for respondents. These numbers represent the
supply chain maturity stages for Telesur as assessed by the interviewees.
Based upon the respondents’ answers, it is to be concluded that Telesur’s is in early stages of
supply chain maturity. The company’s average process maturity is between level of Ad Hoc and
Defined. Process element PLAN scores relatively higher compared to the other process elements and
SOURCE (purchasing) relatively lower, which is similar to what the research of Daal (2007)
concluded. Figure 5.2 depicts the results.
From the information obtained from the Telesur’s respondents it is to be concluded that they have
little or no knowledge of performance metrics and there lacks a total supply chain approach.
FIGURE 5.2 Maturity of Supply Chain Process
Source: Questionnaire Supply Chain Maturity process
Some of the questions were not answered, mainly because they were not relevant to the
respondents. A paradigm was also identified concerning regarding process documentation and
process measurement. Processes were documented but departments failed to measure them. Yet,
measurement of processes should be one of the reasons for documenting and defining processes. An
explanation of the distinct process elements will follow.
PROCESS ELEMENT PLAN
The total average score granted by 16 staff members, was valued at the level between “Ad Hoc’and
34
‘Defined’ on a 5-point Likert Scale (appendix 10.0). Where the forecasting models were available
to test the forecasting processes, the minimum average of 1,6 was granted. Respondents
acknowledge that much attention was paid to the planning process of workflow. However, because
ad hoc activities remain, postponement of planned execution of objectives extends the planning
process. For example supply chain disruptions occur when promotional activities are planned on a
day to day basis. Another example is about an ADSL promotional activity which was planned at the
annual fair in 2007. The supply chain was unable to support the subsequent increased demand on
short notice. This resulted in relocation of customer equipment, because they supplied customers
according to the last in first out (LIFO) principle. The previously described example is a symptom
of insufficient cross functional planning. The score of 1,9 was the second lowest score when
respondents were asked if cross functional planning methodologies were structural.
PROCESS ELEMENT SOURCE
Examining centralized purchasing was one of the main objectives of this part of the questionnaire.
Respondents confirmed that they did not involve the purchasing department in the supplier selection
process. The lower values for purchasing activities were given because clear supplier performance
indicators were missing. For the respondents that did in fact make supplier agreements, and in the
process involved purchasing, the values were also poor. Again, process measurement did not exist.
Scheduling processes between suppliers and Telesur were neither defined nor measured.
Agreements between Telesur and their suppliers about for example penalties for delayed supplier
deliveries do not exist at the moment. This was confirmed by the questionnaire responses.
Integration of the systems between Telesur and their suppliers did not exist, as proved by the
questionnaire. The latter led to a lower process maturity stage.
PROCESS ELEMENT MAKE
This is the production part of the supply chain. The MAKE part is a collaborative effort between
departments, to transform equipment, capacity and end customer equipment into end customer
services. These processes are at a relatively higher level of maturity. The lowest value is given to
the question whether material requirement planning models and systems exists. The respondents
gave a relatively high value to the statements whether their processes are aligned with other
departments’ processes. However, alignment must not be interpreted as a collaborative process, but
more as one that is based on requests from departments. This is justified by an average score of 1,8
for the statement whether the processes are based on cross functional collaboration.
35
PROCESS ELEMENT DELIVER
DELIVER is at a relatively lower stage of maturity. One would assume from the value of 2,0 given
for the statement whether departments can deliver more than is requested, that processes are
streamlined. The latter is not a result of streamlined processes, but of excess capacity. A case
example for mobile services will follow in chapter 5. Results show that performance measurement
systems undeveloped. Performance indicators remain to be defined for the supply chain sections
from suppliers to Telesur, and from Telesur to end customers. The results present a score of 1,8,
measuring the process maturity of DELIVERY. In conclusion distribution processes are not clearly
defined and documented, which represent the low average score 1,9.
The outcome gave cause to compare the information gathered from respondents with Telesur’s
process network architecture. The process network architecture is a guideline used by Telesur for
the strategic direction with related processes defined at level one. The comparison provided
information about the low level of process maturity.

An estimated 17 % of processes have been defined and documented at level two. The remaining
83% are still to be defined. To ensure customer service improvement, Telesur is obliged to
prioritize those remaining process definitions. Based on the company’s snapshot of existing process
maturity, improvement is still an opportunity. Organizational members have explained that
processes are under “construction” and will be defined on short term. However a process
description is no guarantee for supply chain optimization, process owners remain the ones who
manage and control them.
Section 5.4 The SCOR model Applied within Telesur
36
In the previous segments the characteristics of the process maturity of the supply chain have been
laid down. To further detect disconnects, the SCOR model will analyze the company from a
different dimension. The same staircase will be used for this part of the analysis. The analysis will
result in the identification of strategy drivers for supply chain optimization.
Section 5.4.1. As Is analysis using SWOT
To begin with, the first step of the SCOR framework is to define the organizational scope of
business. The author conducted performed a general Strengths-Weaknesses-Opportunities-Threats
(SWOT) analysis based on the external and internal company profile. This SWOT was combined
with recent SWOT analysis results conducted by Telesur:

Section 5.4.2. As Is Analysis for Material and Information Flow of Telesur
5.4.2.1. Supply Chain Definition Matrix
The second step of SCOR is to define the supply chain by its markets, market segments and
distribution channels. In the first section the positioning of services in the Product Positioning Grid
determined the presumed supply chain strategy based on the existing product functionalities, life
cycles and contribution margins. Supply chain definition is contextualized as the supplier base, the
customer base, the product groups, the market and the work and information flow. Table 5.2
exhibits three basic product groups described earlier in chapter four, indicating the market segments
to which they are deployed The 20/80 rule applies for the company’s customer base: 20% consist of
the high revenue generators which are depicted in table 5.2. For reasons of confidentiality the
financial figures are not exhibited.

Telesur’s front end of the supply chain is composed of geographically positioned suppliers from for
example the North American continent, Europe, Asia, the South American continent. Based on the
80/20 rule the top 20 suppliers from 2006 and 2007 selected from a list of 97 suppliers, in terms of
annual spend, have been identified and are presented in table 5.4. The total procurement costs make
up an estimated 38% of the total cost of goods sold. The majority of suppliers originate from the
North American and the European continent, illustrating the importance of related import duties
that in general ad up to 50%.
27,6 % of the current procurement costs has been spent on Nortel. The latter illustrates the supplier
dependency and longer lead times, because geographically a large distance exists between
continents South America, North America and Europe. Process elements PLAN, SOURCE, MAKE and
DELIVER are utilized, not only for engineer-to-stock products but also for finished stock.

Section 5.4.2.2. Work and information Flow
The mapping of suppliers, distribution channels and customers, is followed by the general material
and information flow at level one. Appendix 3.0 depicts the relevant flows.
(a) Identify benchmark partners and determine what to benchmark
In order to establish a snapshot of Telesur’s performance, a benchmark comparison will be made.
To better illustrate the companies performance compared to the industry, the same proposed metrics
40
by Bolstorff and Rosenbaum (2003) have been selected. For the customer facing metrics no data
was obtained, which gave reason to leave the rows in table 5.4 grey coloured. First a selection of 10
of the top 20 telecommunications companies world wide (ITU, 1997) to gain a snapshot of the
industry’s best in class. Forbes and Fortune 500 were also considered to obtain knowledge about
the current status of the benchmark company’s, since the ITU reference is outdated. Industry data
has been obtained from this public owned company’s registered at Hoovers.com. preferably the
author would compare the companies within the region (Caricom), but due to availability of
parameters these company’s were used. The metric definitions are contained into appendix 4.0. The
gap between Telesur and the industry is summarized in table 5.4. The analysis is conducted from -
and limited to - a supply chain point of view.
(b) Analyze data and performance gaps
Supply Chain Cost
These available parameters (table 5.4) show a slight deviation in supply chain cost for about 2 %
from the industry’s average. If Telesur’s objective were to improve its current performance level to
the parity level, a cost reduction of 2% will be required. In terms of value this will add up to USD
1,100,000. If the company wants to achieve a competitive advantage in the industry it should close
an 11% gap equal to USD 6 million. The most logical sequence is to achieve parity, advantage and
then superiority. The difference with the requirement gap is at 20%. Sales and administration cost
are also determined at 6 %, resulting in a requirement gap.
Supply Chain Asset Management efficiency
The figures in table 5.4 show that both cash to cycle time and inventory turnover are at advantage
compared to the industry’s average. Telesur needs less time to convert its inventory into working
capital, which is actually a good sign given the industry’s average of 44,7 times for cash to cycle
and 33,8 times for inventory turnover. Asset turns are at a disadvantage of 0,8 % compared to the
industries average, which leads to a requirement gap.
Shareholder metric Profitability
In general Telesur is less profitable compared to the industry’s level of parity which is based on the
calculated net income of 16% compared to the industry average of 23%. Telesur’s Gross Margin is
in fact 6 % less than the industry’s average. To increase its operating income to the industry’s level
of advantage a 7 % increase in Gross Margin is required.

Shareholder metric effectiveness
The last indicator, return on assets proves Telesur to exploit its assets more effectively when
compared to the industry’s level of parity. The return on assets is calculated at 29%. As the product
positioning grid illustrates a company’s competitive advantage is dependent on the supply chains
that deliver the products or services, which demonstrates that improvement in some areas is needed.
To conclude this gap analysis, the table clearly demonstrates some advantages and disadvantages
resulting in the following summary table 5.5, in which the current status of Telesur is presented.
42
Table 5.5 displays the company’s current status, which is a starting point. The table also displays
which metrics need improvement in order to be at parity or at advantage with the industry and
where it needs to remain competitive. In order to achieve parity (P), advantage (A) or become
superior (S), the next step is to assess existing disconnects in the supply chain and were
improvement is needed. After a series of interviews, the following aggregated disconnects were
identified.

Supply chain disconnect analysis
To further analyze what disconnects exist possibly causing these disadvantages, the above described
metrics were investigated through a series of interviews, which resulted in the following
disconnects. These were also supported by observations.
PLAN
(1.0) Poor forecasting methods, systems and demand management systems.
Forecasting methods are generally based on historical figures. Some of the product groups
such as fixed telephony and mobile services are compared monthly, because of competitive
pressures. Evaluation of financial targets usually is an annual event but structural accuracy
control does not exist. On the other hand structural evaluation of forecasted material
requirement and actual usage does not exist. For some product groups monthly reports are
produced for fixed and mobile services. For fixed services for example the reports contain
annotations about shortages of equipment for customer connections. However, a detailed and
43
consistent description about the amount and type of material, the time and source of
disruption, which causes scarcity, does not exist. This disconnects cause poor asset
management and affect inventory.
(2.0) No supply chain management function. As appendix 5.0 shows all functions are being managed
by their own divisions and are widespread across the organization, but not as interlinked
processes. For example the commercial secretariat and inventory management department
manage prepaid calling card inventory. Disconnect 2 increases supply chain disruption risk for
increased stock and inventory planning and also inefficiency, because of excess tasks.
(3.0) Inadequate performance measurement systems. Telesur’s operational objectives in general are
known but they lack proper execution. Proper performance indicators are not incorporated in
the job tasks. Proper execution of operational objectives remains the bottleneck. Disconnect 3
affects the total supply chain, because adequate performance measurement systems do not
exist.
(4.0) Insufficient coordination of inventory management. Supply of material gets disrupted, as other
departments relocate stock to special projects. An example is the shortage of joint muffs: The
main problem here is that there is no forecasting for execution of special projects, which leads
to hedging and pooling of material needed to support customer connections. The impact is
made visible in the net earnings of the company, caused by relatively high cost of goods sold
and the customer facing metric supply chain flexibility.
SOURCE
(5.0) Supply management and its strategic role remain unclear. Cost reduction objectives based on
purchasing policies have not been singled out. An estimated 14 departments carry out
sourcing, without collaboration with others to reap economies of scale in relevant sourcing
families. Furthermore the supply disruption which leads to inefficiency risk remains as
departments have the discretion to take their own purchasing decisions. These cause
unforeseen purchasing cost and inefficiency.
(6.0) Insufficient utilization of the ERP system Exact Globe. Although information system
integration initiatives have begun within the company, modules containing supply chain
functionalities have not been implemented.
(7.0) Unclear performance management systems; performance management systems are not
integrated in daily activities. For example, for suppliers no key performance indicators have
been defined. However, there are some service level agreements which have been agreed upon
for end customer connections. This disconnect affects all process elements.
44
MAKE
(8.0) The strategic role of inventory management. Proper warehouse systems exist, however they are
not fully integrated. The function of inventory is restricted to storage of stock. Management
information systems regarding stock are not fully utilized to manage stock.
(9.0) Integration of warehousing systems. Differences occur between physical stock and stock
information from the management information systems. This affects the number of days in
which cash is tied up as capital, because on time data available for promotional activities does
not exist.
DELIVER
(10.0) Supplier performance metrics. Supplier delivery Key Performance Indicators (KPI) on level
two are not available, not for the sales branch offices nor for the external resellers. Customer
facing metrics are ill defined, also given the fact that processes related to end customers,
mentioned in 5.3 have to be defined at level 2. Clearly defined distribution strategies do not
exist.
As section 5.3 pointed out the maturity level of supply processes is low, causing the above
described symptoms. Section 5.3 also indicates that an estimated 17% of processes have not been
clearly defined at level 2. In table 5.6 the disconnect summary is presented. Theory has been used to
assess the problem at hand. For guidelines to potential solutions a benchmark comparison will be
conducted. T Mobile was approached as benchmark partner to determine the possible solutions
related to the identified disconnects.

Section 5.5. Potential for Profitable Growth
In the previous section some of the research results have been presented. One of the main findings
includes 5 disconnect areas. The objective of this section is to illustrate what solutions T Mobile
provides to improve the summarized disconnects within Telesur. It is to be stated by the author that
best practises are also a source of solutions besides theory. The same benchmark staircase of
chapter 2 (figure 2.4) will be considered. To avoid repetition of information presented in the
previous section, only the relevant benchmark steps will be compared.
First a description will follow as to which product group will be benchmarked and why the
benchmark partner was chosen. The same SCOR card comparison will follow and what the
benchmarks itself produced as solution to remove disconnects.
Section 5.5.1. Determine What to Benchmark
Using the general benchmark staircase the author will describe why the product group Mobile
Service was chosen for the benchmark;
1. Competitive position; recently the telecommunications market was liberalized allowing two
new telecom operators to compete on the mobile market.
2. Revenue generating share; mobile services contribution is an estimated 38% of the total
companies revenues.
3. Pro-sumption; liberalization resulted in increased buyer power. Telesur must therefore improve
time to market in order to meet customer demand.
Section 5.5.2 Determine Benchmark Partners
T Mobile is the benchmark partner and was chosen because of the companies leading role in the
telecommunications industry in Europe, the availability of company data and the fact that the
company is partly private owned. The company is currently the number 3 leading operator in the
Netherlands based on market share. To put the benchmark comparison into perspective a brief
company comparison is presented. The figures are summarized in table 5.7 Company Comparison.
46
For strategic reasons and availability of figures, separate financial figures for mobile services will
not be included in the comparison.
Table 5.7 Company Comparison

The total amount of subscribers of T Mobile in the Netherlands amounts up to 4,3 million, of which
an estimated 2 million are active subscribers (annual report T Mobile, 2006). In Suriname there are
an estimated 350.000 subscribers. The revenue per employee clearly shows a higher productivity
factor. Information about T Mobile’s supply chain is included in appendix 6.0.
Section 5.5.3 Supply Chain Maturity Model Benchmark
To compare both supply chain processes between Telesur and T mobile, the Supply Chain Maturity
Model was applied. This result is needed to determine the level of supply chain process maturity
within T Mobile and to assess whether a higher level of maturity leads to improved business
operations. The results which were provided by the supply chain department of T Mobile are as
follows.
The result proved that T Mobile’s processes were much more developed than Telesur’s. The lower
levels of maturity for T Mobile are positioned between integrated and linked, while the levels of
Telesur’s supply chain maturity processes are valued between Ad Hoc and Defined. Comparing
Telesur’s supply chain process with T Mobile’s, some contradictions were discovered. The process
elements SOURCE and MAKE at T Mobile were highly developed, against the poorly developed
SOURCE and MAKE processes of Telesur. The highest values within Telesur were given to process
elements PLAN, MAKE and DELIVER, while the same process elements at T Mobile’s showed
relatively lower level of process maturity.
47

The results show that requirements for company performance are based on, but not limited to a firm
supply management functions and MAKE, the production part of the company.
Section 5.5.4 Take Actions to Improve
The purpose of this section is to identify solutions within T Mobile’s business processes for
disconnects shown in table 5.7. Disconnects 1.0, 2.0, 3.0, 4.0 and 5.0 are described by giving
examples of real cases which reflect the situation on hand. Since some disconnects are similar to
each other they were described as one.
DISCONNECT 1.0 &2.0
1) Supply management Telesur is dependent on suppliers because of the remoteness of operations.
Purchasing prepaid calling cards is an example. Instead of exploiting supplier relationships
through the development of long term contracts, calling cards are purchased with an average
frequency of 4 times a year. The current purchasing manner increases supply risk.
2) Performance measurement systems are insufficient for example no supplier metrics have been
determined and the number of availability for prepaid calling cards, handsets and sim cards have
not been set. The questionnaire in appendix 10.0 contains survey results that prove that
measurement systems are not sufficient.
48
BENCHMARK COMPARISON T MOBILE against DISCONNECT 1.0& 2.0 Performance measurement systems are for example customer and internal facing such as
availability, forecast accuracy, variation. Operational objectives of the supply chain department are
measured by the key performance indicators
o velocity, which are average sales of the previous 3 weeks
o availability, the percentage of lost sales,
o yield and depreciation versus stock on hand, which is 1 % of purchased stock.
DISCONNECT 3.0& 4.0
3) Forecasting and Demand management is the bridge between front office and back office.
However the existing level of forecasting within Telesur is low. Demand management is not
part of daily activities. Disconnect 3.0 has been identified when the author approached the
responsible staff member for prepaid calling cards and also for handsets and sim cards.
4) Inventory management functions are traditional and decentralized. This means fragmentation of
inventory management for handsets, sim cards and prepaid calling cards. The inventory
management function is reactive, which means that forecasting and proactive signaling of
supply chain disruption is not part of daily activities.
The responsible staff members for selling, purchasing and inventory management of prepaid calling
cards presented a relevant case. They are employed by the commercial secretariat which supports
the commercial division of Telesur. The staff members are responsible for:
� Distribution to resellers,
� Inventory management of prepaid calling cards
� Purchasing of prepaid calling cards in collaboration with the purchasing department.
The following example describes the abovementioned disconnect in dept;
Appendix 7.0. includes two samples from the commercial department responsible for inventory
management of USD 5 and USD 10. They state that the current forecasting method is based on a 3
month safety stock level. The 3 month safety stock is based on the throughput time of the entire
workflow, which adds up to 3 months (appendix 7.0.). On average 8% of annual amount is sold for
5 USD and 10 USD prepaid calling cards every month.
49
A comparison between the actual order quantities and the 3 month forecasting method proves that
there is no clear pattern which is illustrated in appendix 7.0, and increases the risk of stock
shortages or as excess stock. In percentages, the average stock level should be at 8 %, while the
order quantity should be at three months average equal to 24% (3 months multiplied by 8%). The
results shown in appendix 7.0 prove that the order frequency and purchased amount do not comply
with the methods used, resulting in a deviation about the mean (appendix 7.0) for USD 5 calling
cards and USD 10 calling cards.
The same methodology resulted in the visibility and confirmation of the described disconnect. The
difference between the annual sales and purchased quantities for USD 5 calling cards is determined
at 11% and for USD 10 cards at 26 % (table 5.8). Given the 3 month minimum stock level, 1740204
should be equivalent to the 24 % - i.e. a safety stock of three months for both USD 5 and USD 10
prepaid calling cards. This means that a stock shortage exists of 13 % for prepaid USD 5 calling
cards (11 % excess stock deducted from 24 %). For USD 10 prepaid calling cards this represents
excess stock of 2 % (26 % excess stock deducted from 24 % average stock level).
The figures in table 5.8 have been adjusted because of strategic reasons. To give a better illustration
of excess stock in table 5.8, only the purchased and sold prepaid calling cards are illustrated, the
surpluses or deficit of preceding years have been left out.
Table 5.8 Data Summary
Month Sales Received Annual Difference In %

USD 10 1080837 1363091 282254 26% Source: Inventory management 2007
Another example includes the availability and forecast accuracy percentage of prepaid calling and
handsets (table 5.9.). The availability is measured by dividing the available stock by the velocity of
for example a handset or prepaid calling cards (availability = available stock / velocity). In the table
the velocity of the handset is determined at 12 handsets a week, which is 612 (12 handsets
multiplied by 51 weeks). The available stock is determined at 1142 handsets for a period of eleven
months. The availability percentage is 187%. The same methodology applies for prepaid calling
cards. The figures have been adjusted reasons of confidentiality.

BENCHMARK COMPARISON T MOBILE against DISCONNECT 3.0 and 4.0
At T Mobile accuracy evaluation and control is a method used to compare forecast of two different
periods. Using SAP APO, a software planning tool, the company minimizes supply chain
disruptions and excess inventory. In the next section a brief description will be given for the
presumed cost savings in case Telesur would apply the same key performance indicators of T
Mobile.
DISCONNECT 5.0 Integration of information management systems and centralization of supply chain functions
remains a deficiency, which leads to increased inefficiency. Several departments are responsible for
the supply chain of mobile services. The latter will be exemplified by describing the responsible
function for handsets, calling cards and sim cards;
Handsets
� PLAN; planning of handset is a collaborative effort between the product manager of mobile
services and sales manager mobile services.
� SOURCE; sourcing is also an effort between the product manager mobile services and the
purchasing department.
� MAKE and DELIVER; the inventory department is responsible for the distribution and material
handling of handsets.
Sim cards
� PLAN; the mobile services sales department is responsible for planning inventory and
availability of the sim cards.
� SOURCE; purchasing sim cards is done by the mobile service department in collaboration with
the purchasing department.
� MAKE and DELIVER; the inventory management department is responsible for preparing sim
cards for distribution.
51
Prepaid mobile calling cards
� PLAN; the secretariat of the commercial division is responsible for inventory planning and the
availability of calling cards.
� SOURCE; the secretariat of the commercial division is responsible for purchasing calling cards in
collaboration with the purchasing department.
� MAKE and DELIVER; inventory management is responsible for preparing prepaid calling cards
for distribution.
The abovementioned case description exemplifies the supply chain as being managed as a loose
entity. The process elements for mobile services are being managed by a secretariat from the
commercial division, mobile services from the commercial division, product manager from the
general affairs, purchasing from the operations division and inventory management from operations
division. Although actual disruptions have been limited, the risk of supply chain disruptions still
exists.
BENCHMARK COMPARISON T MOBILE against DISCONNECT 5.0
Compared to T Mobile the supply chain activities are centralized within one supply chain function,
which is part of the channel management department. The supply chain department manages
forecasting, inventory planning of handsets, sims and vouchers. Specialists are assigned to specific
tasks (appendix 6.0.).
Section 5.6 Summary
In chapter five two of the central questions were answered namely “What are the main
characteristics of the existing supply chain?” and “What supply chain disconnects exist within the
existing supply chain”. First the Product Positioning Grid assisted in determining the supply chain
strategy based on the characteristics of the existing product groups. This analysis was followed by
application of the Supply Chain Maturity Model. Application of this model resulted in the
identification of un (der) developed supply chain processes. To determine how these un (der)
developed supply chain processes related to supply chain performance the SCOR model was
applied to compare Telesur’s performance against that of the telecommunications industry. The
results revealed that Telesur performed worse than the industry and that improvement is needed.
52
Further analysis resulted in five major areas of disconnects that affected Telesur’s performance. To
exemplify these disconnects a separate section paid attention to a benchmark between Telesur and T
Mobile. This section provided some insight into available solutions to existing disconnects.
53
CHAPTER 6 CONCLUSIONS AND RECOMMENDATIONS
Section 6.1. Conclusions
The topics related to chapter 6 are summarized in figure 6.0.
FIGURE 6.0. Topics Related to chapter 6
The supply chain of Telesur has never been made visible or analyzed before as interlinked
processes. Neither has a supply chain strategy ever been developed for Telesur in order to maintain
or develop a competitive advantage. In order to develop such supply chain strategy, four central
questions have been asked.
The first one is “What are the appropriate instruments for supply chain analysis? The answer to
this question led to a literature study and resulted in a framework containing three models. The first
one is the product-positioning grid, which assists in understanding the nature of demand and
compares a company’s product against other products in the industry. The model is used to
determine the appropriate supply chain strategy. The second model, which is the supply chain
maturity model, assesses the maturity stage of the supply chain processes. The model is an
instrument used to investigate the relationship between supply chain process maturity and overall
supply chain performance. The third model is the SCOR model which determines supply chain
disconnects that lead to gaps between the benchmarked company and the industry it operates in.
54
The gap is then translated into improvements of the supply chains and what the strategy drivers are,
that connect the strategy with operational objectives.
To answer the second central question “What are the main characteristics of the existing supply
chain?” the models were validated within Telesur;
� Application of the product-positioning grid revealed that all three described product groups
were classified as functional. The results showed that the product groups required an efficient
supply chain strategy. Efficient strategies are characterized by cost reductions and elimination
of non value adding activities. It is to be concluded that one of the themes of the Telesur’s
strategy namely cost reduction, does comply with the conclusions obtained from this research.
� The maturity model was validated to better understand the maturity of supply chain processes
PLAN, SOURCE, MAKE and DELIVER. The result proved that the supply chain processes were
under developed, and that Telesur is not (yet) a process driven organization. The current levels
of maturity are positioned at the level ‘Defined’ (level 1). Especially process element SOURCE
was less developed compared to process elements PLAN, MAKE and DELIVER. The low levels of
maturity cause symptoms leading to inefficiency and unnecessary expenditures.
� The third model SCOR, was applied to further research what the main disconnects were. It
helped answer the following question “What are the supply chain disconnects of Telesur
relative to the best practices in the telecommunications industry? The SCOR card proved that
Telesur needed improvement in specific areas. Disconnects were made visible and five major
areas were revealed: (i) Sourcing, (ii) demand management and forecasting, (iii) information
systems integration, (iv) centralization of supply chain functions, and (v) performance
management. These problematic areas were summarized after a series of interviews. To find
solutions to the existing disconnect Mobile Services of Telesur were benchmarked against T
Mobile. The benchmark resulted in centralization of supply chain functions, integration of
management information systems and performance management, eliminating all forecasting and
demand management errors.
Section 6.2. Recommendations
To answer the problem statement “What supply chain strategy can be applied based on the results
of the supply chain analysis?” a supply chain strategy will be proposed. The aforementioned facts
will be considered along with the constraints presented by Kraljic and Jayashankar which are:
55
1) Government ownership; by law Telesur is not obliged to generate profit, which is not an
appropriate objective in a liberalized market environment with a high level of competition.
2) Economies of scale; the economies of scale lead to supplier dependency which weakens the
negotiation position of Telesur.
Considering the abovementioned, the supply chain strategy should remain one that is efficient. To
ensure successful achievement of strategic objectives which include implementation of the efficient
supply chain strategy, strategic actions are required. First the process elements SOURCE, MAKE
and DELIVER need to be developed towards the process maturity level of process element PLAN.
The process element PLAN is relatively mature compared to the process elements SOURCE,
MAKE and DELIVER. Before process development takes place the process elements need to be
clearly defined and made visible as interlinked processes given the current level of process
maturity. Last, removal of identified disconnects will impact development of supply chain
processes SOURCE, MAKE and DELIVER. On the long run Telesur should try to grow towards
the highest level of supply chain maturity.
Further development of supply chain process elements is dependant on the level of implementation
difficulty and the impact on Telesur’s performance. To decide on a supply chain process element
that impacts Telesur’s performance the most and one which has a high degree of difficulty, further
research is necessary. This future study will not only have to reveal what impact these supply chain
process element have on Telesur’s performance, but also what risks exists when certain supply
chain process elements are not properly developed. Further research must also include an in dept
analysis on the competitive position of Telesur within the Region.
