TOTAL QUALITY MANAGEMENT
Introduction
CHE 460
WHAT IS QUALITY?
Experts Says:
“Fitness for use” (Juran)
“Conformance to purpose” (Crosby)
Degree to which a set of inherent characteristic fulfills requirements(ISO)
“The characteristics of a product or service that bear on its ability to satisfy stated or implied needs” or “ a product or service free of deficiencies “ASQ)
......
CUSTOMER DEFINITION?

CHE 460
DIMENSION OF QUALITY
Design Quality • Characteristics of product or service?
• Target customer segment?
• Material and method will be used?
• ........
Example: “economy” and “business class” in
flight; “cotton” or “silk” shirt.
Conformance quality
• Conformance to design or intended product
characteristics
Example: everything being normal in an
economy class flight, or defect free cotton
shirt.
Design quality may differ for various products
but conformance quality has to be high for all.

QUALITY MANAGEMENT
Quality control (Inspection and testing) • Controlling the product • Finding the defected product and remove • Result oriented
Quality assurance • Controlling the process/system • Preventing the nonconformance to quality • Process oriented
TQM • Targeting quality in all activities
• Managing all aspects (planning, executing and controlling) of quality efforts
• Involving all people, processes and systems

HISTORY OF QUALITY MANAGEMENT
Before 1900 • Production in small shops
• Masters are responsible for quality and everything
• Others help masters

• Division of labor, functional organizations
• “Quality control” department
1930s • Introduction of human side of management
• Introduction of statistical process control, sampling and other techniques into business
• Amount of production is key for success
CHE 460

PRINCIPLES
CHE 460
CUSTOMER FOCUS
Who is the customer?
• People or other organizations that use the product or service of the organization
Customer is the reason to exist.
Success depends on customer behavior toward organization
Customers should be satisfied:
• Determine and meet the need and expectation
• Handle the complaints effectively
• Increase the “perceived quality” by the customer
CHE 460
CUSTOMER FOCUS
Internal customer • Each step is the customer of previous
step
• The firm is a chain of internal customers from supplier to final customer
• The strength of the chain is equal to strength of the weakest ring.
Satisfaction of all stake holders • Share holder
• Employees
• Customer
• Suppliers
• Society
• .....
CHE 460
PEOPLE FIRST: PARTICIPATION
The contribution of everybody is valuable.
The person who does the job also know how to improve.
People tend to do their best if they can (Theory Y).
Hence, achieve the participation of everyone in all activities (decision making, problem solving, improvement...) should be achieved
CHE 460
PEOPLE FIRST : TRAINING
Continuous change New needs and problems Need for new knowledge and skills
Managing competencies
• Competency needs
• Measuring the competencies
• Developing competencies
Quality training
• Increase awareness and commitment
• Train in quality tools and process
“Quality starts and ends with training” Ishikawa
CHE 460
PEOPLE FIRST : EMPOWERMENT
The knowledge and skills of employee should be developed to handle responsibility and authority
Responsibility and authority should be given
Employee should be supported to succeed to use responsibility and authority
Traditional organizational structure Structure based on empowerment (symbolic representation)
CHE 460
TEAMWORK
“Team is a collection of “limited number of members”
to “achieve a common goal” by “working together”.
Example: Football teams, basketball teams,
Orchestras
CHE 460
CHARACTERISTICS OF AN EFFICIENT TEAM
Well defined goals and borders
Acceptance of the team goals by all members and
willingness to achieve
Well balanced and complementary roles and
responsibilities
Complementary expertise

More people are satisfied by the results
Help to improve communication and trust in
workplace.
Help to meet the socialization needs (motivation)
....

CHE 460
LONG TERM FOCUS
Long and short term benefits may be
conflicted, and there is a tendency
“to save the day!”
Success comes in long term focus
and efforts.

CHE 460
PROCESS-SYSTEM FOCUS
Activities Inputs Output
Information, energy, material, effort....
Properties of a process
• Has a purpose, all activities should be to achieve this purpose
• Its elements interact with each other and contribute the result.
• The total output is more valuable than total input.
Process in a company: purchasing, production, hiring, training...
Improving the process improve the results (product, service...)
Applications: process management, process improvement....
“80% of problems come from the system” Deming
Information, energy, material, effort....
CHE 460
CONTINUOUS IMPROVEMENT
Types of development • Revolutionary (radical)
• Evolutionary (small/continuous)
Radical Change • System, technology...
change
• Top management is responsible
Small/continuous • All process and activities,

• Everybody is responsible

PREVENTIVE APPROACH
Preventing the problems is usually better than fixing after occurrence.
• Examples: Vaccine to babies, preventive maintenance of cars
The same is usually true for product and services although it is not obvious.
• To prevent the defected product reaching the customer
• To reduce the cost
It is related to process-system approach (well operating process prevent the problems in the product and service)
This is the principle behind ISO 9000
CHE 460
FACT BASED DECISION-MAKING
For an effective decision
• Collect data about the processes
• Analyze
• Decide/act
Applications
• Quality tools
• Statistics, statistical process
control
• Problem solving process
• Continuous improvement process
• ....
