Introduction: What is Quality?
– Merriam Webster’s Collegiate Dictionary, 10th Edition(1994) defines quality as
“an inherent feature; degree of excellence; and superiority in kind
Some definitions that have gained wide acceptance in the corporate world
“Meeting or exceeding customer expectations”
Juran, one of the quality gurus, defined quality as;
Fitness for Use

Introduction
Based on Juran‘s definiton, quality therefore does not only have to be perceived by the customer, but the customer experience of quality of a product or service is more important.
Quality does not mean an expensive product

Introduction
The American National Standards Institute (ANSI) and the American Society for Quality (ASO) defined quality as;
The totality of features and characteristics of a product or service that bears on its ability to satisfy customer’s stated and implied needs.

Introduction
What is a customer?
Anyone who is impacted by the product or services delivered by an organization
External customer- the end user
Internal customer- other divisions of the company that receive the processed product.
Page 9
Introduction
What is a product?
the output of a process carried by the organization. It may be goods (e.g. cellphones), software(e.g. a computer code, a report) or service (e.g. banking, insurance
Page 10
Introduction
How is customer satisfaction achieved?
Two Dimensions of Quality:
Product feature- refers to the quality of design.
In a manufacturing industry, it includes performance, reliability, durability, ease of use, esthetics, etc
In a service industry, customer satisfation is gained through accuracy, timeliness, friendliness and courtesy, knowledge of server, etc.
Page 11
Introduction
Freedom from deficiencies – refers to quality of conformance
Conformance to standards- ability of the product or service to conform to the stated and implied requirements of customers.
Higher conformance means fewer complaint and increased customer satisfaction
Page 12
Introduction
Why Quality?
Reasons why quality is a cardinal priority for most organizations.
Competition
Changing customer-the new customer is not only commanding priority based on volume but is more demanding about the “quality system”
Changing product mix – the shift from low volume high price to high volume, low price resulted in a need to reduce the internal cost of poor quality.
Page 13
Introduction
Product complexity- as systems have become more complex the reliability requirments for suppliers of components have bome more tough
Higher level of customer satisfaction- higher customer expectations are getting spawned by increasing competition.

History of quality management
…To know the future, know the past!
Before Industrial Revolution, skilled craftsmen served both as manufacturers and inspectors, building quality into their products through their considerable pride in their workmanship.
Industrial Revolution changed this basic concept to interchangeable parts. Likes of ;
– F. W. Taylor (“scientific management” fame) emphasized on the use of scientific standards equitably to managers as well as workers.

History of quality management
…To know the future, know the past!
– Adam Smith who advocated dividing the labor required to make a product into simple, repetitive tasks in order to develop workers’ skills, save time and use specialized tools
– Frank and Lilian Gilbreth’s Time and Motion economy, they believed that a way a task is performed is as important as the time it takes to do it.

History of quality management
Statistical approaches to quality control started at Western Electric with the separation of inspection division. Pioneers like Dr. Walter Shewhart, Deming W.Edwards and Joseph M. Juran were all employees of Western Electric.
– Dr. Walter Shewart (1891-1967) developed the Plan, Do, Check Act (PDCA) cycle for continuous improvement which is in use even today
After World War II, under General MacArthur's Japan rebuilding plan, Deming and Juran went to Japan.
- Deming W, Edwards (1900-1993) modified PDCA cycle of Shewart to the Plan, Do, Study and Act (PDSA). He also advocated the extensive used of statistical quality control theory to Japanese industry along with Juran.

History of quality management
Deming stressed the importance of suppliers and customers for the business development and improvement.
– He believed that people do their best and it is the system that must change to improve quality.
– His 14 Points for Management formed the basis for his advise to top Japanese management.
Page 18
History of quality management
Joseph M. Juran (1904), developed the Statistical Quality Handbook for Western Electric Company. He identified Fitness of quality and popularized the same
Juran travelled to Japan to teach his own theories- that hands-on management was necessary at all levels of corporation to ensure quality control and that problems are opportunities to make improvements.
– His approach is still known today as the Juran Trilogy; quality planning, quality control and quality improvement

History of quality management
In Japan the following individual took seed from this training and went on to developed their own major contributions to what is now Total Quality Management:
Kaoru Ishikawa (1915-1989), strongly advocated the use of cause and effect diagram to provide a true representation of the organizational impact and procedures. He developed Fishbone or Ishikawa diagram for cause and effect analyis.
Taichi Ohno, known as the father of just-inTime production. He is also the co-creator of Toyota Production System (TPS)
Page 20
History of quality management
Shigeo Shingo worked with Ohno on the TPS process and developed some of its popular concepts including poka-yoke (which means “mistake-proof in Japanese and refers to taking human judgement out of some types of production, thereby minimizing human errors)

History of quality management
Next 20 odd years, when top managers in USA focused on marketing, production quantity and financial performance, Japanese managers improved quality at an unprecedented rate.
Market started preferring Japanese products and American companies suffered immensely.
America woke up to the quality revolution in early 1980s. Ford Motor Company consulted Dr. Deming to help transform its operations.
(By then, 80-year-old Deming was virtually unknown in USA. Whereas Japanese government had instituted The Deming Prize for Quality in 1950.)

History of quality management
Managers started to realize that “quality of management” is more important than “management of quality.” Birth of the term Total Quality Management (TQM).
– TQM – Integration of quality principles into organization’s management systems.
Early 1990s: Quality management principles started finding their way in service industry. FedEx, The Ritz-Carton Hotel Company were the quality leaders.
TQM recognized worldwide: Countries like Korea, India, Spain and Brazil are mounting efforts to increase quality awareness.

1. Balance Scorecard – Robert Kaplan and David Norton, suggest that a business’s executive team measure progress in four areas that are equally important
• knowledge
• financial performance
• Internal business process and
• Learning/growth
Using the knowledge to focus the entire organization and its
various programs on “balancing” the scorecard

2. ISO Standards - The International Standardization Organization (ISO).
- headquartered in Switzerland
- more than 100 nations are “members”, that define and agree on, and abide by a wide rang of product and process safety and quality standards
- the idea behind ISO certification is that products made in different nations be compatible for use in others.
- this allows manufacturers to buy parts from suppliers in other countries.

- The Quality Management Systems (QMS) standards are know as “ISO 9000” family of standards; (ISO 9000-2000, ISO 9001-2000, ISO 9004-2000); the environmental management system are ISO 14000 and so on.
3. Just-in-Time – a manufacturing theory of producing just enough product to fill current orders as they are due. “just –in time for them to be used”

4. Kaizen – a Japanese term fro “unending improvement”
-Kaizen represents a system in which management encourages and implements small, incremental improvements, involving employees as team members and creating a culture of workers who all striving to do better
- it focuses on simplifying complex process and training employees to measurable improve them.

5. Quality Circles – based on a Japanese method of grouping people together in “Quality Control” (QC), meetings where they shared their expertise and worked to solved a problem or improve process.
6. Six Sigma – created by Motorola in 1980s. The name refers to a scientific way of describing quality based on variations that occur in any process-plus or minus three “sigmas.” Sigma is the Greek letter that signifies the standard deviations in a mathematical formula.
-the “sigma level” quantifies defects per million opportunities (DPMO)

7. TOTAL QUALITY MANAGEMENT – a comprehensive, organization-wide effort to improve the quality of products and services, applicable to all organizations.
- TQM quality is managed by the total effort of an organization, and that each department or phase of production is responsible for making its part of the product or services as flawless as possible before passing it on the next user or phase.
