Quality Gurus: 

Quality Gurus W Edwards Deming Joseph Juran Philip Crosby Shigeo Shingo Kaoru Ishikawa Yoshio Kondo Taiichi Ohno

W Edwards Deming (1900-1993)the key to quality: reducing variation: 

W Edwards Deming (1900-1993) the key to quality: reducing variation Electrical Engineering, University of Wyoming, 1921 PhD, Yale University Western Electric Hawthorne, Chicago US census statistician, 1939/40 Teaching Shewhart methods, 1942 invited to Japan after the war .... Quality, Productivity and Competitive Position, 1982 Out of the Crisis, 1986/88 British Deming Association, Salisbury

W Edwards Deming: 

W Edwards Deming regarded by the Japanese as the chief architect of their industrial success “all processes are vulnerable to loss of quality through variation: if levels of variation are managed, they can be decreased and quality raised” quality is about people, not products

W Edwards Deming: 

W Edwards Deming Core element is the “management circle” planning do/implementation check/study action PDCA (or PISA) cycle Continuous improvement (Kaizen) teamwork and competence in problem solving

W Edwards Deming: 

W Edwards Deming “Out of the Crisis” is “required reading for every chief executive in British industry who is serious about ensuring the international competitiveness of his company” Sir John Egan (Jaguar Cars) in Director magazine, September 1988

W Edwards Deming: 

W Edwards Deming Out of the Crisis (1984) having a satisfied customer is not enough profit in business comes from repeat customers customers that boast about your product and service customers that bring friends with them necessary to anticipate customer needs

Joseph Juran (b.1904)company wide quality cannot be delegated: 

Joseph Juran (b.1904) company wide quality cannot be delegated Western Electric manufacturing, 1920s AT&T manufacturing Quality Control Handbook, 1951 Management of Quality courses Juran on Planning for Quality, 1988

Joseph Juran: 

Joseph Juran structure CWQM concept: Company-Wide Quality Management essential for senior managers to involve themselves define the goals assign responsibilities measure progress

Joseph Juran: 

Joseph Juran empowerment of the workforce quality linked to human relations and teamwork key elements identifying customers and their needs creating measurements of quality planning processes to meet quality goals continuous improvements

Philip Crosby (1926-2001)conformance to requirements: 

Philip Crosby (1926-2001) conformance to requirements Martin missiles QM at ITT, then corporate VP 1979: Quality is Free Philip Crosby Associates Inc. 1984: Quality without Tears “Do It Right First Time” “Zero Defects”

Philip CrosbyFour absolutes of quality management: 

Philip Crosby Four absolutes of quality management quality is defined as conformance to requirements, not as goodness or elegance the system for creating quality is prevention, not appraisal the performance standard must be Zero defects, not that’s close enough the measurement of quality is the Price of Nonconformance, not indices

Philip Crosby: 

Philip Crosby 1992: “Quality, meaning getting everyone to do what they have agreed to do and to do it right first time is the skeletal structure of an organisation, finance is the nourishment and relationships are the soul”

Philip Crosby: 

Philip Crosby manufacturing companies spend around 20% of revenue doing things wrong, then doing them over again service companies may spend 35% of operating expenses in a similar way

Four Absolutes of Quality Management (Crosby, 1979): 

Four Absolutes of Quality Management (Crosby, 1979) Cost of Quality classified as: Prevention costs Appraisal costs Failure costs

Cost of Quality: prevention costs: 

Cost of Quality: prevention costs design reviews product qualification drawing checking engineering quality orientation supplier evaluations supplier quality seminars specification review process capability studies tool control operation training quality orientation acceptance planning zero defects programme Quality Audits preventative maintenance

Cost of Quality: appraisal costs: 

Cost of Quality: appraisal costs prototype inspection and test production specification conformance analysis supplier surveillance receiving inspection and test product acceptance process control acceptance packaging inspection status measurement and reporting

Cost of Quality: failure costs: 

Cost of Quality: failure costs consumer affairs redesign engineering change order purchasing change order corrective action costs rework scrap warranty service after service product liability

Shigeo Shingo (b.1909-1990)Poka-Yoke: mistake-proofing: 

Shigeo Shingo (b.1909-1990) Poka-Yoke: mistake-proofing 1930: ME degree from Yamanashi Tech Taipei Railway Factory, Taiwan consultant with Japan Management Assn 1955: training at Toyota Motor Company 1959: Institute of Management Improvement 1961-64: concept of Poka-Yoke

Shigeo Shingo: 

Shigeo Shingo Poka-Yoke: mistake-proofing identify errors before they become defects stop the process whenever a defect occurs, define the source and prevent recurrence 1967: source inspection + improved PY prevented the worker from making errors so that defects could not occur Zero Quality Control

Kaoru Ishikawa (1915-1989)Pareto and cause-and-effect diagrams: 

Kaoru Ishikawa (1915-1989) Pareto and cause-and-effect diagrams 1939: engg. graduate of Tokyo Univ 1947: Assistant Professor 1955-60: Company-wide QC movement 1960: Professor (still at Tokyo!)

Kaoru Ishikawa: 

Kaoru Ishikawa “quality does not only mean the quality of the product, but also of after sales service, quality of management, the company itself and human life”

Kaoru Ishikawa (points 1-7 of 15): 

Kaoru Ishikawa (points 1-7 of 15) product quality is improved and becomes uniform. Defects are reduced reliability of goods is improved cost is reduced quantity of production is increased, rational production schedules are possible wasteful work and rework are reduced technique is established and improved inspection and testing costs are reduced

Kaoru Ishikawa (points 8-15 of 15): 

Kaoru Ishikawa (points 8-15 of 15) rational contracts between vendor/vendee sales market is enlarged better relationships between departments false data and reports are reduced freer, more democratic discussions smoother operation of meetings more rational repairs and installation improved human relations

Yoshio Kondo (b.1924)motivation of employees is important: 

Yoshio Kondo (b.1924) motivation of employees is important 1945: graduated from Kyoto University 1961: doctorate in engineering & Prof 1987 Emeritus Professor 1989: Human Motivation - a key factor for management 1993: Companywide Quality Control leadership is central to implementation of TQM
