both as manufacturers and inspectors, building quality
into their products.

Industrial Revolution changed this basic concept to
interchangeable parts. Likes of Thomas Jefferson and
F. W. Taylor (“scientific management”.

•
Statistical approaches to quality control started at
Western Electric with the separation of inspection
division. Pioneers like Walter Shewhart, George
Edwards, W. Edwards Deming and Joseph M. Juran
were all employees of Western Electric.
•
After World War II, under General MacArthur's Japan
rebuilding plan, Deming and Juran went to Japan.
95
•
Deming and Juran introduced statistical quality control
theory to Japanese industry.
•
The difference between approaches to quality in USA
and Japan: Deming and Juran were able to convince
the top managers the importance of quality.
•
After 20 years Market started preferring Japanese
products and American companies suffered immensely.
96
•
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.)
•
Managers started to realize that “quality of
management” is more important than “management of
quality.” Birth of the term Total Quality Management
(TQM).
