even wait despite USA made cars were available.

parts were within the tolerance limit but Japanese made parts
were more or less identical.
• Suppose a part has to be 1 foot long with plus/minus 1/8 “ as
tolerance japanese parts were within 1/16 “ tolerance.
10. Japan and Quality
• Role of E. Edwards Deming- statistical quality control methods
• Culture -A strong organizational culture is characterized by
“intense emotional attachment and the internalization of
„clearly enunciated company values‟ that often replace formal
structures”- kunda gideon
• work environment-Life time Employment , unionism, seniority
wages
11. Role of Edwards Deming
• Deming is the final, and arguably most important, variable in the
equation that led to Japan‟s economic revolution after the Second
World War.
• As Deming himself said, “Quick returns, whether by acquisition, or
by divestiture, or by paper profits or by creative accounting, are
self-defeating” (Deming 1985). When Japan adopted Deming‟s
techniques, Japanese firms were not thinking about profit margins or
stock prices. For them, it was about the success of Japanese
industry, and the future of Japan as a nation.
12. Worker Involvement
• Total quality management, quality control circles, quality
control groups, etc. all accomplish the same goal by making the
workers invested both physically and mentally in the
manufacturing process.
• Incentives are given to workers to provide suggestions as to how
manufacturing can be made more efficient
• There is an intense degree of cooperation between workers, and
even departments, within a firm
