◎提唱者（Walter A. Shewhart）
Bell Telephone’s engineers had been working to improve the reliability of their transmission systems. Because amplifiers and other equipment had to be buried underground, there was a business need to reduce the frequency of failures and repairs. When Dr. Shewhart joined the Western Electric Company Inspection Engineering Department at Hawthorne in 1918, industrial quality was limited to inspecting finished products and removing defective items. （http://en.wikipedia.org/wiki/Walter_A._Shewhart）
◎William Edwards Deming (October 14, 1900 - December 20, 1993)
[He] was an American statistician, college professor, author, lecturer, and consultant. Deming is widely credited with improving production in the United States during World War II, although he is perhaps best known for his work in Japan. ...After World War II (1947), Deming was involved in early planning for the 1951 Japanese Census. He was asked by the Department of the Army to assist in this census. While he was there, his expertise in quality control techniques, combined with his involvement in Japanese society, led to his receiving an invitation by the Japanese Union of Scientists and Engineers (JUSE). [5]
JUSE members had studied Shewhart's techniques, and as part of Japan's reconstruction efforts they sought an expert to teach statistical control. During June-August 1950, Deming trained hundreds of engineers, managers, and scholars in statistical process control (SPC) and concepts of quality. He also conducted at least one session for top management.[9] Deming's message to Japan's chief executives: improving quality will reduce expenses while increasing productivity and market share.[1] Perhaps the best known of these management lectures was delivered at the Mt. Hakone Conference Center in August of 1950.(http://en.wikipedia.org/wiki/W._Edwards_Deming)
