Three Old Pieces of TQM

Refering the historical contributions of quality gurus, we have to see the implication of their contributions rather than listen their stories. These historical contributions are what Liu Yuan-Zhang, the father of Chinese quality, said: "Three Old Pieces of TQM are the Control Chart, the Sampling Acceptance table, and the Orthogonal Experiments. They all have their own mathematical theory and successful applications, in the 1950s and 1960s; most of quality practitioners could understand their usage. When I came back China from U.S. and Japan in 1955, I just brought with these three pieces." I always put Liu Yuan-Zhang's saying in my mind, because these "Three Old Pieces" are the basic capabilities why I could do something in the early stage of my quality career, so their theoretical basis and practical application should be understood deeply. Solving the quality problems, statistical methods and thinking way is one of the important tools, but also need to integrate the methodolgies of essence of substance, process of business and psychology.
