William Edwards Deming was an American statistician, professor, author, lecturer, and consultant. He promoted the Shewhart Cycle"Plan-Do-Check-Act" named after Dr. Walter A. Shewhart so often, that it has been also called the Deming Cycle, but not by him. He is best known for promoting his management method called 14 Points which is based and derived on a system of thought called the System of Profound Knowledge consisting of four components: the appreciation of a system, understanding of variation, psychology and a theory of knowledge. These components work together and should not be separated
In Japan, from 1950 onward, he taught top business managers how to improve design, product quality, testing, and sales by various means, including the application of statistical methods. Deming made a significant contribution to Japan's later reputation for innovative, high-quality products, and for its economic power. He is regarded as having had more impact upon Japanese manufacturing and business than any other individual not of Japanese heritage. Despite being honored in Japan in 1951 with the establishment of the Deming Prize, he was only just beginning to win widespread recognition in the U.S. at the time of his death in 1993. President Reagan awarded him the National Medal of Technology in 1987. The following year, Deming also received the Distinguished Career in Science award from the National Academy of Sciences.
