Dr. Genichi Taguchi :
Dr. Genichi Taguchi was an engineer and statistician born in 1924 in Tokamachi town of Japan.
In 1950, he joined the Electrical Communications Laboratory of the Nippon Telegraph and Telephone Corporation just as statistical quality control was beginning to become popular in Japan under the influence of W. Edwards Deming and the Japanese Union of Scientists and Engineers. Taguchi spent his twelve years in developing methods for enhancing quality and reliability. Even at this point, he was beginning to be consulted widely in Japanese industry, with Toyota being an early adopter of his ideas.
