Kaoru Ishikawa (石川 馨, Ishikawa Kaoru, July 13, 1915 – April 16, 1989) was a Japanese organizational theorist and a professor in the engineering faculty at the University of Tokyo who was noted for his quality management innovations. He is considered a key figure in the development of quality initiatives in Japan, particularly the quality circle.[1] He is best known outside Japan for the Ishikawa or cause and effect diagram (also known as the fishbone diagram), often used in the analysis of industrial processes.

Kaoru Ishikawa was born in Tokyo, the eldest of the eight sons of Ichiro Ishikawa. In 1937, he graduated from the University of Tokyo with an engineering degree in applied chemistry. After college, he worked as a naval technical officer from 1939 to 1941. From 1941 to 1947, Ishikawa worked at the Nissan Liquid Fuel Company. In 1947, Ishikawa started his academic career as an associate professor at the University of Tokyo. He undertook the presidency of the Musashi Institute of Technology in 1978.
In 1949, Ishikawa joined the Japanese Union of Scientists and Engineers (JUSE), an organization developed to promote systematic studies needed to stimulate the nation's economy. After World War II, Japan experienced rapid and sustained economic growth. This was mostly achieved due to the rapid development of their manufacturing and the industrial sectors. At the time before the Japanese Economic Miracle, the United States still perceived Japan, as a producer of cheap wind-up toys and poor-quality cameras. It was with the help of Ishikawa's skill at mobilizing large groups of people towards a specific common goal that was largely responsible for Japan's quality-improvement initiatives. He translated, integrated and expanded the management concepts of W. Edwards Deming and Joseph M. Juran into the Japanese system. Ishikawa used this concept to define how continuous improvement (kaizen) can be applied to processes when all variables are known.[2]
After becoming a full professor in the engineering faculty at the University of Tokyo (1960), Ishikawa introduced the concept of quality circles (1962) in conjunction with JUSE. This concept began as an experiment to see what effect the "leading hand" (Gemba-cho) could have on quality. It was a natural extension of these forms of training to all levels of an organization (the top and middle managers having already been trained). Although many companies were invited to participate, only one company at the time, Nippon Telephone & Telegraph, accepted. Quality circles would soon become very popular and form an important link in a company's Total Quality Management system. Ishikawa would write two books on quality circles (QC Circle Koryo and How to Operate QC Circle Activities).
According to Quality Digest, one of his efforts to promote quality were the Annual Quality Control Conference for Top Management (1963) and several books on quality control (the Guide to Quality Control (1968) contained the first published example of a Pareto chart.[3]) He was the chairman of the editorial board of the monthly Statistical Quality Control. Ishikawa was involved in international standardization activities.
1982 saw the development of the Ishikawa diagram, which is used to determine the root causes of a problem.
After Ishikawa died in 1989, Juran delivered this eulogy:[4]
There is so much to be learned by studying how Dr. Ishikawa managed to accomplish so much during a single lifetime. In my observation, he did so by applying his natural gifts in an exemplary way. He was dedicated to serving society rather than serving himself. His manner was modest, and this elicited the cooperation of others. He followed his own teachings by securing facts and subjecting them to rigorous analysis. He was completely sincere, and as a result was trusted completely.
