Kaoru Ishikawa was most noted for the development of the Ishikawa, Cause and Effect or Fishbone diagram, however his impact on quality spread much further than just cause and effect. Dr. Ishikawa was also the chief executive director of JUSE and played a key role in the success of quality circles. Along with these accomplished executive positions Dr. Ishikawa was a member of the committee that developed the auditing system for the Deming prize which is still awarded today.
Even today long after Dr. Ishikawa passed away, organizations all over the world study his notable techniques and great examples of quality. Almost every inspector, production employee and engineer has held a fishbone diagram in their hands at one time or another. Dr. Ishikawa is a true pioneer of statistical analysis and quality. From 1915 to 1989 a great era was born which Dr. Ishikawa often referred to as the "thought revolution," but even today the many great principles and philosophical approach of Dr. Ishikawa influences the world. There is little doubt that the great effects of quality in today's times can be traced to a root cause entitled Dr. Ishikawa.
