ABSTRACT

The classic seven quality tools were originally published as articles in the late 1960s in the Japanese quality circle magazine Quality Control for the Foreman. Around that time, most Japanese books on quality were too complicated for factory foremen and production workers, so Kaoru Ishikawa used the articles from Quality Control for the Foreman as a basis for the original 1968 version of Guide to Quality Control. The book was frequently used as a textbook for tools in quality (Ishikawa, 1991).
