Shigeo Shingo

Updated: Jan 26



"There are four purposes of improvement: easier, better, faster, cheaper. These four goals appear in the order of priority" _Shigeo Shingo

Shigeo Shingo (1909–1990) was a Japanese industrial engineer considered as the world’s leading expert on manufacturing practices and the Toyota Production System (TPS). After having worked as a technician specializing in fusions at the Taiwanese railways in Taipei at the end of the World War II, in 1945, he started to work at the Japan Management Association (JMA) in Tokyo, becoming a consultant focused on the improvement of Factory Management. Gathering tips from the improvement experiences in the field he had in 1950 at Toyo Ind. (now Mazda) and in 1957 at the sites in Hiroshima of the Mitsubishi Heavy Industries, since 1969 Shingō got involved in some actions in Toyota Motor Corporation (Toyota) for the reduction of set-up time (change of dies) of pressing machines which took him to the formulation of a specific technique based on operational analysis, which shortened set-up times from 1 to 2 hours (or even half a day) per each exchange of dies to a rapid setting of a few minutes. The method spread out under the English denomination Single Minute Exchange of Die, abbreviated as SMED.

"The most dangerous waste is the waste we don't recognize" _Shigeo Shingo



Since 1947, Shingo had been involved all over Japan in the training of thousands of people, who joined his courses on the fundamental techniques of analysis and improvement of the operational activities in factories (among which the P-Course, or Production Course).


Shingo may well be known better in the West than in Japan, as a result of his meeting Normen Bodek an American entrepreneur and founder of Productivity Inc. In 1981 Bodek travelled to Japan to learn about the Toyota Production System, coming across books by Shingo, who as an external consultant had been teaching Industrial Engineering courses at Toyota since 1955.

Shingo had written his Study of the Toyota Production System in Japanese and had it translated into English in 1980. Bodek took as many copies of this book as he could to the USA and arranged to translate Shingo's other books into English, eventually having his original study re-translated. Bodek also brought Shingo to lecture in the USA and developed one of the first Western lean manufacturing consultancy practices with Shingo's support.


In 1988, the Jon M. Huntsman School of Business at Utah State University recognized Dr. Shingō for his lifetime accomplishments and created the Shingo Prize for Operational Excellence that recognizes world-class, lean organizations and operational excellence.

"Lean is a way of thinking, not a list of things to do" _Shigeo Shingo

The theorist of important innovations related to Industrial engineering, such as Poka-yoke and the Zero Quality Control, Shingo could influence fields other than manufacturing. For example, his concepts of SMED, mistake-proofing, and "zero quality control" (eliminating the need for inspection of results) have all been applied in the sale process engineering.
