Doctor Shingeo Shingo

Dr. Shigeo Shingo

Dr. Shingo, born in Saga City, Japan, was a Japanese industrial engineer who was considered as the world's leading expert on manufacturing practices and the Toyota Production System. Few individuals have contributed as much to the development of the ideas called TQM, JIT, and Lean as did Shigeo Shingo. Over the course of his life, Dr. Shingo wrote and published 17 books, eight of which were translated from Japanese into English. Many years before they became popular in the Western world, Dr. Shingo wrote about the ideas of ensuring quality at the source, flowing value to customers, working with zero inventories, rapidly setting up machines through the system of "single-minutes exchange of die"(SMED)*, and going to the actual workplace to grasp the true situation there ("going to gemba"). He worked extensively with Toyota executives, especially Mr. Taiichi Ohno, who helped him to apply his understanding of these concepts in the real world.

The Shingo Model booklet is free to download
and will teach you the basic concepts.
