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.

Complimentary Lean Rapid Plant Assessment (RPA) – The Lean Rapid Plant Assessment (RPA) process is designed to give the global community a fast, simple, and effective method to measure the lean performance of existing manufacturing and service industries against a standard set of expectations.

RPA has been used in over 440 times in more than 230 manufacturing and service industries from automotive suppliers, aerospace companies, medical devices plants, pharmaceutical facilities, book manufacturers, and microbreweries from 1998 to 2019.

Inputs to the assessment process are plant tour observations made during a typical plant visit and factory tour. Time to conduct the tour should be from 30 minutes to a few hours.

Outputs from the assessment process is an overall score, relative to a general manufacturing database.  First impression of a plant’s lean manufacturing capabilities.

The Lean RPA is based primarily upon the "Read a Plant Fast," article by R. Eugene Goodson and originally published in the Harvard Business Review (R0205H) May 2002 issue.
