Shigeo Shingo

from Wikipedia, the free encyclopedia

Shingō Shigeo ( Japanese 新 郷 重 夫 ; * 1909 ; † 1990 ) was an engineer and one of the leading protagonists of quality management in manufacturing processes in Japan. He is considered a co-developer of the Toyota Production System TPS, developer of the fault source inspection (Engl. Source inspection), as part of the "Toyota Production System" TPS, he developed a prevention concept ( " Poka Yoke "), Rüstzeitreduktionen ( SMED ) and setup concepts (IED and OED ) and was the author of various books.

Professional background

Shigeo Shingo graduated from Yamanashi Technical College in 1930 as a graduate engineer and then worked at the Taipei Railway Factory in Taiwan, where he introduced scientific management. In 1945 he became a member of the Japanese Management Association; This was followed by other activities in various Japanese organizations, such as a manager in the Computing Office, the Fukioko Office, and chairman of the Department of Education. Here he dealt intensively with the principle of statistical quality control for the first time. In 1954, Toyota hired him as a consultant. In 1955 he took over the management of industrial company optimization, where he was involved in the development of the “Toyota Production System” (TPS) by later using both the Poka Yoke principle and the SMED ( Single Minute Exchange of Die ) concept. brought in. For the next three years (1956–1958) he also worked on minimizing production time in shipyard construction. Eventually he succeeded in shortening the manufacturing time by 50%, after which the process he developed was adopted in large parts of Japan. In 1959 Shigeo founded the "Institute of Management Improvement", which he himself presided over.

From 1961 to 1964 Shigeo Shingo developed the so-called Poka-Yoke principle, which is an error control technique to avoid errors in order to prevent a lack of customer satisfaction and the possible high costs for error elimination. Later, in collaboration with Toyota, he also designed the SMED (Single Minute Exchange of Die) process, which was intended to minimize losses due to the changeover time between individual production steps. From 1971 Shingo was also active on an international level, so he led practical training courses at several European and US companies.

In 1988 the Shingo Prize for Excellence in Manufacturing was established and is considered one of the highest awards in the field of quality management.

Shingo received honorary doctorates from Utah State University and the Université de Toulouse.

Poka-yoke

The aim of the poka-yoke principle (Japanese: poka: error, yoke: avoidance) is to avoid errors at an early stage that could lead to high costs or loss of quality in the further course of production. Correspondingly, measures are taken to prevent such errors from occurring at the interfaces between the work system and humans, for example. Poka-Yoke is therefore a form of preventive quality technology. It has the parts source of error inspection, hundred percent inspection and immediate action.

SMED

Since the retooling or replacement of machines or tools takes time and thus leads to a loss of productivity, the "Single Minute Exchange of Die" (tool change in the single-digit minute range, SMED ) aims to avoid downtimes or bottlenecks during production . This is achieved by separating work steps that require the system to stand still and those that can be carried out while production is running.
