"Defects arise because errors are made; the two have a cause-and-effect relationship. ... Yet errors will not turn into defects if feedback and action take place at the error stage"[Shingo, 1986, p. 82]
According to Shingo, there is a close relationship between defect and error. However, an error goes through a long process to become a defect. During this long process many action can be made to prevent the error to become a defect. Shingo and Deming found in this long process a chance to correct the errors made at the production or managerial level. They made up a system called “Poka-Yoke”, a Japanese name for mistake-proofing.
Shigeo Shingo, a Toyota industrial engineer, is indeed the founding father of the Poka-Yoke. A device expected to prevent defects, Poka-Yoke is extended to inspect the quality of products. Hence, the use of this technique cost Toyota no more than 150$ for each mistake-proofing device. The technique, indeed, reduced the cost of errors to a lower level at an inexpensive cost.
A technique which began in the 1960’s, poka-yoke is used widely by companies now a day around the world. Leading organizations throughout the world, seeking to promote quality ownership and p ...
