"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 prioritizing customer satisfaction, widens the use of mistake-proofing in their hierarchical scale. In this sense, the technique leaded to the creation of software poke-yokes which are simple, specific, attributes, acts early, responsive, and can be used for new purposes.

The following pages of this paper will present two devices of mistake-proofing. I will define each device separately and...
