Concepts and features about poka-yoke systems: a literature review

Abstract

This paper has the purpose of analyzing methods, techniques and guidelines for the design, operation and maintenance of poka-yoke systems. In parallel it intends to contribute with concepts about what poka-yoke are and their classification. Therefore a literature review was made about systems poka-yoke concepts, poka-yoke systems classification, kinds of inspections, kinds of mistakes, the relationship between stability and statistical process control with mistake proofing systems, techniques and directions to design and manage poka-yoke. An analysis was carried out with each subject relating poka-yoke with the subject. At the end the absence of a poka-yoke management system was evident, because techniques for design, operation and maintenance aren’t consistent.
