ABSTRACT
Since I thought that explaining poka-yoke methods by means of examples would be extremely effective when it came to actually adopting a poka-yoke system, I asked some progressive companies that have already achieved considerable success to submit examples. In addition to expressing my sincere thanks to all those firms that have consented to the publication of their examples, I would like to list the names of those companies as a token of my gratitude.
