The history of Kaizen begins after World War II when Toyota first implemented quality circles in its production process. Word “kaizen”, where “kai” = change “zen” = good, simply means “change for better”. In English kaizen typically means measures for implementing continuous improvement. Kaizen is an approach to activity organisation based on common sense, self-discipline, order and economy. Kaizen method is a strong contributor and fundamental part of a lean production process model in lean manufacturing.
At the end of the project, Kaizen can be used to achieve a continuous improvement culture.
