| Outline of Final Research Achievements |
The Toyota Production System is well known in its technical aspects like leveled production, Just-In-Time production, and “Jidoka” for carrying out Kaizen to increase productivity and to decrease production cost. However, the Toyota Production System had its particular management system of productivity, closely linked to a part of the wage, called “productivity allowance”, worked up by Taiichi Ohno from 1948 to 1971. This productivity management system remained unknown for us, outsiders. Based on interviews with the company, this study elucidates in detail the institutional framework of this productivity management working with the wage system and the evolution of such management system from 1948 to 2011, emphasizing the fact that this productivity management system of Ohno was abolished in 2004.
