Toyota Production System (TPS) is a kind of production method by using continuous kaizen to eliminate all kinds of muda thoroughly. TPS is based on two concepts including Just In Time (JIT) and Jidoka. TPS is a practical operation that emphasize on more implementation than the theory and more effect or output than process. Since the knowledge of TPS is implicit in nature, it is difficult to recognize TPS and to practice TPS successfully. Through this practical research of A-Team, the researcher expects to search for necessary conditions for effective operation and to point out the key successful factors of TPS. Then the researcher has some suggestions to those enterprises, which intend to implement TPS successfully as follows: ● The top management who has accurate sensation of implementing TPS should lead ahead and fully support all activities. Furthermore, the top management is willing to authorize his foremen and workers to adjust production activities when it is required, and tolerate the loss incurred by inadequacy. ● Choose appropriate TPS leader and establish a group to lead the TPS implementation. The whole members will be induced to participate by means of team self-improvement and training. ● In order to learn the implicit knowledge of TPS, an experienced instructor is indispensable.
