One of the main tools of the Toyota Production System(TPS) is Kanban system for Just-In-Time(JIT) production, in which each process produces only what is needed by the following process. Kanban is a well-known visualization tool which indicates which item, when, and how many to produce. Although Kanban system was introduced in Korea as early as 1980s, currently it is not widely used in Korean industry, partly because detailed procedure of its implementation has not been released to the practitioners. This paper aims to provide such a practical knowledge about how to implement the Kanban-based production systems, by explaining its details systematically; and introducing the case of automobile door sash manufacturer in Korea.
