Supplier Participation. Kanban system requires supplier commitment in providing fast services to provide
effective supply of raw materials. Basically Kanban system only requires minimum level of inventories in the
production line where the inventories number should be equal with the production numbers. Therefore
supplier commitment play an important role in order to ensure production lines operates smoothly and
efficiently. There are five important criteria when choosing suppliers includes quality, willingness to work
together, technical competence, geography, and price. The aim of just in time (hereafter termed as JIT) is to
eliminate stocks rather than move them to another point in the supply chain. And, again, the way to achieve
this is through the co-operation (Donald, 2003). The Japanese Kanban process of production is sometimes
incorrectly described as a simple just-in-time management technique, a concept which attempts to maintain
minimum inventory. The Japanese Kanban process involves more than fine tuning production and supplier
scheduling systems, where inventories are minimized by supplying these when needed in production and
work in progress in closely monitored (Donald, 2003).
