This strategy is based on efficiencies achieved by decreasing wastes by receiving inventory of goods just as needed in a production process, and not before. It is also known as the Toyota Production System (TPS). The older “just-in-case strategy” involved producers carrying large inventories in case higher demands had to be met. The JIT differs from the older Just-in-case strategy in that it does not hold safety stock and operates with low inventory levels. Efficiency is thus automatically built in by reducing inventory costs. This method therefore requires producers to forecast their demand accurately.

The nation was rebuilding itself with the constraints of a lack of cash to finance large production, a lack of space to build factories and to store inventory and finally a lack of natural resources. As a result of these constraints, the Japanese had to “lean out” their processes by building smaller factories and keeping only as much inventory as was required in a process and ensuring quick return on investments to be able to purchase addition materials.
