Under the JIT system, minimal inventory reduces all of the above costs. Because minimal inventory and highly accurate inventory records are critical under any manufacturing system, this chapter focuses on installing inventory tracking systems, which can then be used to pinpoint inventory problems and lead to smaller inventories. In addition, this chapter discusses the valuation of inventories, the physical inventory procedure, and inventory fraud.
