157 JIT Results If your business model will support JIT, there are impressive cost savings available. In one not atypical installation, the com- pany was able to cut the number of vendors by 67%.The restructured production process reduced rework and scrap by 44%. Machine setup times dropped by 47%.The key was that total inventory was cut almost in half, reduced by 46%.

The ability to understand and substitute for each other allows for wider participation in brain- storming work improvement suggestions. In fact, JIT grew out of TQM management ideas. JIT vendors are selected based on delivery time and quality, since JIT depends on short purchas- ing cycles and good quality to prevent redos. JIT also gives managers a more direct tracing of costs such as setup costs that were formerly classified as overhead. JIT accounting entries are even designed to cut costs through an approach known as backflush costing. Backflush Costing Uses In traditional product costing, costs track sequentially. Transaction recording is timed with the physical sequences of purchases and production. Such a system is expensive to oper- ate and maintain, especially if costs are tracked to individual operations and products, as in job order costing. JIT production uses an alternative recording method known as backflush costing. This approach delays recording cost data until production is complete. Backflush costing looks to remove non-value-added activities from costing systems. Typically two trigger points are set to record cost data, when raw materials are purchased and when finished goods are either completed or sold. Thus, the cost of tracking work in process disappears. For many companies, this is a major benefit, since most managers do not find it worthwhile to spend money to track costs through work in process, finished goods, and cost of goods sold that can be captured through other means. This is especial- ly true when production is under statistical process controls. Think back to the discussion in Chapter 6 of the effects of absorption versus variable costing. In just-in-time production systems, inventory of work in process is typically small com- pared with the costs of goods produced and sold. Using back- flush costing means that when inventories are small, the majori- ty of production costs flow into cost of goods sold and not into inventory accounts.
