Exercise 5

JIT and Traceability of Costs
Assume that a company has recently switched to JIT manufacturing. Each manufacturing cell produces a single product or major subassembly. Cell workers have been trained to perform a variety of tasks. Additionally, many services have been decentralized. Costs are assigned to products using direct tracing, driver tracing, and allocation. For each cost listed, indicate the most likely product cost assignment method used before JIT and after JIT. Set up a table with three columns: Cost Item, Before JIT, and After JIT. You may assume that direct tracing is used whenever possible, followed by driver tracing, with allocation being the method of last resort.
