Problem: Companies such as IBM and Ingersoll-Rand have moved beyond JIT to JIT-II systems. In JIT-II systems, supplier sales representatives work on-site to monitor inventory levels and have access to current sales data and forecasts. The supplier representatives use this information to reorder goods automatically and meet production needs. Discuss the potential advantages and disadvantages of this arrangement. What special controls, if any, should be developed to monitor JIT-II systems?
