Consider the following two production processes making an electronic component for a navigation system. Both processes consist of 25 steps and operate at a cycle time of 0.75 min/unit. Their most error prone operation is step 12. Process I: Has a final inspection at the end of the process and has 128 units of inventory between step 12 and the inspection.

Process II: has each worker check the work of the previous steps and has 240 units of inventory between step 12 and the end of the process, roughly equally distributed across the remainder of the process. What would be the information turnaround time for a defect made at step 12?
