Consider the following two production processes making an electronic component for a navigation system. Both processes consist of 20 stations and operate at a cycle time of 1 minute/unit. Their most error prone operation is step 9.

Process 1: Has a final inspection at the end of the process and has about 300 units of inventory between step 9 and the inspection.
Process 2: Has each worker check the work of the previous steps and about 50 units of inventory between step 9 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 station 9?
