Problem: Consider the following production process
The process consists of 38 steps and operates at a cycle time of 0.84 min/unit. Their most error prone operation is step 8. If each worker checks the work of the previous steps and there are on average roughly 116 units of inventory between step 8 and the end of the process, equally distributed across the remainder of the process, what is the average information turnaround time for a defect made at step 8 (in minutes)?
