QUESTION 6 INSTRUCTIONS NOTE: To make your calculations as straightforward as possible in the following exercises, assume unless stated otherwise that: 1. There are sufficient transactions or inputs, so tasks are never starved. 2. Task times have negligible variability and, over time, workers neither speed up nor slow down. 3. There are no equipment breakdowns or maintenance. 4. When there are buffers shown in process flow diagrams, they are large enough to accommodate any amount of work in process (WIP). 5. Travel time and time to move transactions from one operation to another are negligible. 6. All operations run with 100% yield; that is, the operations produce no defective transactions. 7. All processes are in steady state; thus, you may ignore any startup effects. A 5 mins./unit C-D-E 4 mins./unit 12 mins./unit 5 mins./unit B 10 mins./unit Process Flow Diagram for Completing a Transaction (such as a loan application, a call at a call center, an order in a fast food restaurant, a customer at a bank, or a unit being processed). Consider the following process flow diagram for completing a transaction unit. All tasks or steps (A, B, C, D, and E) are necessary to process and complete the transaction. Each task employs a single employee. Exact task times, in minutes/unit, are shown at each step. For example, it takes exactly 4 minutes to complete task C. Refer to the Process Flow Diagram. Consider only task A, in isolation from the rest of the process. What is task A's cycle time? CA. 10 minutes/unit B.5 minutes/unit CC. 12 minutes/unit
