Knowledge Check 1

Question 1Process Flow Diagram for Completing a Transaction with an Additional Worker All steps (A, B, C, D, and E) in the below process are necessary to complete each transaction or unit. Task times are shown for each step. A second worker has been hired to duplicate task D. Now transactions that have been through task C go to any one of the two workers on task D. The product still requires the five steps (A, B, C, D, E).

Refer to the Process Flow Diagram with an Additional Worker. Assume the entire process is running at the pace of the bottleneck. Consider only task D, with both workers performing task D. What is the capacity utilization for task D?

A. 100 %

B. 60 %

C. 50 %

D. 40 %

Question 2Process 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. Assume that the entire process is running at bottleneck pacing. Consider only task A, in isolation from the rest of the process. What is the approximate labor utilization at task A?

A. 5 %

B. 33 %

C. 42 %

D. 83 %

E. 100 %

A. 12 minutes

B. 26 minutes

C. 31 minutes

D. 36 minutes

E. None of these answers are .

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 the entire system (all steps). What is the entire system’s minimum cycle time?

A. 4 minutes/unit

B. 12 minutes/unit

C. 5 minutes/unit

D. 10 minutes/unit

Question 5Process Flow Diagram for Completing a Transaction with an Additional Worker All steps (A, B, C, D, and E) in the below process are necessary to complete each transaction or unit. Task times are shown for each step. A second worker has been hired to duplicate task D. Now transactions that have been through task C go to any one of the two workers on task D. The product still requires the five steps (A, B, C, D, E).

Refer to the Process Flow Diagram with an Additional Worker. If the entire system (all processes) is operating at full capacity, what is the system cycle time?

A. 4 minutes/unit

B. 12 minutes/unit

C. 5 minutes/unit

D. 10 minutes/unit

Question 6Process 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. Assume that the process operates eight hours a day. What is its daily capacity, in units per day?

A. 13 units/day

B. 40 units/day

C. 48 units/day

D. 96 units/day

E. None of these answers are .

Question 7 INSTRUCTIONS

NOTE: To make your calculations as straightforward as possible in the following exercises, assume unless stated otherwise that:

There are sufficient transactions or inputs, so tasks are never starved.

Task times have negligible variability and, over time, workers neither speed up nor slow down.

There are no equipment breakdowns or maintenance.

When there are buffers shown in process flow diagrams, they are large enough to accommodate any amount of work in process (WIP).

Travel time and time to move transactions from one operation to another are negligible.

All operations run with 100% yield; that is, the operations produce no defective transactions.

All processes are in steady state; thus, you may ignore any startup effects.
