Consider the following multi-step process.

Activity 1 is done by worker A and takes 4 minutes per unit.

Activity 2 is done by worker B and takes 5 minutes per unit.

Activities 3 and 4 are done by worker C and take 3 minutes and 5 minutes per unit, respectively.

5 Assume that you decide to assign the additional worker to activity 4 and release worker C from this activity (to let worker C focus only on activity 3). If the new resource takes 5 minutes to complete activity 4, the new process capacity is [ Select ] ["7.5", "15", "12", "20"] units per hour.

6: Assuming that processing times are irrespective of which worker completes the activities, if you want to improve the process capacity without hiring an additional worker, you can take [ Select ] ["activity 3", "activity 4"] from worker C and reassign it to [ Select ] ["worker B", "worker A"] .

7: The capacity of the process after making the adjustment in Part 6 equals [ Select ] ["15", "12", "20", "7.5", "8.57"] units per hour.

Again, consider the original scenario (before making the latter adjustment to the process).

8: If the firm adopts a make-to-order approach, the customer's order lead time equals to [ Select ] ["14", "5", "8", "17"] minutes.

9: If the firm adopts an assemble-to-order approach, the customer's order lead time equals [ Select ] ["8", "5", "14", "17"] minutes. Hint: In the assemble-to-order environment, all the steps prior to assembly are completed before the customer order. The customer order triggers the assembly sub-process.
