Written assignment




Draw a flowchart for a process of interest to you, such as a quick oil-change service, a factory process you might have worked in, ordering a pizza, renting a car or truck, buying products on the Internet, or applying for an automobile loan. Identify the points where something (people, information) waits for service or is held in work-in-process inventory, the estimated time to accomplish each activity in the process, and the total flow time. Evaluate how well the process worked and what might be done to improve it. Write up your conclusions and submit them as your assignment. If necessary, submit your flowchart as well.








Each bank teller workstation is forecasted to process 400 transactions (the end-item) on Friday. The bank is open from 9 a.m. to 7 p.m. on Friday with 90 minutes for lunch and breaks. Three teller windows are open on Friday. A work-study analysis reveals that the  breakdown of the transaction mix is 40 percent deposits, 45 percent withdrawals, and 15 percent transfers between accounts. A different form is used for each type of transaction, so there is one despots slip per deposit, one withdrawal slip per withdrawal, and two transfer slips per transfer.


1.     How many transfer slips are needed on Friday?


2.     How many withdrawal slips are needed on Friday?


3.     Deposit slips are delivered every second day. If the on-hand balance of deposit slips is 50 at this bank, how many deposit slips should be ordered?


4.     What is the end-item and component part in this bank example?


5.     What are the implications of having too many or too few deposit, withdrawal, and transfer slips? Explain
