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.
