The operations vice president of Security Home Bank is investigating the efficiency of the bank's operations. She is concerned about the costs of handling routine transactions at the bank and would like to compare these costs at the bank's various branches. If the branches with the most efficient operations can be identified, their methods can be studied and replicated elsewhere. While the bank maintains meticulous records of wages and other costs, there has been no attempt to show how those costs are related to the various services provided by the bank. The operations vice president has asked for your help in conducting an activity$-$based costing study of bank operations. In particular, she would like to know the cost of opening an account, the cost of processing deposits and withdrawals, and the cost of processing other customer transactions.
