SYSTEM DOCUMENTATION TECHNIQUES – DATA FLOW DIAGRAMS AND FLOWCHARTS
Narrative #1
Jack E. Bagbaga has worked for the past month trying to document the major business information flows at Starducks, a wholesaler of balut in Sto. Tomas, Batangas. Upon completing his personal interviews with cash receipts clerks, Jack asks you to develop a comprehensive DFD and document flowchart for the cash receipts system. Jack’s narrative of the system follows:
Customer payments include cash received at the time of purchase and account payments received in the mail. At day’s end, the treasurer endorses all checks and prepares a deposit slip for the checks and the cash. A clerk then deposits the checks, cash, and deposit slip at the local bank each day. When checks are received as payment for accounts due, a remittance slip is included with the payment. The remittance slips are used to update the accounts receivable file at the end of the day. The remittance slips are stored in a file drawer by date.
Every week, a cash receipts report and an aged trial balance are generated from the data in the accounts receivable ledger. The cash receipts report is sent to the management. A copy of the aged trial balance by customer account is sent to the credit and collections department.
