Since opening its dorrs in Hawaii two years ago, Oriental trading has enjoyed tremedous success. Oriental Trading purchases textiles from Asia and resells them to local retail shops. To keep up with the strong demand, Oriental Trading is expanding its local operations, including a new information system to handle the tremendous increase in purchases. The following is a summary of your interviews with department supevisors who interact with the acquisition/payment system:

A purchase requisition is sent from the inventory system to sky Ishibashi, a puchasing department clerk. Sky prepares a purchase order using the vendor and inventory files and mails it to the vendor. The vendor returns a vendor acknowledgment to Sky indicating receipt of the purchase order. Sky then sends a purchase order notification to Elei Mateaki, an accounts payable clerk. When the receiving department accepts vendor goods, the inventory system sends Elei a receiving report. Elei also receives invoices from the various vendors. He matches the invoices with the purchase order notification and receiving report and updates the accounts payable master file. Elei then sends a payment authorization to the accounting department. There, Andeloo Nonu prepares and mails a check to the vendor. When the check is issued, the system automatically updates the accounts payable master files and the general ledger.
