Since opening its doors in Newark five years ago, RBS Tech Inc. has enjoyed tremendous success. To keep up with the strong demand for network devices in New Jersey, RBS Tech Inc. is expanding its operations. At the heart of the expansion is the introduction of a new Web-based acquisition system to handle the tremendous increase in purchases. You have conducted several interviews with employees who will interact with the Web-based acquisition system. The following is a summary of your discussions. When an employee completes a purchase requisition form on the company's Web site, the system (e., Web-based acquisition system) receives the purchase requisition and prepares a purchase order using the information in the employee, supplier, and inventory files. The system also updates the purchase order file and sends the purchase order to a supplier via email. Once the supplier receives the purchase order, he or she checks the order and returns a supplier acknowledgment to the system via email, indicating receipt of the purchase order. Whenever the system receives the supplier acknowledgment, it generates a purchase order notification for further process. When the supplier ships goods, he or she also sends an invoice to the system via email. When the warehouse department accepts goods (shipped by the supplier), the department transfers a receiving report to the system. The system then matches the invoices with the purchase order notification and the receiving report and updates the accounts payable master file. The system also generates a payment authorization. Finally, based on the payment authorization, a payment (ie, check) is made to the supplier, and the system automatically updates the accounts payable file.
