Good Buy, Inc. (a fictitious company) sells a variety of consumer pro- ducts through its Web site, good-buy.com. Good Buy's IT infrastructure consists of a front-end Web server that interacts with customers and a back-end ERP system that manages the inventory and performs other typical ERP functions. The sales order process begins when a customer logs on to the good-buy.com Web site. The customer requests the com- pany catalog and the Web server obtains the current Good Buy online catalog from the ERP system, which sends the catalog to the Web server, and the server displays it to the customer. The customer selects the items and quantities that he or she wants to purchase, the Web server edits the customer input for accuracy (eg, ensures that all required fields have been selected or filled in) and sends this list on to the ERP system, where the requested quantities of inventory are allocated for the sale. The ERP sends back to the Web server the quantities that have been allocated, and the Web server displays this information on the customer's screen. The customer verifies that the order is correct and completes the sale by entering his or her shipping and credit card information. The Web server edits this data for accuracy (eg., ensures that all required fields have been selected or filled in and that the length of the entered credit card number is correct) and sends the credit card information and amount of the sale on to the credit card company. The credit card com- pany sends back a verification number, and the Web server notifies the customer that the sale has been completed by displaying a confirmation number on the customer's screen. The Web server also notifies the ERP system that the sale has been completed, and the ERP system changes the status of the inventory from allocated to sold, prints a pick- ing ticket or packing slip in the warehouse, and records (on the enterprise database) a sale and an account receivable from the credit card company.
