Flowchart Case Study Project

The following problems (Flowchart Case Study Project) are based on the narrative provided for a fictional company, Order-and-Receive.com, which describes the sales process. You will complete each problem below based upon this narrative, providing full documentation of the process along with documented control matrix. Note: For all graphical drawings you may use Microsoft Visio, PowerPoint, Excel, or other drawing tools.

Company Narrative

Order-and-Receive.com, a fictitious company, sells a variety of consumer products through its Web site, Order-and-Receive.com. The companyís 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 Web site. The Web server requests the current 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 they want to purchase; the Web server edits the customer input for accuracy (e.g., ensures that all required fields have been selected or filled in) and sends the customerís list to the ERP system, where the requested items and quantities of inventory are allocated for the sale.


The ERP system sends back to the Web server the items and quantities that have been allocated, the Web server displays this information on the customerís screen. The customer verifies that the order is correct and completes the sale by entering their shipping/billing address and credit card information. The Web server edits this data for accuracy (e.g., 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 company 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 customerís screen. The Web server also notifies the ERP system that the sales has been completed, and the ERP system changes the status of the inventory from allocated to sold, prints a picking ticket & packing slip in the warehouse, and records on the enterprise database a sale and an account receivable from the credit card company.
