Beta Products Corporation is a major vendor of office supplies, furniture, and equipment. Beta's sales representatives call on customers to ask them what they would like to order. Typically, a customer has a list of products that they want to buy, and they give this list (either in writing or verbally) to the sales rep. As soon as the sales rep leaves a customer's office, they type up the order and email it to the inbox of the sales order processing (SOP) clerk at Beta's local office. When the SOP clerk has time, they click on each new order in their inbox and carry out a series of steps to processes it before moving on to the next order: First, if the order items are in stock in the inventory database, the SOP clerk prepares a packing list form for all in-stock items in that order, which they print out and place on top of a pile of other packing lists in the warehouse office. . . . Next, if any of the ordered items are out of stock, the SOP clerk completes an electronic "out-of-stock notice form" and sends it to the inbox used by the Purchasing clerks. Then, the SOP clerk also notes what items are in stock and which are out of stock on an electronic. annotated customer order and forwards it to the Accounts Receivable inbox. Throughout the day, when a Purchasing clerk has time, they use the out-of-stock notice form to complete an electronic purchase order form, which is emailed to a supplier. Accounts Receivable clerks work their way through their inbox periodically, preparing printed invoices from the annotated customer orders and sending those invoices to the customer. At the Warehouse, when workers are ready to fill their next order, they grab the next packing list from the pile, find the corresponding items, print a shipping label, and place the items into boxes along with the packing list, seal the box, attach the shipping label, and leave the boxed order at the loading dock. Some time later in the day, the boxed order is picked up for delivery by UPS.
