Business Requirements:

XYZ Company sells computer equipment to federal government agencies.  When a federal agency needs to purchase computer equipment from XYZ, it issues a purchase order against a standing contract previously negotiated with the company.  XYZ holds several standing contracts with various federal agencies.  When a purchase order is received by XYZ’s contracting office, the contract number referenced on the purchase order is entered into the contract database.  Using information from the database, the contracting officer reviews the terms and conditions of the contract and determines whether the purchase order is valid.  The purchase order is valid if the contract has not expired, the type of equipment ordered is listed on the contract, and the total cost of the equipment does not exceed the predetermined limit.  If the purchase order is not valid, the contracting officer returns the purchase order back to the requesting agency with a letter explaining why the purchase order cannot be filled, and a copy of the letter is filed.  If the purchase order is valid, the contracting officer enters the purchase order number into the contract database and marks the order as outstanding.  The purchase order is then sent to the order filling department.  At the order filling department, the inventory is checked for each item ordered.  If any items are not in stock, the order
filling department creates a report listing the items not in stock and attaches it to the purchase order.  All purchase orders are forwarded to the warehouse where the items in stock are pulled from the shelves and shipped to the customer.  The warehouse then attaches to the purchase order a copy of the shipping bill listing the items shipped and sends it to the contracting officer.  If all items were shipped, the contracting officer closes the outstanding purchase order record in the database.  The purchase order, shipping bill, and exception report (if any), are then filed in the contract office.
