Aquamarine Company is a manufacturer of heavy machinery. The company uses pre-numbered materials requisition forms to control the release of raw materials into production (this is a MANUAL system). Three copies of the requisition forms are generated in the production department. The supervisor of the production department must authorize each materials requisition before it can be used to withdraw materials from the stores department. The supervisor can either mark the requisitions approved or not approved, based on his review of the approved materials master file. If the requisition is approved, one copy is retained by the supervisor for his records (and filed by requisition number), one copy is sent to the stores department (filed by requisition number) and the third copy is sent to the accounting department (filed by requisition number). If the requisition is not approved, all three copies are maintained by the supervisor of the production department (filed by number).

Sometimes a materials requisition cannot be filled with materials already available onsite. In this case, it is sent to Peggy in Procurement, who verifies: (1) the requisition is properly approved, (2) the requesting manager has the budget approval for ordering, and (3) there is an authorized vendor for the item(s) to be ordered. If the answer to all three of these is yes (i.e., the requisition is properly approved, there is budget for the order, and there is a vendor for the items), Peggy creates a three-part purchase order. Copy one is sent to the vendor via email. Copy two is sent to the requesting manager, and copy three is maintained in Peggys files by date until the purchase order is filled. If the answer to (1) or (2) is no, the requisition is returned to the manager. If the answer to (3) is no, Peggy sends the requisition to her supervisor with a note to start the process of finding a vendor.
