A clerk in the accounting department periodically reviews the inventory records in order to determine which items need reordering. When she notes that the quantity on hand has fallen below a pre-established reorder point, she prepares a prenurnbered purchase requisition in two copies. One copy of the PR is placed in a chronological file until the matching purchase order is received. The original PR is sent to the purchasing department, where a buyer (1) decides on a suitable supplier by reference to a supplier le and (2) prepares a prenurnbered purchase order in four copies. The original copy of the purchase order is signed by the purchasing manager and mailed to the designated supplier. The second copy of the PO is returned to the inventory clerk in the accounting department, who (a) pulls the matching second copy of the PR from the temporary le (where it had been filed chronologically), (b) posts the ordered quantities to the inventory records, and (c) les the purchase requisition and purchase order together numerically. The third copy of the PO is forwarded to the receiving department where it is led numerically to await the receipt of the ordered goods. The fourth copy of the PO is led numerically, together with the original copy of the purchase requisition, in an open purchase order file. When the invoice from the supplier arrives, this last copy will be forwarded to the accounts payable department. Notes: 1. The process is totally manual. The only information medium used is paper. 2. There are three departments involved. Divide the owchart by these into columns. 3. Define the process (symbol) in terms of inputs and outputs. Thus, it is ok to show a process symbol with more than one activity occurring. Your assignment is to owchart the purchase order documents from the point where I left off with the purchase requisition
