O`Brien Corporation is a midsize, privately owned, industrial instrument manufacturer supplying precision equipment to manufactures in the Midwest. The corporation is 10 years old and operates a centralized AIS. The administrative offices are located in downtown building and the production, shipping, and receiving departments are housed in a renovated warehouse a few blocks away. The shipping and receiving areas share one end of the warehouse. The marketing department consists of four sales representatives. Upon obtaining an order over the telephone, a sales person manually prepares a prenumbered, two part sales order. One copy of the order is filed by date and the second copy is sent to the shipping department. All sales are on credit, FOB destination. Because of the recent increase in sales, the sales representatives have not had time to check credit histories. As a result, 15% of credit sales are either late collections or uncollectible. The shipping department receive the sales order and packages the goods from the warehouse, noting any item that are out of stock. The terminal in the shipping department is used to update the perpetual inventory records of each item as it is removed from the shelf. The packages are placed near the loading dock door in alphabetical order by customer name. A shipping clerk signs the order, indicating that the order is filled and ready to send. The sales order is forwarded to the billing department, where two part sales invoices is prepared. The sales invoice is prepared upon receipt of sales order from the shipping department so that the customer is billed only for the items that were sent, not for back orders. Billing sends the customer`s copy of the invoice back to shipping , and shipping then inserts it into special envelope on the package in order to save postage costs. The carrier of the customer`s choice is then contacted to pick up the goods. In the past, goods were shipped within 2 working days of receipt of the customer`s order; however, shipping dates now average 6 working days. One reasons for this slippage is that two new shipping clerks are still undergoing training. Because these clerks have fallen behind, the two experienced clerks in the receiving department have been assisting them.The receiving department is located adjacent to the shipping dock, and many different carriers deliver merchandise daily. The receiving clerks share a computer terminal with the shipping department. The date, vendor and number of items received are entered upon receipt to keep the perpetual inventory records current. Hard copies of the changes in inventory (additions and shipments) are printed monthly. The receiving supervisor checks that the additions are reasonable and forward the printout to the shipping supervisor, who is responsible for the checking the reasonableness of the deductions from inventory (shipments). The inventory printout is stored in the shipping department by date. A complete inventory list is printed only once a year when entire inventory is counted. Required: a.
