IE 131 Homework Problems due Mar 12, 2008 (Chs 9 and 10) 9.7 The Purchasing Department is required to use the following paperwork procedure for each purchase order (PO) related to a company production order. The purchase order is the legal document used by the company to order raw materials and parts from vendors in specified quantities and to guarantee payment to the vendors upon delivery of the items ordered. The purchase order procedure is triggered by the release of a production order that has been authorized by top management for one of the company’s regular products. The production order indicates what product is to be produced, how many units, and when it is to be completed. To produce the product, the raw materials and component parts must be ordered in the correct quantities from suppliers (vendors). To initiate the purchase order procedure, a purchasing agent in the Purchasing Department fills out a blank purchase requisition form for each raw material or component part, obtaining the quantity information from the bill of materials for the product. The purchase requisition is an internal company document used to obtain approvals by several departments that are responsible for the product and/or its production. The purchase requisition is sent first to the Design Engineering Department where it is checked for any engineering changes that may have been made to the item ordered. The requisition is then sent from Design Engineering to the Manufacturing Engineering Department, which checks to make sure that a valid route sheet exists for the item. The route sheet is the process plan that indicates how the item is to be processed in the factory. From Manufacturing Engineering, the requisition is sent to the Production Control Department, which checks the requisition to make sure the quantity information and delivery date agrees with the production order. At each of these departments, the signature of the department manager is required in addition to the regular department employee who performed the check. It takes an average of three days in each department to obtain the necessary checks and approvals. After approval by Production Control, the purchase requisition is returned to the Purchasing Department, where it is used as the authorization to prepare the actual purchase order that will be sent to the vendor. The information on the purchase requisition is transcribed onto a blank purchase order form by the originating purchasing agent, and the PO is then signed by the manager of the Purchasing Department and mailed to the vendor. Each PO is sent in a separate envelope by first class mail, even though there are many vendors receiving more than one purchase order from the company. (a) Construct a form process chart for the current purchase order procedure. (b) Based on your form process chart, what are some changes that you would recommend? (c) Develop a revised purchase order procedure, documenting your revision in a new form process chart.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
