The purpose of this group assignment is to make familiar students with the key business processes within organizations and the role and operation of information systems in supporting these business processes.
Part A focuses on:
Case Study 01: (30 marks)
Last year the Hi-Fi Manufacturing Company purchased over $20 million worth of office equipment under its “special ordering” system, with individual orders ranging from $10,000 to
$60,000. Special orders are for low-volume items that have been included in a department manager’s budget. The budget, which limits the types and dollar amounts of office equipment a department head can requisition, is approved at the beginning of the year by the board of directors. The special ordering system functions as follows:
A purchase requisition form is prepared and sent to the purchasing department. Upon receiving a purchase requisition, one of the five purchasing agents (buyers) verifies that the requester is indeed a department head. The buyer next selects the appropriate supplier by searching the various catalogs on file. The buyer then phones the supplier, requests a price quote, and places a verbal order. A pre-numbered purchase order is processed, with the original sent to the supplier and copies to the department head, receiving, and accounts payab le. One copy is also filed in the open-requisition file. When the receiving department verbally informs the buyer that the item has been received, the purchase order is transferred from the open to the filled file.
Once a month, the buyer reviews the unfilled file to follow up on open orders.
The receiving department gets a copy of each purchase order. When equipment is received, that copy of the purchase order is stamped with the date and, if applicable, any differences between the quantity ordered and the quantity received are noted in red ink. The receiving clerk then forwards the stamped purchase order and equipment to the requisitioning department head and verbally notifies the purchasing department that the goods were received.
Upon receipt of a purchase order, the accounts payable clerk files it in the open purchase order file. When a vendor invoice is received, it is matched with the applicable purchase order, and a payable is created by debiting the requisitioning department’s equipment account. Unpaid invoices are filed by due date. On the due date, a check is prepared and forwarded to the treasurer for signature. The invoice and purchase order are then filed by purchase order number in the paid invoice file.
Checks received daily from the accounts payable department are sorted into two groups: those over and those under $20,000. Checks for less than $20,000 are machine signed. The cashier maintains the check signature machine’s key and signature plate and monitors its use. Both the cashier and the treasurer sign all checks over $20,000.

Case Study 02: (20 marks)
The Cyclone Manufacturing Company makes vacuum cleaners. Processing of production orders is as follows: At the end of each week, the production planning department prepares a master production schedule (MPS) that lists which vacuum cleaner models and quantities are to be produced during the next week. A production order preparation program accesses the MPS and the operations list (stored on a permanent disk file) to prepare a production order for ea ch vacuum cleaner model that is to be manufactured. Each new production order is added to the open production order master file stored on disk.
determine which materials need to be released to production. All materials are bar-coded. Factory workers work individually at specially designed U-shaped work areas equipped with several machines to assist them in completely making a vacuum cleaner. Factory workers scan the bar-codes as they use materials. To operate a machine, the factory workers swipe their ID badge through a reader. This results in the system automatically collecting data identifying who produced each model of vacuum cleaner and how much time it took to make them.
Once vacuum cleaner is finished, it is placed in a box. The last machine in each work cell prints a bar-code label that the worker affixes to the box. The packed and sealed vacuum cleaners are then sent to the warehouse.
Prepare a data flow diagram of all operations described.
