Practical Project on MIS 13-9 A customer who buys a Sears Roebuck appliance, such as a washing machine, can also purchase a three-year service contract for an additional fee. The contract provides repair service and parts at no cost to the specified appliance, through an authorized Sears service provider. When a person with a Sears service contract needs to repair an appliance, such as a washing machine, you must call the shop’s Repair and Parts department to schedule an appointment. The department makes the appointment and provides the caller with the approximate date and time of the appointment. The repair technician arrives during the designated time window and diagnoses the problem. If this is caused by a defective part, the technician replaces it if he brings one with him or asks for it to Sears. If the piece is not in stock in Sears, Sears orders it and provides the customer with the approximate date of arrival of the piece. The piece is sent directly to the customer. Once it arrives, the customer should call Sears to schedule a second appointment in which a repair technician should replace the part that was ordered. This process is very long. It can take up to two weeks for the first repair visit to occur, another two weeks to receive the ordered part and one more week for the second repair visit to occur in which the ordered part is installed. Create a diagram of the existing process. • What is the effect of the existing process on Sears’ operational efficiency and customer relationships? • What changes could be made to make this process more efficient? • Create a diagram of the new improved process. • How might information systems support these changes?
