Case Study – Discount Appliances (5 pointseach)
Until now, the owner, Bob, kept the business records on hispersonal computer. He created a simple database to keep track ofinventory, but it is not always up-to-date. He also developedspreadsheets to track expenses and payroll. The business has grownand Bob wants to install a new computer system to handle allbusiness functions.
Bob recently asked you to helphim plan a system for Discount Appliances. You used anobject-oriented approach to create a model of the businessfunctions and actors involved.
Now Bob wants you to do a “makeor buy” analysis. Specifically, you will look into the pros andcons of in-house development versus purchase of a software package.Your research indicates that the most popular appliance shoppackage is offered by a vendor called ApplianceData. In your lastmeeting, Bob said that tangible savings for a new system would behard to measure, but improved customer care, better servicedepartment records, and increased productivity are expected. Bobestimates that these benefits will add up to about $6,000 per year,whether the system is developed in-house, or purchased fromApplianceData.
You decide to compare relative costs to establish a total cost ofownership (TOC) over the useful life of the system. Based on yourresearch, you put together the following summary:
In-house development option
ApplianceData software package option
