The Willowbrook School staff has accepted your systems design and your design specifications. Your group recommended installing a server and three personal computers as clients on a local area network. Two of these personal computers will be new units, the third will be an existing machine purchased very recently. The network will include a backup unit. An existing laser printer will be accessible by any of the three PCs. Microsoft Access will be used to develop the billing system. You are now benefiting from the 15 hours a week of volunteer time from one of the parents who is assisting you with the programming and testing.

Tasks

1. Application Testing - Design the testing required for the billing system. You should consider program, integration, and system testing in your test plan.
2. Changeover Methods - In an earlier case study, a preference was expressed for a transition to the new system utilizing a direct cutover method, timed around the move from one academic year to the next. All fixed fee billing for an academic year is completed in April and commences in July for the following academic year. Drop-in AfterCare billing continues for the month of May, and a final bill is issued during the second week of June, the week after classes end. Do you think this is feasible? Would you recommend another method for the transition?
3. Documentation - Based on the prototype screens you created in Case Study: System Design, create user documentation.
4. Data Conversion - Develop a data conversion plan that specifies which data items must be entered, the order in which the data should be entered, and which data items are the most time-critical.
