Personal Trainer, Inc

Background

Michael Acheampong has completed a preliminary investigation and performed the following fact-finding tasks and below is the fact-finding summary. Now, he will use the results to develop a logical model of the proposed information system.

Fact-Finding Summary

· A typical center has 300–500 members, with two membership levels: full and limited. Full members have access to all activities. Limited members are restricted to activities they have selected, but they can participate in other activities by paying a usage fee. All members have charge privileges. Charges for merchandise and services are recorded on a charge slip, which is signed by the member.

· At the end of each day, cash sales and charges are entered into the BumbleBee accounting software, which runs on a computer workstation at each location. Daily cash receipts are deposited in a local bank and credited to the corporate Personal Trainer account. The BumbleBee program produces a daily activity report with a listing of all sales transactions.

· At the end of the month, the local manager uses BumbleBee to transmit an accounts receivable summary to the Personal Trainer headquarters in Chicago, where member statements are prepared and mailed. Members mail their payments to the Personal Trainer headquarters, where the payment is applied to the member account.

· The BumbleBee program stores basic member information, but does not include information about member preferences, activities, and history.

· Currently, the BumbleBee program produces one local report (the daily activity report) and three reports that are prepared at the headquarters location: a monthly member sale report, an exception report for inactive members and late payers, and a quarterly profit and- loss report that shows a breakdown of revenue and costs for each separate activity.

During the interviews, Michael received several “wish list” comments from managers and staff members. For example, managers want more analytical features so they can spot trends and launch special promotions and temporary discounts. Managers also want better information about the profitability of specific business activities at their centers, instead of bottom-line totals.

Several managers want to offer computerized activity and wellness logs, fitness coaching for seniors, and various social networking options, including e-mail communications, fitness blogs, Facebook, and Twitter posts. Staff members want better ways to handle information about part-time instructors and trainers, and several people suggested using scannable ID cards to capture data.

DESIGNING THE DATABASE

After evaluating various development strategies, Susan prepared a system requirements document and submitted her recommendations to Cassia Umi, Personal Trainer’s president. During her presentation, Susan discussed in-house development and outsourcing options. She did not feel that a commercial software package would meet Personal Trainer’s needs.

Based on her research, Susan felt it would be premature to select a development strategy at this time. Instead, she recommended to Cassia that an in-house team should develop a design prototype, using a relational database as a model. Susan said that the prototype would have two main objectives: It would represent a user-approved model of the new system, and it would identify all systems entities and the relationships among them. Susan explained that it would be better to design the basic system first, and then address other issues, including Web enhancements and implementation options. She proposed a three-step plan: data design, user interface design, and application architecture. She explained that systems analysts refer to this as the systems design phase of a development project.

Cassia agreed with Susan’s recommendation, and asked her to go forward with the plan.

Tasks

1. Prepare a context diagram for the new system.

Personal Trainer, Inc. owns and operates fitness centers in a dozen Midwestern cities. The centershave done well, and the company is planning an international expansion by opening a new“supercenter” in the Toronto area. Personal Trainer’s president, Cassia Umi, hired an ITconsultant, Susan Park, to help develop an information system for the new facility. During theproject, Susan will work closely with Gray Lewis, who will manage the new operation.BackgroundWorking as an IT consultant for Personal Trainer, Susan Park used data and process modeling tools to create a logical model of the proposed information system. Now she wants to build an object-oriented view of the system using O-O tools and techniques. Before you perform the following tasks, you should review the information and background in Chapters 1 and 2, and the fact-finding summary of the case provided in Chapter 4.Tasks1.Identify possible actors and use cases involved in Personal Trainer’s operations.Continuing Case:Personal Trainer, Inc.
