Based on the topics we have learned in this module, please read following mini case and answer the questions. For this hw assignment, you need to prepare word or pdf document.
The town of Eden Bay owns and maintains a fleet of vehicles. You are a systems analyst reporting to Dawn, the town’s IT manager.
Please read the case given in the following link. Based on a preliminary investigation, the town has decided to develop a new information system to manage maintenance costs more effectively, instead of outsourcing it to private firms. (The case can be found in the link:)
Now Dawn wants you to perform additional fact-finding to document the specific requirements for the new system. She stressed that user input is absolutely critical at this stage.
Continuing Case: Personal Trainer, Inc.
Personal Trainer, Inc. owns and operates fitness centers in a dozen Midwestern cities. The centers have 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 IT consultant, Susan Park, to help develop an information system for the new facility. During the project, Susan will work closely with Gray Lewis, who will manage the new operation.
During requirements modeling for the new system, Susan Park met with fitness center managers at several Personal Trainer locations. She conducted a series of interviews, reviewed company records, observed business operations, analyzed the BumbleBee accounting software, and studied a sample of sales and billing transactions. Susan’s objective was to develop a list of system requirements for the proposed system.
