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 Trainers president, Carol Cassie, 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. Background Susan and Gray finished their work on the user interface, input, and output design. They developed a user-centered design that would be easy to learn and use. At this point, Susan turned her attention to the architecture for the new system. Susan wanted to consider Enterprise Resource Planning, total cost of ownership, scalability, web integration, legacy systems, processing methods, and security issues. She also needed to select a network plan, or topology, that would dictate the physical cabling and network connections, or consider a wireless network. When all these tasks were completed, she would submit a system design specification for approval.
