Last week, your boss, Susan, asked you to help her plan the new information system project. Susan knows that you have completed several information systems courses at the local college, and that you have studied project management tools and techniques. Specifically, she wants you to get ready for the next set of systems development tasks, which will be requirements modeling for the new system. Yesterday, Susan called you into her office to discuss the specific tasks she wants you to perform. After meeting with Susan, you sit down and review your notes. She wants you to treat the set of tasks as a project, and to use project management skills to plan the tasks. Here is what she suggested to you as a work breakdown structure, including the duration she estimated for each task: First, you need to meet with fitness center managers at other Personal Trainer locations (5 days). After these meetings, you can conduct a series of interviews (5 days) When the interviews are complete, two tasks can begin at the same time: you can review company records (5 days) and observe business operations (8 days). When you have reviewed the records and observed business operations, you can analyze the BumbleBee accounting software (7 days) and study a sample of sales and billing transactions (your student ID second last digit days, if zero, then 4 days). After completing the analysis and studying the sales transactions, prepare a report for Susan (1 day) A. Transform this task list into a Gantt Chart B.
