This may involves adding, deleting, and changing pieces relative to the original system. The techniques used to complete the phases may be used in BPR.1-3FAST Systems Analysis Phases•Scope Definition Phase•Is the project worth looking at?•What are the parameters of this project?•Problem Analysis Phase•Is a new system worth building?•What is the problem and can a new system resolve them?•Requirements Analysis Phase•What do the users need and want from the new system?•Logical Design Phase•What must the new system do?•Decision Analysis Phase•What is the best solution?1-4Tasks for the Scope Definition Phase of Systems AnalysisSteering body– a committee of executive business and system managers that studies and prioritizes competing project proposals to determine which projects will return the most value to the organization and thus should be approved for continued systems development.
