Systems Analysis and Design

1. Describe the six of the systems life cycle.
2. Discuss how problems or needs are identified during Phase 1, preliminary investigation.
3. Explain how the current system is studied and new requirements are specified in Phase 2, systems analysis.
4. Describe how a new or alternative information system is designed in Phase 3, systems design.
5. Explain how new hardware and software are acquired, developed, and tested in Phase 4, systems development.
6. Discuss how a new information system is installed and users are trained in Phase 5, systems implementation.
7. Describe Phase 6, systems maintenance, the systems audit and ongoing evaluation, to see if a new system is doing what it's supposed to.
8. Describe prototyping and RAD.
