Systems Analysis


In this chapter you will learn more about the systems analysis phases in a systems development project—namely, the scope definition, problem analysis, requirements analysis, and decision analysis phases. The first three phases are collectively referred to as systems analysis. The latter phase provides transition between systems analysis and systems design. You will know that you understand the process of systems analysis when you can:
