The homework about System Analysis and Design
First question: Write one page that distinguishes among the fundamental purpose of analysis phase, design phase, and the implementation phase?
Second: Describe a system project that might have three iterations might used fro the project?
Third: There are at least two approaches to system development, a variety of life cycles, and a long list of techniques and models that are used in some approaches but not in others. Consider why this is so. Discuss these possible reasons, indicating which are the most important: The field is so young; such different needs; there are so many types of systems; and people with widely different backgrounds are developing.
