Document Summary

Write a one-page paper that distinguishes among the fundamental purposes of the analysis phase, the design phase, and the implementation phase of the traditional predictive sdlc. During analysis, the focus is on understanding the details of the problem or need and not the solution system. The intent here is to figure out exactly what the system must do in order to support the business processes. In the design phase, the focus switches from understanding to thinking about a viable solution by configuring and structuring the new system components. The main purpose of design is to synthesize or develop a solution. The two layers of design are the architecture layer and the detailed module layer. At the architecture layer, the purpose is to think of the entire solution system and how it is structured. At the detailed design layer, the purpose is to think about the individual modules or classes and define the details of the executable code.
