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

For analysis, the primary focus is on discovery and understanding. The purpose is to understand at a detailed level the needs of the users. This can be based on existing systems and procedures or based purely on the desired business processes. The focus should not be on the solution system but instead on understanding the business need.

For design, the focus changes from understanding to thinking about a viable solution. The 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.

For implementation, the focus is on building a robust system. The activities of this phase are oriented towards taking the design and building a high quality working system. Also included in this phase are the support or ancillary activities needed to train users, convert data, and fine-tune the working environment.
