Systems Analysis and Design in a Changing World 2-1 Chapter 2 – Approaches to System Development Review Questions 1. What are the five phases of the SDLC? The five phases of the SDLC are the planning phase, analysis phase, design phase, implementation phase, and support phase. 2. What characteristics of a project call for a predictive approach to the SDLC? What characteristics of a project call for an adaptive approach to the SDLC? Predictive: Projects are well understood—technology is well known; user requirements are well known; development methodology is well known; project team is experienced and familiar with the system; and there are few known risks. Adaptive: Projects are not well understood—technology is new or unfamiliar; requirements are not very clear; team is not experienced with the type of system or methodology. 3. How is the SDLC based on the problem-solving approach described in Chapter 1? The five phases are similar to the steps in the general problem-solving approach outlined in Chapter 1. First, the organization recognizes it has a problem to solve (project planning). Next, the project team investigates and thoroughly understands the problem and the requirements for a solution (analysis). Once the problem is understood, a solution is specified in detail (design). The system that solves the problem is then built and installed (implementation). As long as the system is being used by the organization, it is maintained and enhanced to make sure it continues to provide the intended benefits (support). 4. What is the objective of each phase of the SDLC? Describe each objective briefly. See Figure 2-3 page 40.
