|
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?
|
If the requirements are well understood and well defined then predictive SDLC would be the best method. If the requirements and needs are uncertain then Adaptive SDLC would be the best method.
|
|
What is the objective of each phase of the SDLC? Describe each objective briefly.
|
Project planning – initiate, ensure feasibility, plan schedule, obtain approval for project
Analysis – understand business needs and processing requirements Design – define solution system based on requirements and analysis decisions Implementation – construct, test, train users, and install new system Support – keep system running and improve |
