System Request: A request presents a brief summary of a business need, and it explains how a system that supports the need will create business value. Feasibility Analysis: Can we build it Will it provide business value If we build it, will it be used 2.)

Analysis Strategy: An analysis of the current system (as-is system) and its problems and then ways to design a new system (to-be system) Requirements Gathering: Through interviews, questionnaires, and input from project sponsor and many other people, this leads to the development of a concept for a new system. Analysis Models: The set of models typically includes models that represent the data and processes necessary to suppo
