symptoms rather than the underlying problem RequirementsGathering and Analysis Phase analysts de ne the problem and generate alternatives for solving it Design Phase analysts choose the solution that is the most realistic and offers the highest payoff for the organization Details of the proposed solution are outlined and the output of this phase is a document with exact speci cations for implementing the system including les and databases forms and reports documentation procedures hardware and software networking components and general system speci cations Implementation Phase the solution is transferred from paper to action and the team con gures the system and procures components for it Maintenance Phase the information system is operating enhancements and modi cations to the system have been developed and tested and hardware and software components have been added or replaced 2 In the Analysis Phase of the SDLC analyzing requirements is done from the perspective of the process and data once the models are created and design speci cations are con rmed with users analysts can start designing the system 3 4 Elements of Feasibility Analysis feasibility the measure of how bene cial or practical an info system will be to an organization should be measured continuously throughout the SDLC process feasibility study analyszes a proposed solution s feasibility and

solution will work in the organization and how internal and external customers will react to it ask oneself whether the information system is worth implementing d Scheduling feasibility whether the
