Systems Development Life Cycle
Systems Development Life Cycle consists of 6 major phases and to help the cycle along it is necessary to develop the project through a development team. The development team consists of users, system analysts, programmers, and technical specialists (Rainer & Turban, 2009). The first stage in the SDLC is the system investigation stage which consists of a feasibility study of either the technical, economic, behavioral or organizational aspect of the business. The feasibility study determines if anything will be done. The 2nd stage is system analysis which is the examination of the business problem that the organization plans to fix. It identifies the information requirements that the solution must satisfy. System design is the 3rd stage and this stage describes how the system will accomplish this task. The logical and physical design systems are integrated in this stage. After these three stages if it is determined a restructure will be done in-house then programming occurs which involves constructing software and translating the design specifications into computer codes. The 5th stage is the testing stage which very thoroughly tests the new system to make sure desired results are being obtained. The final stage is the implementation stage which is converting the old system to the new system. The three major typical conversions used are direct, pilot, and phase. Of course once the life cycle has been reached by these six stages it is important to keep the new system going, this is done through operation and maintenance which debugs, updates, and adds new functions. The SDLC is an important aspect to develop a successful business (Rainer & Turban, 2009).
