What Is the Systems-Development Life Cycle and Why Is It Important to the Selection of an Information System?

According to Dictionary, the Systems Development Life Cycle is any logical process used by a systems analyst to develop an information system. SDLC is important in the selection of an information system because it results in a high quality system that meets or exceeds customer expectations.

SDLC models are important when developing complex systems that require large teams of architects, analysts, programmers and testers. The various SDLC models include waterfall, rapid prototyping, incremental, spiral, fountain, build and fix, synchronize and stabilize and rapid application development (RAD). According to Computerworld, the most common SDLC model is the waterfall model, which consists of the following stages: project planning, systems analysis, systems design, implementation, integration and testing, installation and maintenance. Each step of the model helps information systems analysts assess the progress of the development project and decide whether to select one information system over another. When a project requires millions of codes or process automation, SDLC can be used to complete the project within time and cost estimates and to ensure that the system works effectively and efficiently in the current and planned information technology infrastructure. The system development process requires careful planning, execution and management to ensure that the software developed meets standards of quality and performance.
