Systems Development Life Cycle (SDLC) or sometimes just (SLC) is defined by the U.S. Department of Justice (DoJ) as a software development process, although it is also a distinct process independent of software or other information technology considerations. It is used by a systems analyst to develop an information system, including requirements, validation, training, and user ownership through investigation, analysis, design, implementation, and maintenance. SDLC is also known as information systems development or application development. An SDLC should result in a high quality system that meets or exceeds customer expectations, within time and cost estimates, works effectively and efficiently in the current and planned information technology infrastructure, and is cheap to maintain and cost-effective to enhance. SDLC is a systematic approach to problem solving and is composed of several phases, each comprised of multiple steps:

    * The Software concept - identifies and defines a need for the new system
    * A requirements analysis - analyzes the information needs of the end users
    * The architectural design - creates a blueprint for the design with the necessary specifications for the hardware, software, people and data resources
    * Coding and debugging - creates and programs the final system
    * System testing - evaluates the system’s actual functionality in relation to expected or intended functionality.
