The software development life cycle, known as the SDLC, ensures an application meets the needs of its users. Success of the software depends upon utilizing all five steps of the SDLC for as long as the application is in use.
The research phase is the initial step of the SDLC, and it's at this point the user's needs are determined. After compiling a list of all needed elements, the design phase commences. After the software is designed and coded, it needs to tested and reworked when necessary. The software is then ready to go live, which is known as the implementation phase. The last phase is maintenance, which requires staff ready and able to handle errors, other problems and upgrades throughout the application's lifespan.
