What is System Development Life Cycle?

The System Development Life Cycle (SDLC) is a process used by businesses and information technology (IT) professionals to develop, manage, and maintain computer-based systems. It is a structured process that includes planning, designing, developing, testing, deploying, and maintaining the system. The SDLC model provides a comprehensive framework for creating efficient and effective systems that meet customer specifications in the most cost-effective manner possible.The SDLC begins with analyzing customer requirements to determine what needs to be built or enhanced. This involves gathering data about current processes as well as identifying specific goals for the new system. Once this information has been gathered, it can be used to define the system’s scope and objectives. Following this step is designing the system architecture which outlines how data will flow through various components of the system including hardware platforms and software applications. After designing the architecture comes developing a prototype of the system which will allow users to interact with it so any changes or improvements can be made before going into production. During this process robustness testing is done which looks at how well different components interact with each other while performance testing checks how quickly files are read from disk or sent over networks etc. Once all tests have passed successfully then implementation can begin which means rolling out final version of software application into production environment where real users start using it.
