In systems engineering, information systems and software engineering, the systems development life cycle, also referred to as the application development life-cycle, is a process for planning, creating, testing, and deploying an information system. The systems development life cycle concept applies to a range of hardware and software configurations, as a system can be composed of hardware only, software only, or a combination of both. There are usually six stages in this cycle: requirement anal Software Development Life Cycle (SDLC) is a process used by the software industry to design, develop and test high quality softwares. The SDLC aims to produce a high-quality software that meets or exceeds customer expectations, reaches completion within times and cost estimates. SDLC is the acronym of Software Development Life Cycle. Software development life cycle (SDLC) models show the ways to navigate through the complex and demanding process of software building. A project's quality, timeframes, budget, and ability to meet the stakeholders' expectations largely depend on the chosen model. Today, there are more than 50 recognized SDLC models in use The Software Development Life Cycle (SDLC) is the software development world's spellcheck — it can flag errors in software creation before they're discovered (at a much higher cost) in successive stages. But it's much more than that, of course: SDLC can also lay out a plan for getting everything right the first time Waterfall model is the models of software development life cycle, where software development process is divided into different phases. The output of one phase works as input for the next phase. The development of next phase starts only when the previous phase is complete. The Waterfall model is also known as the linear sequential model
