There aren't hard and fast phases in the waterfall model, but there are some generally accepted standards. Which model can be selected if user is involved in all the phases of SDLC? Every Waterfall project has. to plan the various stages of developing an application. Once a project passes the testing phase it is ready to be released to the end user. In this phase, the system design is prepared which specifies hardware and system requirements, such as data layers, programming languages, network infrastructure, user interface etc. Each phase must be completed before the next phase can begin with no overlap between the phases. The Spiral Model is generally favoured for large scale, expensive, and complicated projects. The model is described to be a breakdown of project actives into linear sequential phases, where each phase depends on the product and deliverables of the subsequent phase. This linear development methodology sprang from the Waterfall approach. For a construction project, the deployment phase is when the building is fully ready for occupants. In other projects, tweaks to the environment are done to address issues, such as optimizing air conditioning in a new building. It is where the tested product goes live and is often referred to as the go-live phase.
