Abstract
The waterfall model is a Systems Development Life Cycle model (SDLC) and was the first process model to be introduced. The waterfall model is easy to understand and use, it is a stage gate model which means that the model consists of stages and gates. Each phase consists of one stage and one gate and in each phase there are some pre-determined activities and requirements. The current phase has to be completed before the next phase can begin and to end a phase it has to pass a gate. A stage is the activities A gate is a review that determine whether or not a project can continue. It is named the waterfall model because The waterfall model consists of six different stages, 1) Requirements Gathering and Analysis, 2) Systems Development, 3) Systems Implementation and Coding, 4) Testing, 5) Deployment, 6) Systems Operations and Maintenance.
which are widely used for software development but it is also a widely criticized model. The model is often criticized for the late detection of defects in the process and how to handle change requests among other things but the model is easy to
