Check out this fantastic waterfall! It just keeps going!
Because the life cycle steps are described in very general terms, the models are adaptable and their implementation details will vary among different organizations. The spiral model is the most general. There is various software development approaches defined and designed which are used during development process of software, these approaches are also referred as Software Development Process Models. Each process model follows a particular life cycle in order to ensure success in process of software development.
One such process used in Software Development is The Waterfall Model. Waterfall model was first Process Model to be introduced and followed widely in Software Engineering to ensure success of the project. In The Waterfall model, the whole process of software development is divided into separate process phases. The phases in Waterfall model are: Requirement Specifications phase, Software Design, Implementation and Testing & Maintenance. All these phases are cascaded to each other so that second phase is started as and when defined set of goals are achieved for first phase and it is signed off, so the name Waterfall Model.
