The waterfall model is a sequential project management process. Each phase of the project cascades into the next, down following like a waterfall. The five phases of the waterfall model are requirements, design, implementation, verification, and Maintainance. These phases follow in linear order, where the next phase can’t begin until the work of the previous phase has been completed. Using waterfall project management, you can highlight the project development process in a linear sequential flow. These creative and fully customizable PowerPoint templates can help you to build effective and engaging project process flow presentations with ease.
