The Waterfall model is developed by dividing the whole process into a few separate phases. Typically, each phase is designed with the simple logic that the outcome of the earlier phase is injected as the input for the next-level phase. By design, each phase of the waterfall mode, is expected to be signed off, before getting into the subsequent phase. It involves the deliverable artifact of each phase like design document, business requirement document, source code, test plan, etc.
The Waterfall model
Core phases
In a real-life scenario, this model behaves based on our imagination of water falling from top to the bottom, as in a waterfall. It is simply represented in the following diagram. With the similar concept, the Waterfall model is designed as follows with these...
