Water Fall Model
Water Fall Model for Software Developement
In waterfall model, we proceed from one phase to the next in a sequential manner. Requirement Analysis, Design,Implementation, Testing,Deployment and Maintenance are the different sequential phases.That is once the requirement analysis is completed perfectly we proceed towards design phase. When the design is totally completed, the implementation of that design is performed by the coders. After completing the coding, the testing phase begins.The objective of testing is to uncover errors. The next is the deployment maintenance phase.Thus the waterfall model insists that proceed to the next phase only after completing previous phase perfectly. Water fall model is also known as classic life cycle model.
