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.
