Incremental Model – Big Picture

An evolutionary process model is that which deliver some product at the end of each iteration of software development.

In the Incremental process model , classical waterfall model is applied repeatedly because the drawback of waterfall model is that it cannot rectify any major change at the later stage of the software development.The incremental process model focus on delivering a working product at each iteration and each iteration pass through
