In this manner, what is waterfall model with example?

Waterfall model is an example of a Sequential model. In this model, the software development activity is divided into different phases and each phase consists of series of tasks and has different objectives. In waterfall, development of one phase starts only when the previous phase is complete.

what is the meaning of waterfall model? The waterfall model is a classic approach in software development that describes a linear and sequential development method. It consists of five to seven phases, each phase is defined by different tasks and objectives, whereby the entirety of the phases describes the life cycle of the software up to its delivery.
