The waterfall model of software engineering for the systems development life cycle model is the most popular version. Often considered classic approach to life cycle of systems development , linear and sequential waterfall model describes the development system. Waterfall development objectives are different for each stage of a development .Imagine a waterfall on the cliff of an alp. Water has flowed over the edge of a steep mountain side and has started walking down , it cannot turn back. It is same as the waterfall development. Once a phase of development is completed, there is no turning back when the development proceeds to the next phase.

• The rigidity of the model is easy to manage - Each stage has a specific distribution and review process.
• In this methodology phases are processed and completed one at a time and phases do not overlap.
• Waterfall methodology proceeding well for smaller projects where requirements are very well understood.

Disadvantages of waterfall methodology

• When an application is in the testing stage, it is very hard to turn back and change something, that was not well-thought out in the concept stage.
• No working software is produced until late during the life cycle.
• Uncertainty and the risk, very high.
• It is not a good methodology for complex and object-oriented
