In this model customer can respond to each built.It is easier to test and debug during a smaller iteration.This model is more flexible – less costly to change scope and requirements.Generates working software quickly and early during the software life cycle.The process continues till the complete system is achieved.

A working version of software is produced during the first module, so you have working software early on during the software life cycle.Įach subsequent release of the module adds function to the previous release.

Each module passes through the requirements, design, implementation and testing phases.

Cycles are divided up into smaller, more easily managed modules.

Multiple development cycles take place here, making the life cycle a “multi-waterfall” cycle.

In incremental model the whole requirement is divided into various builds.

Not suitable for the projects where requirements are at a moderate to high risk of changing.

Poor model for long and ongoing projects.

Not a good model for complex and object-oriented projects.

Once an application is in the testing stage, it is very difficult to go back and change something that was not well-thought out in the concept stage.Waterfall model works well for smaller projects where requirements are very well understood.In this model phases are processed and completed one at a time.This model is simple and easy to understand and use.In this model the testing starts only after the development is complete. This type of model is basically used for the project which is small and there are no uncertain requirements. In a waterfall model, each phase must be completed fully before the next phase can begin.Prescriptive models are used as guidelines or frameworks to organize and structure how software development activities should be performed, and in what order. A prescriptive model prescribes how a new software system should be developed.A prescriptive process model is a model that describes 'how to do' according to a certain software process system.
