Incremental Model

In incremental model the whole requirement is divided into various builds. Multiple development cycles take place here, making the life cycle a“multi-waterfall” cycle.  Cycles are divided up into smaller, more easily managed modules.  Each module passes through the requirements,

Incremental model is an evolution of waterfall model. Multiple development cycles take place here, making the life cycle a “multi-waterfall” cycle.  Cycles are divided up into smaller, more easily managed iterations.  Each iteration passes through the requirements, design, implementation and testing phases.

§  More flexible – less costly to change scope and requirements.

§  Easier to test and debug during a smaller iteration.
