The conventional V model was suited for Waterfall software development process. Iterative V Model is what we follow at HyTech Professionals. Iterative test process is best suitable for projects where development is done by one team and testing is done by an independent team.

Iterative test process consists of many iteration and every iteration consists of phases.
Each iteration has one release and all phases of V model are executed in one iteration. This leads to better quality release as changes done in one iteration are tested and complete system is tested again for any break point that crept in because of implementation in current iteration. In every iteration, percentage activity of phase is decided based on specification change scope.

The figure below shows the iterative testing process.
