Most of the process models presently used can be more usually joined by the V-model where the ‘V’ signifies the graphical arrangement of the individual phases. The ‘V’ is as well a synonym for verification and validation.

The model is much simple and simple to understand. By ordering of actions in the time sequence and with abstraction levels the connection connecting development and test activities becomes apparent. Oppositely laying actions complement one other that is, serve as the base for test activities. Therefore, for illustration, the system test is taken out on the basis of the outcomes specification phase. The coarse view of model provides the impression that the test activities first start after the implementation. However, in the description of the individual actions, the preparatory work is generally listed. Therefore for illustration, the test plan and test strategy must be worked out instantly after the definition of the requirements. Nonetheless it can contribute very well to the structuring of software development method.
