Software Development V-Model

Question

Give a precise explanation of Software Development V-Model.

Answer 1

Many of the procedure models currently employed can be more generally connected or linked by the V-model where describes graphical arrangement of individual phases. It is as well a synonym for validation and verification.

The model is extremely simple and easy to comprehend. By the ordering of activities in time series and with abstraction levels the connection between development as well as test activities becomes clear. Oppositely laying activities harmonize one another that is, serve as a base for the test activities. Consequently, for instance, the system test is carried out on basis of results specification phase. The coarse view of model provides the impression that the test activities first start after the completion. But, in the depiction of the individual activities the preparatory work is frequently listed. So, for instance, the test plan as well as test strategy must be worked out immediately after the description of the requirements. However it can contribute extremely well to the structuring of software development process.

The demerit of the model is coarse division in constructive work (comprising the implementation) on left-hand side of and the more disparaging tasks on the right-hand side. Here as well the impression might develop that, after implementation phase, a ready product can be delivered. A planned-in elimination of defects and regression test is not certain.
