Is V Model better than Water Fall Model? If so how is it?

Rather than water fall method it is better to follow v model. one of the main reason for v model is cost effective as well as it is more convenient in developer and test engineer point of view, because its provides outstanding result for software development activities and at the same it is good for preparing test plan and test strategies.

1. Waterfall model is traditional where Testing comes in last phase while V model represent verification and validation .

2. Waterfall Model the tester role will take place only in the test phase but in V-Model role will take place in the requirement phase itself

3. Waterfall madel is a fixed process u can't make any changes in the requirement or in any phase.but in V-Model u can make any changes in the requirements

4. Waterfall model used only the requirements are fixed but V-model can be used for the any type of requirement(Uncertain requirement)

5. We can say waterfall model is mostly we use in product based application while for project based application V model is mostly used.

Yes ,V Model is far better than Water Fall Model because  there is no flexibility to go revert and only single stage testing that to by programmers in water fall model.

Where as in v model there are reviews in each and every phase such as reviews in analysis,reviews in design etc.

V-Model -

Testing Phase
Unit Low Level Design
Integration High Level Design
System SRS
UAT Business Requirements

In Waterfall model Need All Trascibility matrix before coding that is Time Taking and Complex for all cases , and Not Sure to Track All cases at once. in V model Each Level Like SRS, Design, Coding and testing as each Phase happens simultaneously So Defect will Find Out in Each Phase So, it is Cost Effective.
