V-Model advantages:
                It is also called as verification and 
                validation Model.
                This means the verification and validation
                will be done side by side.
                It emphasies the strict process flow to 
                develop a quality product.
                The errors occured in any pahse will be
                corrected in that phase itself.
V-Model disadvantages:
                It needs lot of resources and money.
                It needs an established  process to 
                implement.
                It can be implemented by only some big
                companies.

No its wrong the waterfall is waaaaaaaaay better:).

V Model stands for verification and validation

Since it is a rigorous, measurable and predictive process, 
it is mostly used for complex projects.
 It constantly measures the productivity, efficiency and 
quality of the software by reporting on test case creation, 
coverage, test execution progress and defects. It helps to 
maintain rigor in the testing process and handles multiple 
testing cycles for System, Integration, and final 
Acceptance. 
Using V Model side by side Validation can be done.

Disadv:
It can be used only in MNC's.. 
Costly one
