WaterFall Model advantages:
It is a linear sequestial model
It is very simple model to implement
It is the first model.
It needs very few resources to implement
Disadvantages:
In this model there is no back tracking.
For example if any error occured an any
stage of software development,it cann't be
corrected in that build.
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.

Answer / mercy
In the traditional waterfall model, testing is done at the
end of the life cycle. The errors found at the later stages
are very expensive to fix. This has given an idea to V
model where in verification and validation are done at each
stage of SDLC to avoid errors/defects getting cascaded to
the other level. In other words V model aims for Stage
containment.

Answer / ashu
Hi
waterfall: in this model we can't possible to add new
requirements in middle if we add entire work once again
start from starting.
V-Model:This model is mapping between development and
testing team means.. verification and validation done

Answer / prathyusha
water fall model is sequential model it is easy to implement as it is a step by step model after completion of one face next face is called so we can fix defects in early stage only
disadvantages
it is suitable for only small projects
if we want change any requirements in the middle of project it is not possible
