what is advantages and disadvantages of the Waterfall Model
and V-Model

Answer Posted / 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.
