Answer / poonam

In water fall model what we do is
1)req.analysis
2)design
3)coding
then (4) testing
5)implementation
means at the end of coding phase we go for testing,not
before that.
but in V model that is varification and validation
we do
1)req.analysis + testing (varification)
2)design + testing (varification)
3)coding +testing (validation)
4)testing (validation)
y? varification in req.analysis & design phase.Bcz in these
two phases we cannot test a project in running conditions,
bcz at this stage we have documents with us.
y? validation while coding and testing. Bcz in these phases
we have our project in running condition, means we can
execute a program using computer.so at these stages we can
validate our project according to SRS.
