Answer / vanithalatha

waterfall model is a linear sequential model in which
progress flows steadily downwards like a waterfall from one
phase to another phase.In waterfall model,coding will start
once all the requiremtns are fixed.so it is very difficult
for customer to give all the requirements at the initial
stage itself.Adding new reuirementsor changes isvery
expensive.The main disadvantage of waterfall model is if
any error is found in one phase, from there it wont go
forward untill unless that error got clarified from earlier
stages.

Hi,
Like Ramprasad said this is how the water fall model
works. But it has it's major disadvantages. If there is a
major change in the requirement like adding new
functionality or fixing the defect when the application is
in testing phase, then it will be very expensive to fix it.
So this is not really a successful model.

Answer / dev

water ever our frndz said it is write.but if we take any
model we are having both things advantage and disadvantage
like in this water fall model we have
ADVANTAGE: Easy to moniter d project and maintain.
DISADVANTAGE: if the customer need to add any feature in
middle of d project its not possible in this model.

mostly company use v-model means not exactly that model
similar type of approach they proceed. companies having
there own approach just these models are reference to
them.......

7) Maintenance

Answer / ram.polavarapu

analysis
design
coding and construction
testing and validations
release and maintenance

this model for small projects

by following the waterfall model we are not ensure the
quality of the application why because the testing is going
to conduct to fourth phase.
