DisAdvatages
1. Inflexible partitioning of the project into distinct
stages makes it difficult to respond to changing customer
requirements.
2. The lifecycle can take so long that the original
requirements may no longer be valid by the time the system
is implemented.
3. Estimating time and costs is difficult for each
stage.

Advantages:
Model is simple.
Easy to understand.
Disadvantages:
Time consuming as the testing process starts the last

Answer / sreenu
actually the waterfall model is a dependent model.
so in the every phase depends upon another phase.So after
completion one phase(sdlc) then goes to next phase.
for example after completion of coding testing should
happen.it should dependent.
If u want to add any new requirement it should be so cost
effective.
advantage is cheaper.

2- Time Consuming.
3- We cannot go back, if the design phase has gone wrong, things can get very complicated in the implementation phase.
4- Small changes or errors that arise in the completed software may cause a lot of problem.
5- Until the final stage of the development cycle is complete, a working model of the software does not lie in the hands of the client.
