What are the disadvantages of Waterfall Model?
Answer:
1) Ironically, the biggest disadvantage is one of its greatest advantages. You cannot go back a step; if the design phase has gone wrong, things can get very complicated in the implementation phase.
2) Often, the client is not very clear of what he exactly wants from the software. Any changes that he mentions in between, may cause a lot of confusion.
3) Small changes or errors that arise in the completed software may cause a lot of problems.
4) 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. Thus, he is hardly in a position to inform the developers, if what has been designed is exactly what he had asked for.
