We go for waterfall model if the requirement of a problem are reasonably well understood for ex In existing employ payroll system ,if the payroll computing mechanism has to be changed we go for waterfall model
cleanroom software engineering implements waterfall model.
online event management system.
Any project for which complete and consistent requirements are available is amenable to the waterfall model. In general, this will tend to be a very small project. The only large projects that are amenable to the waterfall model would be projects of re-engineering an existing system, therefore all the requirements are known before you start the process.
The reason is that the waterfall model only handles requirements in the first phase of development. In the presence of requirements or technical uncertainty you want to have some kind of iterative process in place, i.e. RUP, Agile, RAD, etc. When requirements uncertainty is present you will start coding and then discover that requirements need to be reviewed or rewritten -- in the waterfall model there is no other phase where requirements get revised.

we can take real life examples for water fall model like automobile companies make cars and bikes. when they are building a car, the requirments are fixed, predecided. there will be no change in the requirments during the process of building a car. Once we complete a stage, we proceed to the next one. if there is any change in requirments come then we have to go back and make those changes. then we have to change our complete system that requirs extra time and extra money. this is a major disadvantage of water fall model.
