Explain how the waterfall model of the SDLC controls the changes that occur during a project
The pure waterfall attempts to specify completely the requirements during the analysis phase, and then tries to "freeze" those requirements so that things do not change. Another solution is to have a modified waterfall so that additional analysis (i.e. specifying new requirements) can be done as the project progresses. However, neither situation is well suited to handle big changes during the life of a project.
