What are the drawbacks of classical waterfall model? How are they rectified in other variants of the classical waterfall model?
Drawbacks of classical waterfall model:
In the classical waterfall model, each phase must be completed fully before the next phase can begin. At the end of each phase, a review takes place to determine if the project is on the right path and whether or not to continue or discard the project. The drawbacks are:
1) This type of model is basically used for the for the project which is small and there are no uncertain requirements.
2) In waterfall model phases do not overlap.
3) There are no feedbacks paths.
4) Difficult to accommodate change requests.
5) Inefficient error corrections.
The iterative waterfall model can be thought of incorporating the necessary changes to the classical waterfall model to make it usable in practical software developments projects. The main change brought about by iterative waterfall model to the classical waterfall model is in the form of providing feedback paths from every phase to the preceding phase.
