What are the dimerits of waterfall model?

In waterfall model, once we come out of the phase, there is no chance of modifying it again. This is one of the major drawback for waterfall model.


What is the diffference between waterfall model and modified waterfall model?

Modified waterfall model verified and validate the user requirements for every phase. Meanwhile, waterfall did not, it only verify and validate user requirement at the end of the phase.


What is the difference between waterfall and Evolutionary process model?

The waterfall model is a linear and sequential approach to software development, where each phase must be completed before the next one begins, making it difficult to accommodate changes once a phase is finished. In contrast, the evolutionary process model is iterative and allows for incremental development, where requirements and solutions evolve through collaboration and feedback, enabling adjustments throughout the project. This flexibility in the evolutionary model facilitates continuous improvement and adaptation to changing requirements, whereas the waterfall model's rigidity can lead to challenges in dynamic environments.


Deference between classical waterfall model and iterative waterfall model?

Major difference between waterfall and iterative model is that waterfall model has a linear process in which full product is available after the last phase, while incremental model full product is available after several such phases.
