Iterative Waterfall Model | Software Engineering

In Iterative waterfall model, the feedback paths are provided from every phase to its preceding phase. In practice, it is not possible to strictly follow the classical waterfall model for software development work. In this context, we can view the iterative waterfall model as making necessary changes to the classical waterfall model so that it becomes applicable to practical software development projects.
