Describe the differences between the waterfall model and the spiral model.In case of a waterfall model, the stages are in a sequence. Once one stage is over, the process moves to the next phase. Hence, accommodating changes in the middle is difficult. On the other hand, accommodating changes in requirement is easy in a spiral model. This is because we need not start from the beginning because prototypes are created in every phase. Waterfall model is best suited for large projects. Spiral model is best suited in case of complex projects.
Secondly, because of the sequential nature of Waterfall model, if any mistake is done in between of a phase, we may need to begin from scratch. On the other hand, in spiral model because the prototypes are tested at the end of each phase, mistakes can be handled.
