Why choose waterfall over incremental model in software engineering? Flexibility to change in incremental model is Easy. Cost of Waterfall model is Low. Cost of incremental model is also Low. Testing is done in waterfall model after completion of all coding phase.
Why is waterfall model better than other models? The advantages of waterfall development are that it allows for departmentalization and control. A schedule can be set with deadlines for each stage of development and a product can proceed through the development process model phases one by one.
Why is waterfall model preferred? This model is simple and easy to understand and use. It is easy to manage due to the rigidity of the model – each phase has specific deliverables and a review process. In this model phases are processed and completed one at a time. Phases do not overlap.
What are the benefits of incremental development compared to the waterfall model? Compared to the waterfall model, incremental development has three important benefits: The cost of accommodating changing customer requirements is reduced. The amount of analysis and documentation that has to be redone is much less than that’s required with waterfall model.
