8. Waterfall Model Advantage – it allows for departmentalization and managerial control – Each phase of development proceeds in strict order, without any overlapping or iterative steps.iterative Disadvantage – it does not allow for much reflection or revision Once an application is in the testing stage, it is very difficult to go back and change something that was not well-thought out in the concept stage.
