Detailed explanation-1: -In the spiral model, the major drawback is that additional functionalities are added later on.
Detailed explanation-2: -High cost-The spiral model is expensive and, therefore, is not suitable for small projects.
Detailed explanation-3: -The spiral model, initially proposed by Boehm, is an evolutionary software process model that couples the iterative feature of prototyping with the controlled and systematic aspects of the linear sequential model.
Detailed explanation-4: -In the spiral model, the phases are therefore not run through once step-by-step, but several times in a spiral shape. Although this cyclical repetition means that the project approaches the goals set comparatively slowly, the risk of a failed development process is decisively minimized thanks to the regular controls.
