Spiral Model is a risk-driven software development process model. Apart from appealing advantages the prototype model has many disadvantages that are listed below-It is a time-consuming process or method as multiple prototypes might be needed until the client reaches the final requirements. Comparing frameworks allow you to have a better understanding of their advantages and disadvantages.

Disadvantages of Prototype Model. The Waterfall Model. The spiral model is an SDLC model that combines elements of an iterative software development model with a waterfall model.

Incremental Model in SDLC. When the Waterfall model was used for software development there was no recognised alternative for knowledge based work. What is Spiral Model.

What is RAD Model. The Waterfall model depends upon the sequential approach in which each stage should complete itself to start the next stage. Similarly we complete this picture in four increments.

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. Several waterfall model advantages and disadvantages are worth considering when there is a development approach to consider. Teams do not require.
