What is Spiral Model ? Spiral Model is a risk-driven software development process model . It is a combination of waterfall model and iterative model . Spiral Model helps to adopt software development elements of multiple process models for the software project based on unique risk patterns ensuring efficient development process. Each phase of spiral model in software engineering begins with a design goal and ends with the client reviewing the progress. The spiral model in software engineering ... The spiral model is a systems development lifecycle (SDLC) method used for risk management that combines the iterative development process model with elements of the Waterfall model. The spiral model is used by software engineers and is favored for large, expensive and complicated projects. What is Spiral Model ? The spiral model is a software process model that couples the iterative nature of prototyping with the controlled and systematic aspects of the linear sequential model . Barry Boehm mentioned the Spiral model in this paper (1986). The spiral model is also known as meta- model since it encompasses all other life cycle models. In this Spiral Model in Software Engineering , you will learn defination, why Spiral Model , phases with steps, differences, advantages and disadvantages.
