Spiral model: What is Spiral Model

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. The spiral model is a risk-driven software development process model that blends elements of other approaches based on the project's risk patterns. Learn about its history, characteristics, invariants, milestones, and applications from this Wikipedia article. The Spiral Model is a software development approach that involves iterative development with risk management. It is appropriate for large, complex, and high-risk projects, because it provides continuous improvement through multiple phases or spirals. Planning, prototyping, and feedback are the core principal of each stage in this model .
