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. 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. Overview The spiral model is a risk-based software development approach. It guides a team to adopt components of one or more process models, such as incremental, waterfall, or evolutionary prototyping, based on the particular risk patterns of a given project. The spiral model is one of the best software development life cycle models due to the following properties: Risk management is present in the model . The Spiral model is also popular due to its ability to adapt to changes. Frequent ...
