Why Spiral Model is called Meta Model?

The Spiral model is called a Meta-Model because it subsumes all the other SDLC models. For example, a single loop spiral actually represents the Iterative Waterfall Model.

  1. The spiral model incorporates the stepwise approach of the Classical Waterfall Model.
  2. The spiral model uses the approach of the Prototyping Model by building a prototype at the start of each phase as a risk-handling technique.
  3. Also, the spiral model can be considered as supporting the Evolutionary model – the iterations along the spiral can be considered as evolutionary levels through which the complete system is built. 

What is Spiral Model in Software Engineering?

The Spiral Model is one of the most important Software Development Life Cycle models. The Spiral Model is a combination of the waterfall model and the iterative model. It provides support for Risk Handling. The Spiral Model was first proposed by Barry Boehm. This article focuses on discussing the Spiral Model in detail.

What is the Spiral Model?

The Spiral Model is a Software Development Life Cycle (SDLC) model that provides a systematic and iterative approach to software development. In its diagrammatic representation, looks like a spiral with many loops. The exact number of loops of the spiral is unknown and can vary from project to project. Each loop of the spiral is called a phase of the software development process....

What Are the Phases of the Spiral Model?

The Spiral Model is a risk-driven model, meaning that the focus is on managing risk through multiple iterations of the software development process. It consists of the following phases:...

Risk Handling in Spiral Model

A risk is any adverse situation that might affect the successful completion of a software project. The most important feature of the spiral model is handling these unknown risks after the project has started. Such risk resolutions are easier done by developing a prototype....

When To Use the Spiral Model?

When a project is vast in software engineering, a spiral model is utilized. A spiral approach is utilized when frequent releases are necessary. When it is appropriate to create a prototype When evaluating risks and costs is crucial The spiral approach is beneficial for projects with moderate to high risk. The SDLC’s spiral model is helpful when requirements are complicated and ambiguous. If modifications are possible at any moment When committing to a long-term project is impractical owing to shifting economic priorities....
