What is 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, it 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.
Comparison between Agile model and other models in Software Engineering
Software development models are various processes or methods that are chosen for project development depending on the objectives and goals of the project. Agile is a popular model among these development models because it is flexible and adapts quickly to changes. It focuses on delivering small, usable parts of the software regularly, which allows for continuous feedback and improvements. This approach ensures that the final product meets user needs more accurately and is developed efficiently.
