V-Model software development life cycle

The V-Model is a software development life cycle that emphasizes the relationship between development and testing. It is a variation of the Waterfall model and consists of four stages, namely Requirements, Design, Implementation, and Testing. Each stage has a corresponding testing phase, and the V-Model ensures that the testing process is integrated into every stage of software development. The V-Model is advantageous as it provides a clear framework for software development and testing, but it may not be flexible enough to accommodate changes. Overall, the V-Model is a reliable and efficient software development life cycle for projects with well-defined requirements and a fixed budget.
