The V-Model

The V-Model is a project management approach used in system development to ensure quality and thorough testing. It visually resembles a "V," with development activities on the left side, where requirements are defined and the system is built, and testing activities on the right side, corresponding to each development phase. As development progresses downward, testing plans are created, and as the project moves upward, testing is performed to verify each component. This structured linkage helps identify issues early and ensures that each part of the system is tested against its specific requirements, promoting reliable and well-validated results.
