The peculiarity of the approach is the emphasis on testing and validation of systems during development. Tests are conducted in parallel with the process of product creation itself. The principle itself inherits the basic approach of cascade development. The process is carried out step by step, there is a clear plan of action, a strict requirement specification is made. But at the same time, tests are conducted and, if errors are found, they are immediately corrected regardless of the stage of development.
The peculiarity of this software development methodology is that tests are already conducted at early stages of creation, and you can proceed to a new stage only when all errors are eliminated. At the new stage, the tests analyze not only the new stage, but all the previous stages as well. This allows you to control the interrelation of components and their performance.
Advantages of V-model
- The number of errors in software architecture is minimized.
