Overview
The V-model is a system development model which is used to manage software development projects. It places emphasis on the processes and activities necessary to verify the quality and completeness of the final product. The V-model is represented as an inverted "V" which begins with system requirements and progresses through design, code, testing and finally maintenance. This model enables a systematic approach to be taken when developing a software system, and is useful in reducing costs and preventing errors. Its importance lies in its ability to trace any issues back to their source, allowing for quick resolution and efficient development.
