V-Model

The V-Model is a sequential software development lifecycle model that illustrates a one-for-one relationship between major phases of development and corresponding test levels.

Key Characteristics:

  • Clear mapping between development stages and testing phases
  • Emphasis on early validation through corresponding tests at each phase
  • Structured approach from requirements specification to delivery
  • Focus on both verification (building the product right) and validation (building the right product)
  • Encouragement of continuous feedback throughout the process

The V-Model promotes thorough documentation and planning, ensuring that quality assurance is integrated into every phase of development.
