| Aspect | Design Verification | Design Validation |
|---|
| Purpose | Ensures the design meets specified requirements through testing and analysis | Confirms the final product fulfills user needs and intended use |
| Timing | During the development phase | After the product is developed and before release |
| Methods | Inspections, reviews, testing, analysis | User testing, field trials, real-world testing |
| Focus | Design correctness and compliance | Product effectiveness and user satisfaction |
While Design Verification checks if the design meets specified requirements during development, Design Validation ensures the final product performs effectively in real-world conditions. Both are essential steps in the product development process to deliver a reliable and user-centered product.
