| Aspect | Product Validation | Product Testing |
|---|
| Purpose | Ensures the product meets user needs and requirements | Identifies defects and verifies functionality |
| Focus | Customer requirements and usability | Technical performance and defect detection |
| Timing | During validation phase, often before release | Throughout development, especially before release |
| Methods | User acceptance testing, field testing | Functional testing, regression testing |
Product Validation focuses on confirming that the product fulfills user needs and requirements, ensuring it is fit for purpose. Product Testing, on the other hand, concentrates on identifying technical defects and verifying functionality. Both are essential but serve different stages and objectives in the product development lifecycle.
