The key Difference between Verification & Validation
| Verification | Validation |
| Check to develop the right product or not in the developing phase | Check a developed product is right or not |
| Static testing | Dynamic testing |
| Quality assurance | Quality control |
| Execution of code does not happen in the verification stage | The execution of code happens in the validation stage |
| Verification is done before Validation | Validation is done after verification |
| In this, we can verify that the inputs follow the output | We can validate that the user accepts the product or not |
