Do you know the difference between verification and validation of a product?

Verification and validation are two different stages of product testing:

• Verification — checking that the product is developed correctly, meaning it meets the specified requirements and specifications. This process involves evaluating intermediate development results (e.g., code reviews, module testing).

• Validation — checking that the product meets user expectations and needs, meaning it solves the set tasks. Usually, this is the final testing of the product in real conditions or with the participation of end-users.

Example: verification — checking that a function works according to the technical specifications; validation — checking that this function is truly useful and convenient for the user.
