Software VERIFICATION VS VALIDATION

Verification takes place before validation, and not vice versa. Verification evaluates documents, plans, code, requirements, and specifications. Validation, on the other hand, evaluates the product itself.

Verification:  was the product built right?

Validation: was the right product built?

In simple language, we can say that Verification is the pre-testing reviews, walk throughs, evaluations of the documents, plans and code, whereas Validation is the actual testing, finding the defects in the software.
