Difference between Verification and Validation

Verification and validation are the two activities/phases that together lead to the whole software testing. Let’s see the difference between the two-

Verification is the process of evaluating the artifacts of software development in order to ensure that the product being developed will comply to the standards.Validation is the process of validating that the developed software product conforms to the specified business requirements.
It is a static process of analysing the documents and not the actual end product.It involves dynamic testing of a software product by running it.
Verification is a process oriented approach.Validation is a product-oriented approach.
Answers the question – “Are we building the product right?”Answers the question – “Are we building the right product?”
Errors found during verification require lesser cost/resources to get fixed as compared to be found during the validation phase.Errors found during validation require more cost/resources. Later the error is discovered higher is the cost to fix it.
It involves activities like document review, test case review, walk-throughs, inspection etc.It involves activities like functional testing, automation testing etc.
