Verification typically involves reviews and meetings to evaluate
documents, plans, code, requirements, and specifications. This can be
done with checklists, issues lists, walkthroughs(A 'walkthrough' is an informal meeting for evaluation or informational purposes. Little or no preparation is usually required.), and inspection
meetings. Validation typically involves actual testing and takes place
after verifications are completed. The term 'IV & V' refers to
Independent Verification and Validation.
