IEEE Standard for System and Software Verification and Validation
Verification and validation (V\&V) processes are used to determine whether the development products of a given activity conform to the requirements of that activity and whether the product satisfies its intended use and user needs. V\&V life cycle process requirements are specified for different integrity levels. The scope of V\&V processes encompasses systems, software, and hardware, and it includes their interfaces. This standard applies to systems, software, and hardware being developed, maintained, or reused [legacy, commercial off-the-shelf (COTS), nondevelopmental items]. The term software also includes firmware and microcode, and each of the terms system, software, and hardware includes documentation. V\&V processes include the analysis, evaluation, review, inspection, assessment, and testing of products.
