Verification and validation ensure compliance with industry regulations and product quality. The Verification activity consists of confirming, through objective evidence, that the input requirements are fully and correctly implemented. The Validation activity consists of confirming, based on evidence derived from a set of activities, including Verification, Risk Management, Usability Analysis, etc., that the requirements for the intended use are met.
Verification in both hardware and software development cycles involves all project phases: requirements, architecture, implementation, integration. These verifications are supported by tools and automated tests to ensure the accuracy and reliability of the entire process.
