verifikációvalidáció

Verifikációvalidáció refers to the distinct but related processes of ensuring a system or product meets its specified requirements and that it fulfills its intended purpose. Verification is the process of checking that the development of a product, system, or component is done correctly according to its specifications. It answers the question, "Are we building the product right?" This involves activities such as reviews, inspections, and various forms of testing that compare the work product against documented requirements or standards. For instance, in software development, verification might involve code reviews to ensure adherence to coding standards or unit tests to confirm that individual components function as designed.

Validation, on the other hand, is the process of determining whether the product or system meets the needs of the user and the market. It answers the question, "Are we building the right product?" Validation focuses on the end-user's perspective and the system's effectiveness in its operational environment. This includes activities like user acceptance testing, beta testing, and market studies. For a software application, validation would involve demonstrating to stakeholders that the final product solves the problem it was intended to solve and is usable by its target audience. While verification focuses on internal consistency and adherence to design, validation focuses on external utility and fitness for purpose. Both are crucial steps in a comprehensive quality assurance process.
