Forskellen mellem verifikation og validering
Difference Between Verification and Validation
Folk bliver ofte forvirrede mellem verifikation og validering. Faktisk er de ikke ens. Ifølge 4. udgave af Project Management Body of Knowledge, Validation: Sikkerheden for, at et produkt, en service eller et system opfylder behovene hos kunden og andre identificerede interessenter. Det involverer ofte accept og egnethed hos eksterne kunder. "Kontrast med verifikation". Verifikation: Evalueringen af, om et produkt, en tjeneste eller et system overholder en forskrift, krav, specifikation eller pålagt betingelse. Det er ofte en intern proces. "Kontrast med validering". I enklere vendinger er kravverifikation processen med at bekræfte, at systemkravene indeholder alle de nødvendige elementer af velskrevne krav. Kravvalidering er processen med at bekræfte, at systemet opfylder dets mål og fungerer efter hensigten. Verifikation handler om at kontrollere, om kravene er fuldstændige, korrekte og konsistente. Validering handler om at kontrollere, om systemet lever op til sine mål og fungerer efter hensigten.
People often get confused between verification and validation. Actually, they are not the same.
According to the 4th edition of the Project Management Body of Knowledge,
Validation: The assurance that a product, service, or system meets the needs of the customer and other identified stakeholders. It often involves acceptance and suitability with external customers. “Contrast with verification”.
Verification: The evaluation of whether or not a product, service, or system complies with a regulation, requirement, specification, or imposed condition. It is often an internal process. “Contrast with validation”.
In simpler terms, Requirements verification is the process of confirming that the system requirements contain all the necessary elements of well-written requirements. Requirements validation is the process of confirming that the system meets its objectives and functions as intended. Verification is about checking whether the requirements are complete, correct, and consistent. Validation is about checking whether the system meets its objectives and functions as intended.
