Validation and Verification in Modeling

In modeling, validation and verification are distinct processes serving different purposes. Validation entails assessing the extent to which a conceptual model accurately represents the intended use cases envisioned by the developer. It examines how well the model captures reality and incorporates essential features, ensuring alignment with the developer’s objectives. Conversely, verification involves confirming that a model implementation faithfully realizes the intended use cases when executed with real data, software, and hardware. In essence, verification verifies whether the code adheres to specifications, while validation evaluates whether the specifications meet customer requirements. In the DSAIL metamodeling process, initial stages focus on design verification, while later stages emphasize code generation and testing for verification purposes.
