ISO 23247-2:2022 Digital Twin Validation Checklist

ISO 23247-2:2022 establishes a systematic, traceable, and auditable validation framework for digital twins, distinguishing validation (‘Are we building the right twin?’) from verification (‘Are we building the twin right?’). It mandates evidence-based assessment across multiple dimensions: conceptual fidelity (alignment with stakeholder requirements and operational intent), behavioral fidelity (accuracy of simulation, response, and prediction under defined conditions), data integrity (provenance, timeliness, quality, and synchronization with physical assets), and contextual fidelity (representation of environmental, temporal, and organizational constraints). The standard prescribes a staged validation process—encompassing planning, specification of validation objectives and success criteria, execution of tests/scenarios, evidence collection, and formal sign-off—and emphasizes iterative validation throughout the digital twin’s lifecycle, not just at deployment. For mining applications, this includes validating twin capabilities for real-time equipment monitoring, predictive maintenance, safety scenario simulation, and production optimization against actual mine site KPIs, sensor networks, and geological models. Crucially, ISO 23247-2 requires documented traceability between validation artifacts (e.g., test cases, logs, metrics) and the original system requirements, enabling regulatory compliance, certification readiness, and continuous improvement.
