Regulatory and consumer-trust failures arise because systems cannot demonstrate, in real time, that they operate within acceptable constraints for external stakeholders.

This talk introduces a model-based approach to designing governable systems, in which engineers systematize independently verifiable and substantiated claims about their own behavior.

Using a domain-specific application of Model-Based Systems Engineering (MBSE) called Combined Assurance Blueprinting (Creative Commons), we show how governance concepts drawn from ISO 31000, the Institute of Internal Auditors (IIA), and the International Assurance and Audit Standards Board (IAASB) standards can be represented alongside system architecture, operational processes, and verification mechanisms within a unified system model. From this model, systems can generate continuous proof of correct operation, enabling first, second, and third-party assurance without the need for periodic retrospective audits.

The outcome is systems that continuously demonstrate compliance with operational and regulatory constraints while enabling engineers, operators, and external stakeholders to reason about system behavior with shared models.
