How should a hub-and-spoke Digital Twin be governed to balance global consistency with local AI relevance?

In a hub-and-spoke setup, the hub stores a centralized, authoritative Business Brain and a global Q&A network, while each spoke carries local signals, media and a limited set of locale-specific Q&As that point back to the hub’s facts and proofs. Governance should use a formal Change Control process with defined roles, versioning, approvals, and an auditable Change Log. Local updates must be validated before propagating to AI-facing outputs to prevent drift in core facts. This structure preserves global consistency and auditability while enabling local relevance when customers ask location-specific questions.
