Who Is Responsible for AI Governance?

Assign one accountable role for each material decision while identifying the functions that supply facts, operate procedures, challenge conclusions, or receive notification. Test whether the accountable person controls the required budget, access, staffing, and authority to stop or change the use case. The scope should be explicit enough that two reviewers can reach a comparable view using the same facts, while still recording uncertainty that requires further investigation.

Decision records should show accountable approval and meaningful specialist input rather than a list of copied stakeholders. The record should show who made the decision, what information was considered, which control or threshold applied, when the decision was reviewed, and how exceptions were resolved. That chain is more useful than a policy statement because it can be traced to a system, owner, and operating event.

Map ownership for discovery, inventory maintenance, intended use, data, development or procurement, validation, deployment, monitoring, incidents, changes, and retirement. Pay particular attention to vendor features and embedded AI, where commercial, technical, and business responsibilities often fall between teams. The scope should be explicit enough that two reviewers can reach a comparable view using the same facts, while still recording uncertainty that requires further investigation.

The inventory and workflow should expose any lifecycle stage without an owner, backup, required competence, or escalation route. The record should show who made the decision, what information was considered, which control or threshold applied, when the decision was reviewed, and how exceptions were resolved. That chain is more useful than a policy statement because it can be traced to a system, owner, and operating event.

Define when risk, legal, privacy, security, compliance, or internal audit challenge is mandatory and preserve their ability to raise issues independently. Avoid assigning control operation and independent assurance to the same person where the risk and organizational scale require separation. The scope should be explicit enough that two reviewers can reach a comparable view using the same facts, while still recording uncertainty that requires further investigation.

Retained challenges, responses, overrides, escalations, and assurance findings show whether governance tolerates scrutiny in practice. The record should show who made the decision, what information was considered, which control or threshold applied, when the decision was reviewed, and how exceptions were resolved. That chain is more useful than a policy statement because it can be traced to a system, owner, and operating event.
