AI Governance Maturity Model: How to Assess Enterprise Readiness

Describe each level through actions that can be observed: who decides, what workflow operates, which population is covered, and how performance is challenged. Separate design maturity from operating maturity so a documented process cannot receive full credit before teams use it consistently. 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.

Use anchored examples for each rating and record contrary evidence, scope exclusions, and confidence in the assessment. 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.

Score visibility, ownership, risk, controls, evidence, monitoring, and reporting as distinct capabilities because weaknesses rarely advance at the same pace. Sample business units and systems rather than relying only on central policy owners, and reconcile material differences between stated and local practice. 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.

Retain the sampled population, interview notes, artifacts reviewed, rating rationale, and gaps that prevented a stronger conclusion. 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.

Prioritize the maturity gaps that constrain important decisions or leave material AI use outside governance, rather than treating every score difference as equally urgent. Define a target capability, owner, dependency, measure, and proof of completion for each selected improvement. 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.

Track accepted gaps and deferred actions alongside funded remediation so leadership can see residual exposure and delivery risk. 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.
