AI Model Register Template
An institution that cannot list its AI systems cannot govern them. The register is the base record that every other governance activity refers to: tiering, approval, review, and incident response all read from it and write back to it.
One table, one owner, updated at every gate. Fields below are the minimum that survives an audit.
| Field | Purpose |
|---|---|
| System ID | Stable identifier used across all other systems |
| Business owner | Named individual who accepts the output, not a team |
| Technical owner | Named individual accountable for operation |
| Purpose statement | One sentence on the decision this system informs or makes |
| Consequence tier | 1 to 4, assigned by the tiering criteria below |
| Build or buy | Internal, vendor, or vendor component embedded in a wider product |
| Model and version | Including vendor model identifiers where applicable |
| Data sources | Systems of origin, plus lawful basis where personal data applies |
| Human role | Decides, reviews, or is informed |
| Stopping condition | Observable trigger for withdrawal |
| Authorised to stop | Named individual and their delegate |
| Approval date and approver | |
| Next review date | Mandatory field, no null values permitted |
| Incidents to date | Count and link to records |
How to use it
- Create one table with one owner. Distributed registers held per department stop reconciling within a quarter.
- Populate business owner and technical owner with named individuals, never a team or a role. Accountability that is not attached to a person is not accountability.
- Update the register at every gate rather than on a review cycle, so the record and reality do not diverge between reviews.
- Treat next review date as mandatory with no null values permitted. A null there is how systems quietly leave supervision.
