Terms related to AI · 3.1.23
model
a representation, whether physical, mathematical or logical, of an entity, a system, a phenomenon, a process or data
What this term settles
A governance lead borrows this meaning whenever model appears in a risk assessment or an assurance argument. The borrowing is safe only if the artefact behind it matches the description.
Who it binds
A definition binds nobody on its own, so the force of model comes only from the reader who adopts it in a policy, a contract, a data schema or an assurance argument.
What to do in your practice
Add model to the vocabulary register and to the onboarding pack. A term that is only in a PDF is not controlled; it is controlled when a new joiner can find it and a reviewer can test it.
Evidence an auditor or regulator asks for
- A controlled vocabulary entry for model with the citation 3.1.23, an owner and a review date.An auditor can check that model is controlled rather than assumed.
- An AI system inventory field that records the entry for each system, with its owner. The row names model.Shows model in use in the artefact the firm relies on, not only in a glossary.
- A policy or procedure sentence that uses the entry in this sense. The record carries the model entry and its date.The policy borrows the word but not the boundary, so a supplier system and an in-house model are treated as the same kind of thing. The gap is tested against model.
Common gaps this page catches
- model is used in the AI vocabulary a policy reaches for first without a written definition, so two teams can mean different things.
- The entry for model exists in a glossary but not in the system record, so the two disagree at the point of use.
What to prepare before the amendment lands
Brief the owners who use model most often, then ask each to return one artefact that shows the entry in use. File the artefacts against the register row.
How to test it here
Take one live artefact rather than a template, find the sentence or field where model is used, and put this page beside it. Record the answer, the artefact and the date, because that record is the evidence and a glossary entry on its own is only an intention.
What this page does not claim
The page does not reproduce the standard, certify the firm or predict the wording the amendment will use; it states model at the claim level "definition" and stops where the public record stops.
