Terms related to data · 3.2.9
input data
data an AI system uses to work out a predicted output or an inference
What this term settles
The term looks ordinary until two teams use it differently. The entry removes that room by naming the thing, its inputs and its limits in one sentence.
Who it binds
A definition binds nobody on its own. It binds the reader who adopts input data in a policy, a contract, a data schema or an assurance argument.
What to do in your practice
Take the firm own definition of input data, put it beside this one and mark the differences. Each difference is either a deliberate local choice or an inconsistency to fix.
Evidence an auditor or regulator asks for
- A controlled vocabulary entry for input data with the citation 3.2.9, an owner and a review date.An auditor can check that the term is controlled rather than assumed.
- A data inventory field that records the entry for each dataset used in training or operation.Shows input data in use in the artefact the firm relies on, not only in a glossary.
- A data quality record with the check, the date and the person who signed it off.The data inventory is organised by system rather than by dataset, so the same data is described twice with different labels.
Common gaps this page catches
- input data is used in the data record behind every AI system without a written definition, so two teams can mean different things.
- The term appears in a template with no citation, so the reader cannot tell which sense was intended.
What to prepare before the amendment lands
Put input data on the agenda of the next AI governance meeting with two questions: where is it used, and what would show it is used correctly? Record the answers as actions.
How to test it here
Take one live artefact rather than a template, find the sentence or field where input data 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 input data at the claim level "definition" and stops where the public record stops.
Common questions
- What does input data mean in ISO 22989?
- data an AI system uses to work out a predicted output or an inference
- What evidence should we keep for 3.2.9?
- A controlled vocabulary entry for input data with the citation 3.2.9, an owner and a review date. A data inventory field that records the entry for each dataset used in training or operation.
- Is input data a requirement?
- No: input data is a definition or clause of a terminology standard, and it becomes binding only when a firm writes it into a policy, a contract or a procedure, or when another standard incorporates it.
