Post-market monitoring system

The set of activities through which a provider keeps following how its AI system behaves in practice after launch, so it can intervene in time. Conformity is a starting point, not an end point.

The official source remains authoritative. This is general information about obligations and not legal advice. See this object on the map

What this object links to

Every relation appears below as a path: from the source with its locator, through the conditions and exceptions of the object carrying the relation, to the consequence. A locator belongs to a statement in the data and not to a relation, so the source is the source anchor of the carrying object.

What this object states

Official fact

Attributable to a named primary source, with a locator. Where they differ, the official source prevails.

Article 3(25) defines this as all activities carried out by providers of AI systems to collect and review experience gained from the use of AI systems they place on the market or put into service, for the purpose of identifying any need to immediately apply necessary corrective or preventive actions.

Our interpretation

Our own reading. It can change without the law changing, and it is not the position of a supervisory authority.

This is where organisations consistently slip: they treat the conformity assessment as the finish line and organise nothing afterwards. The definition instead establishes a continuous obligation covering the entire lifetime of the system, elaborated in Article 72 into a mandatory monitoring plan. It is not about waiting passively for a complaint, but about actively collecting and reviewing. For high-risk systems this bites from 2 December 2027 (Annex III) and 2 August 2028 (Annex I), but the monitoring system must be designed in from the start, since otherwise you have no historical data to demonstrate drift or degradation.

Recommended step

A practical step we consider appropriate. Not an obligation following from the Regulation.

Record per AI system which signals you collect (complaints, support tickets, anomalous outcomes, performance measurements over time), who reviews them, at what frequency, and which threshold triggers a corrective action or a serious incident report. Keep the review records with date and model version, so you can later show that you did not start measuring only after an incident.
