What is post-market monitoring under the EU AI Act?
Post-market monitoring is the continuous surveillance of high-risk AI systems after they are placed on the market or put into service. Under Article 72 of the EU AI Act (Regulation (EU) 2024/1689), providers of high-risk AI systems must establish and maintain a post-market monitoring system to collect and analyze data on the performance of their AI systems throughout their lifecycle.
Post-market monitoring serves multiple compliance purposes:
- Risk Mitigation: Identify emerging risks and performance degradation before they cause harm
- Incident Detection: Detect serious incidents that require immediate notification to authorities
- Continuous Improvement: Gather data to improve AI system performance and safety
- Regulatory Compliance: Demonstrate ongoing compliance with EU AI Act requirements

What are the Article 72 requirements for post-market monitoring?
Article 72 of the EU AI Act establishes mandatory post-market monitoring obligations for providers of high-risk AI systems. The regulation requires providers to actively and systematically collect, document, and analyze relevant data on the performance of their AI systems.
What is a post-market monitoring plan?
Article 72(2) requires providers to establish and keep up-to-date a post-market monitoring plan. This plan must include:
- Methods and procedures for collecting performance data
- Data sources and collection frequency
- Analysis methodologies and metrics
- Thresholds for triggering corrective actions
- Procedures for incident detection and reporting
When must corrective actions be taken?
Article 72(3) requires providers to take corrective actions when post-market monitoring reveals that a high-risk AI system presents a risk to health, safety, or fundamental rights. Corrective actions may include:
- Updating the AI system to address identified risks
- Providing additional instructions to users
- Temporarily suspending or withdrawing the AI system from the market
- Notifying relevant authorities and users
How to report serious incidents under Article 73?
Article 73 of the EU AI Act requires providers to report serious incidents to the relevant market surveillance authority without undue delay, and in any event, no later than 15 days after becoming aware of the incident.
What constitutes a serious incident?
A serious incident is defined as any incident that directly or indirectly leads to:
- Death or serious injury to a person
- Significant property damage
- Breach of obligations under Union law intended to protect fundamental rights

How to build an automated post-market monitoring system?
Implementing automated post-market monitoring requires integrating data collection, analysis, and alerting capabilities into your AI system infrastructure. The following components are essential for compliance with Article 72.
What are the key components of a monitoring system?
- Data Collection Layer: Automated collection of performance metrics, error logs, and user feedback
- Analysis Engine: Real-time analysis of collected data to detect anomalies and performance degradation
- Alerting System: Automated notifications when thresholds are exceeded or incidents are detected
- Incident Management: Workflow for incident reporting and corrective action tracking
- Reporting Dashboard: Visualization of monitoring data and compliance metrics
How to integrate monitoring with existing AI systems?
Post-market monitoring must be integrated into your AI system architecture. Consider the following integration points:
- API endpoints for real-time performance data collection
- Log aggregation systems for error and anomaly detection
- User feedback mechanisms for collecting incident reports
- Database systems for storing monitoring data and compliance records
What data must be collected for post-market monitoring?
Article 72 requires providers to collect relevant data on AI system performance. The following data categories are essential for compliance:
How to implement post-market monitoring in 5 steps?
Implementing post-market monitoring for EU AI Act compliance requires a systematic approach. Follow these five steps to establish a compliant monitoring system.
Step 1: How to develop a post-market monitoring plan?
Create a comprehensive post-market monitoring plan that documents:
- Monitoring objectives and scope
- Data collection methods and sources
- Analysis procedures and metrics
- Thresholds for triggering alerts and corrective actions
- Incident reporting procedures
- Roles and responsibilities
Step 2: How to set up data collection infrastructure?
Implement automated data collection systems that capture:
- Performance metrics from AI system operations
- Error logs and system events
- User feedback and incident reports
- Bias and fairness indicators
- Security and cybersecurity events
Step 3: How to implement analysis and alerting?
Deploy analysis systems that:
- Detect performance degradation and anomalies
- Identify potential serious incidents
- Trigger automated alerts when thresholds are exceeded
- Generate compliance reports for regulatory authorities
Step 4: How to establish incident reporting procedures?
Create procedures for reporting serious incidents that include:
- Incident detection and classification
- Internal escalation workflows
- Template for incident reports to authorities
- Timeline management to meet 15-day reporting deadline
- Follow-up reporting procedures
Step 5: How to maintain compliance records?
Establish record-keeping systems that maintain:
- Monitoring data and analysis results
- Incident reports and corrective actions
- Updates to the post-market monitoring plan
- Audit trails of monitoring activities
What are the best practices for post-market monitoring?
Effective post-market monitoring requires following established best practices for data collection, analysis, and incident management.
How to ensure continuous monitoring coverage?
Implement monitoring that covers all aspects of AI system performance:
- Monitor all deployment environments (production, staging, development)
- Track performance across different user groups and demographics
- Collect data from multiple sources (system logs, user feedback, external monitoring)
- Maintain monitoring during system updates and changes
How to set appropriate monitoring thresholds?
Establish thresholds that balance early detection with false positive reduction:
- Base thresholds on baseline performance metrics
- Consider statistical significance when detecting anomalies
- Adjust thresholds based on monitoring experience and feedback
- Document threshold rationale for regulatory review
How to automate incident detection and reporting?
Automate incident detection and reporting to ensure timely compliance:
- Use automated systems to detect serious incidents
- Generate incident reports automatically when incidents are detected
- Implement workflows that ensure 15-day reporting deadline is met
- Maintain audit trails of all incident reporting activities
