Operational feedback
Also known as: Field feedback
In systems engineering, operational feedback is information from operation, service, incidents and users that may trigger updates to risks, requirements, controls or documentation. It closes the loop between the field and engineering.

- Functional safety
- Technical documentation
In one sentence
Operational feedback from service, incidents and users is what keeps risk assessments, requirements and manuals aligned with reality.
Example
Service reports show that operators of a packaging machine often open a side panel to clear jams; this operational feedback leads to a new risk assessment entry, an interlock and a revised jam-clearing instruction.
How it applies
- Machine safety: Incidents, near misses and observed workarounds are evidence of reasonably foreseeable misuse. Feed them back into the risk assessment.
- Evidence: Record each feedback item, its assessment and the decision taken. Field data can also confirm or refute operating assumptions and reliability estimates.
- Technical documentation: Questions from users and service technicians show where instructions fail. Track them as documentation defects.
- AI: For AI-based functions, operational feedback is part of post-deployment monitoring and can reveal drift.
Operational feedback vs. field data
Field data are measured values from operation. Operational feedback is broader: it includes reports, complaints, incidents and observations, and it is aimed at triggering a decision.
