Human-out-of-the-loop
Also known as: Fully automated decision-making, HOOTL
German: Vollständig automatisierte Entscheidung
In industrial AI and automation, human-out-of-the-loop is an operating mode in which the system makes and executes decisions without human involvement in individual decisions; people only define the system's goals and limits and review its performance afterwards.

In one sentence
Human-out-of-the-loop means a system decides and acts without human involvement in individual decisions, within predefined limits.
Example
An AI model sorts recyclable materials on a conveyor at high speed; no person reviews individual decisions, but quality samples are checked every shift.
How it applies
- Engineering: Fully automated operation requires well-defined limits, robust fallbacks and monitoring, because nobody catches individual errors in real time.
- Compliance: For high-risk AI systems under the EU AI Act, human oversight measures are required, so a fully automated design needs careful assessment. Other laws may also restrict automated decisions affecting people.
- Documentation: Document the limits within which the system acts, the monitoring in place, how performance is reviewed and how the automated mode can be stopped.
Human-out-of-the-loop vs. conventional automation
Conventional automation also acts without human decisions, but its logic is fixed and verifiable. With AI, behavior is learned from data and can change with data, which calls for Model monitoring and periodic revalidation.
