Latent error detection: A golden two hours for detection.

Area of Science:

• Human Factors and Ergonomics
• Systems Engineering
• Cognitive Psychology

Background:

• Undetected errors in safety-critical systems create latent conditions that can lead to future failures.
• Latent Error Detection (LED) is a process observed in naval air engineers using diaries to record errors.
• Understanding sociotechnical factors is crucial for effective error management.

Purpose of the Study:

• To explore sociotechnical factors influencing Latent Error Detection (LED).
• To identify optimal conditions for detecting latent errors post-task completion.
• To propose interventions for mitigating latent errors in safety-critical contexts.

Main Methods:

• A systems view and multi-process theories were employed.
• Naval air engineers used diaries to record Latent Error Detection (LED) events.
• Analysis focused on environmental and temporal factors influencing LED.

Main Results:

• Perception of environmental cues aids successful LED.
• Reviewing past tasks within two hours of an error, in a similar sociotechnical environment, is most effective for LED.
• Ergonomic interventions show potential for mitigating latent errors, especially in habitual tasks.

Conclusions:

• Safety-critical organizations should implement LED techniques engaging system-wide cues.
• Engineering resilience through LED is more effective than relying solely on human performance.
• Proactive detection and mitigation of latent errors are key to enhancing overall system safety.
