Short answer
When investigating failures or near-misses, move beyond surface-level technical faults to deeply analyze the human element – how people interacted with the system, their cognitive load, and the environmental pressures they faced.

Integrating human factors principles into incident investigation processes significantly enhances the identification of root causes and the development of effective preventative measures. This human factors research insight is drawn from a 2002 study published in Lincoln (University of Nebraska). Using Case study analysis and program evaluation, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When investigating failures or near-misses, move beyond surface-level technical faults to deeply analyze the human element – how people interacted with the system, their cognitive load, and the environmental pressures they faced.

Key Findings
- 01A significant majority of incidents (80%+) involve human error.
- 02Existing incident investigation programs often fail to adequately identify and address human errors.
- 03Incorporating human factors leads to better identification of safety problems and more appropriate corrective actions.
Application
Design takeaway
When investigating failures or near-misses, move beyond surface-level technical faults to deeply analyze the human element – how people interacted with the system, their cognitive load, and the environmental pressures they faced.
How to apply
When designing any system or process where human interaction is critical, build in mechanisms for post-incident analysis that explicitly consider human factors, such as usability, cognitive load, and decision-making biases.
Project actions
- 01When analyzing a design failure, consider the user's actions and mental state.
- 02Think about how the design might have contributed to a user error.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Highlights the critical role of human factors in safety.
- +Provides a framework for improving investigation processes.
Limitations
It can be challenging to accurately assess a user's cognitive state or decision-making process after an incident has occurred.
Reliability & validity
The study's validity is supported by its focus on a well-documented problem (human error in incidents) and its analysis of organizational practices. Reliability could be enhanced by quantitative data on the outcomes of investigations with and without human factors integration.
Think critically
To what extent can a design truly eliminate human error, or should the focus be on designing for error tolerance and recovery?
Design Principles
"Investigate incidents through a human-centered lens to uncover systemic vulnerabilities."
Traditional incident investigations often focus on immediate technical failures, overlooking the complex interplay of human cognition, perception, and decision-making. By systematically analyzing human factors, design practitioners can uncover deeper systemic issues that contribute to errors, leading to more robust and sustainable safety solutions.
What This Means for Your Design
When things go wrong, it's often because people made mistakes. This research shows that if you look closely at *why* people made those mistakes (like being tired, stressed, or not understanding something), you can fix the problem much better than just fixing the broken machine.
How to use in your project
- 1.Use human factors principles to justify design choices aimed at preventing user error.
- 2.In your analysis of existing products, identify potential human factors issues that your design will address.
