Human Factors Analysis and Classification System (HFACS) — Pathway Mapper

HFACS-Mapper is a powerful tool designed to facilitate structured and consistent analysis of human performance using the HFACS framework. It enables investigators, safety professionals, and analysts to systematically identify contributing factors, apply a standardized taxonomy, and enhance the quality and comparability of investigations across teams and industries. The tool is freely accessible, supporting data-driven learning, cross-sector collaboration, and the continuous improvement of safety performance.

Start your analysis:

• Start by selecting a Human Factor from the diagram and describe what happened.
• Your notes will appear on the map, adding context and bringing the story to life.

Build your diagram from the bottom up:

• Select related factors as you move upward through the HFACS diagram.
• Continue until all relevant contributing factors are covered.

Visualise causal relationships:

• Paths will automatically appear between selected factors to indicate potential causal links.
• You can remove any path by simply clicking on it.

Stay safe and enjoy exploring the system!
