Tripod Incident Causation Model

Event Failed barrier Precondition Immediate cause Underlying cause An

rganisation

Underlying causes Preconditions Immediate causes

Error / violation promoting conditions That influences the person Causes To take action or inaction That causes barriers to fail That result in Accidents, incidents and business upsets

What could we measure

Barrier reliability Classification of Human Error Completion of safety critical activities Management activities and behaviours

SLIDE 11

Stichting Tripod Foundation

How to decide what to measure

Ask the workforce What is the time and effort to collect the data What conversation do you want to create Use the Tripod Accident Causation and Bow tie models to generate alternatives

SLIDE 12

Stichting Tripod Foundation

Conclusions

Celebrate that injury rates are no longer an

effective measure of performance

Think of the type of conversation you are

trying to create

Ask the workforce
Use our understanding of accident causation to

generate new measures to create positive conversations
