Bow-Tie Analysis
Reference model
The Bow-Tie diagram illustrates risks, their causes, consequences, and controls clearly.
About this model
A method that combines fault tree analysis and event tree analysis to provide a comprehensive view of risks and their management.
Originator not stated.
How to read it
- Read the left side for causes and controls to prevent the risk.
- Read the right side for consequences and controls to mitigate the impact.
What this does
Visualizes the relationship between potential risks, their causes, consequences, and controls, helping teams manage risk effectively.
When to use it
Use it when you need to understand and communicate the risk landscape for a specific event or hazard.
Not when: Do not use it when risks are too complex to simplify into a single diagram or when detailed quantitative analysis is required.
What happens next
Consider a risk register to track identified risks and controls over time.
