Bow Tie Diagram

The Bow Tie Diagram, named for its distinctive shape, provides a one-page visual roadmap that outlines the causes of high-risk situations, the controls in place to prevent them, the potential impacts, and the preparedness measures to minimize those impacts. 

Developed by Public Health Foundation (PHF) Senior Quality Advisor Jack W. Moran and performance improvement expert Sonja Armbruster, this tool helps uncover causal relationships in high-risk, high-impact scenarios that could cause major disruptions to an organization.
