Bow Tie Analysis is a risk assessment technique used to clearly visualize how risks arise and what consequences they may lead to. Its strength lies in presenting complex risk scenarios in a simple, cause-and-effect structure that supports better decision-making.

Named after its distinctive shape, the Bow Tie method places root causes on the left, the risk event at the center, and consequences on the right. This layout allows teams to see how threats, events, and impacts are connected, making risks easier to understand and manage.

How to Implement Bow Tie Analysis in Five Steps

Identify the Event

Define the hazard and clearly state the risk event that sits at the center of the diagram.

Identify Left Nodes (Causes)

Trace backward to identify root causes or threats that could trigger the event.

Identify Right Nodes (Consequences)

Determine potential impacts and consequences, including possible damages or disruptions.

Define Preventive Measures

Add control measures on the left side to reduce the likelihood of threats leading to the event.

Define Mitigation Measures

Place recovery or mitigation controls on the right side to minimize damage if the event occurs.

Bow Tie Analysis provides a clear, structured way to understand risks, strengthen controls, and improve overall risk management effectiveness.
