Bowtie Risk Analysis Method

The Bowtie Risk Analysis Method is a cause-and-effect analysis method that provides a simple, qualitative approach to help fully understand the multidimensional characteristics of a risk event. A bowtie diagram illustrates three elements: hazards (specified risks), top events (specified event/moment when control is lost), and consequences. Bowtie diagrams help distill complex risk scenarios into simple visualizations of risk that would otherwise be more difficult to explain. This method applies treatment actions to each dimension of a risk event, and is a useful way of visualizing and communicating the effectiveness of the implemented risk treatment methods.
