Learn Bowtie Analysis

Bowtie analysis is a simple and effective tool for communicating risk assessment results to employees at all levels.  The subsequent diagrams clearly display the links between the potential causes, preventative and mitigative controls and consequences of a catastrophic event. This type of analysis allows for:

• Determining whether hazards are sufficiently controlled
• Easy identification of the hazards driving the risk for action prioritisation
• The whole risk assessment to be summarised on a single page
• Clearer communication of risk assessment results and risk concepts leading to heightened awareness of major risks.

Bowtie diagrams may also be integrated with semi-quantitative analysis techniques such as Layers of Protection Analysis (LOPA) depending on the level of complexity required.  The general structure of a bowtie diagram is represented in the diagram below.
