What is the Bowtie Model?

The bowtie model, aka bowtie method or bowtie analysis, helps visually represent risk illustrating the relationship between potential causes of an undesired event, the event itself, and its possible consequences.

The model gets its name from its distinctive shape, which resembles a bowtie when fully constructed.

The key components of a bowtie model include:

1. Hazard: The central element that has the potential to cause harm.
2. Top Event: The point at which control over the hazard is lost.
3. Threats: Potential causes that could lead to the top event.
4. Consequences: Potential outcomes if the top event occurs.
5. Barriers: Preventive and mitigative measures to control risks.

Historical Context and Evolution

The bowtie method of risk assessment has its roots in the 1970s when it was first conceptualized by the Imperial Chemical Industries in the UK.

However, it gained significant traction in the 1990s when Royal Dutch Shell adopted and refined the method for use in its operations.

Over the years, the bowtie model risk management approach has evolved from a simple diagram to a sophisticated risk analysis tool.

With the advent of bowtie model SaaS platforms, organizations can now create, analyze, and manage complex risk scenarios more efficiently than ever before.

Why It’s Called a “Bowtie”

The name “bowtie” comes from the shape of the diagram when fully constructed.

The left side of the bowtie represents the potential causes or threats, while the right side shows the potential consequences.

The knot in the middle represents the top event – the point at which control is lost. This visual representation makes it easy for stakeholders to understand and communicate complex risk scenarios.

The importance of the bowtie method lies in its ability to provide a clear, comprehensive view of risk scenarios.

By visually mapping out threats, consequences, and barriers, the bowtie model helps organizations identify potential weaknesses in their risk management strategies and implement more effective controls.

For example, in a workplace safety scenario, a simple bowtie model example might look like this:

• Hazard: Working at heights
• Top Event: Fall from height
• Threats: Slippery surfaces, inadequate training, faulty equipment
• Consequences: Injury, fatality, property damage, legal liabilities
• Barriers: Safety harnesses, proper training, equipment maintenance

By using the bowtie method risk management approach, organizations can proactively identify and address potential risks before they escalate into major incidents.

This makes the bowtie model an invaluable tool for risk assessment across various industries, from oil and gas to aviation and healthcare.

The Anatomy of a Bowtie Diagram

Understanding the structure of a bowtie diagram is crucial for effectively implementing the bowtie method of risk assessment.

Take a look at how these elements work together to create a powerful risk management tool.

Hazard and Top Event

At the center of every bowtie diagram is the hazard and the top event.

• Hazard: This is the potential source of harm or damage. In a bowtie model example, a hazard could be “flammable materials in a chemical plant.”
• Top Event: This represents the point at which control over the hazard is lost. Continuing our example, the top event might be “uncontrolled release of flammable material.”

The hazard and top event form the core of the bowtie model risk assessment, serving as the focal point from which all other elements branch out.

Threats and Preventive Barriers

On the left side of the bowtie diagram, we find threats and preventive barriers:

• Threats: These are the potential causes that could lead to the top event. For our chemical plant scenario, threats might include “equipment failure,” “human error,” or “natural disasters.”
• Preventive Barriers: These are the controls put in place to prevent threats from causing the top event. Examples include “regular equipment maintenance,” “staff training programs,” and “robust emergency response plans.”

The bowtie method risk management approach emphasizes the importance of identifying all potential threats and implementing effective preventive barriers to minimize risk.

Consequences and Mitigative Barriers

On the right side of the bowtie diagram, we see consequences and mitigative barriers:

• Consequences: These are the potential outcomes if the top event occurs. In our example, consequences could include “fire,” “explosion,” or “environmental contamination.”
• Mitigative Barriers: These are measures designed to reduce the severity of consequences if the top event does occur. Examples might include “fire suppression systems,” “evacuation procedures,” or “containment measures.”

By visualizing both preventive and mitigative barriers, the bowtie model provides a comprehensive view of an organization’s risk management strategy.

Escalation Factors and Controls

Lastly, the bowtie diagram includes escalation factors and their associated controls:

• Escalation Factors: These are conditions that could cause a barrier to fail or be ineffective. For instance, “lack of maintenance” could be an escalation factor for the “regular equipment maintenance” barrier.
• Controls: These are measures put in place to manage escalation factors. Continuing our example, a control might be “implementing a rigorous maintenance schedule and audit process.”

The inclusion of escalation factors and controls in the bowtie model risk management approach ensures a more robust and realistic assessment of potential risks and the effectiveness of barriers.

Understanding the anatomy of a bowtie diagram is crucial for leveraging the full power of the bowtie method.

These SaaS bowtie model platforms often provide additional features like real-time updates, collaboration tools, and advanced analytics to enhance the risk assessment process.

Step-by-Step Guide to Creating a Bowtie Diagram

Mastering the bowtie method of risk assessment is crucial for effective risk management.

This step-by-step guide will walk you through the process of creating a bowtie diagram, helping you implement the bowtie model risk management approach in your organization.

Identifying the Hazard and Top Event

The first step in the bowtie method is identifying the hazard and top event:

1. Define the hazard: Identify a potential source of harm or damage in your operation.
2. Determine the top event: Pinpoint the moment when control over the hazard is lost.

Example: In a chemical plant, the hazard might be “toxic chemicals,” and the top event could be “uncontrolled release of toxic chemicals.”

Brainstorming Threats and Consequences

Next, identify potential threats and consequences:

1. List threats: Brainstorm all possible causes that could lead to the top event.
2. Identify consequences: Consider all potential outcomes if the top event occurs.

Use a diverse team to ensure a comprehensive analysis.

This step is crucial in the bowtie model risk assessment process as it helps identify all potential risk scenarios.

Determining Preventive and Mitigative Barriers

Now, focus on barriers:

1. Preventive barriers: Identify measures to prevent threats from causing the top event.
2. Mitigative barriers: Determine actions to reduce the severity of consequences.

Ensure each barrier is specific, measurable, and realistic.

This step highlights the importance of the bowtie method in developing a robust risk management strategy.

Considering Escalation Factors

Identify potential weaknesses in your barriers:

1. List escalation factors: Determine conditions that could cause barriers to fail.
2. Develop controls: Create measures to manage these escalation factors.

This step enhances the effectiveness of your bowtie model risk management approach by addressing potential vulnerabilities.

Finalizing and Reviewing the Diagram

Complete your bowtie diagram:

1. Arrange elements: Place all components in the appropriate sections of the diagram.
