Editing hazard details ensures that your risk data remains accurate and up to date. This is an important step in maintaining an effective BowTie analysis.

Overview

In BowTiePro, threats and consequences define how a hazard can lead to an event and what outcomes may occur. You can quickly add multiple threats or consequences along with controls using the Quick Add feature.

Accessing the Quick Add Screen

1. Open a Hazard

2. Click “Quick Add”

Adding Threats

By default, the Threats tab is selected.

3. Enter Threat Description

4. Add Controls for the Threat

5. Select Control Type

8. Enter Consequence Description

9. Add Controls for Consequences

Saving the Entries

The Quick Add feature allows you to efficiently create multiple threats and consequences along with their controls. This helps build a complete BowTie model quickly and accurately.

Overview

Controls are critical elements in BowTiePro that help prevent threats from causing a top event or reduce the impact of consequences. Controls are linked directly to threats and consequences and can be added during the risk modeling process.

How Controls Are Structured

In BowTiePro:

Adding Controls

1. Open a Hazard

2. Click “Quick Add”

3. Add Controls While Creating Threats

Under the Threats tab:

4. Add Controls for Consequences

Viewing Controls

After saving:

Controls are linked within these items and contribute to the BowTie structure.

Managing Controls

To update controls:

Controls are essential for managing risk in BowTiePro. By linking controls to threats and consequences, you can build a strong and effective risk model that helps prevent incidents and reduce impact.

Overview

Escalation factors are conditions that can reduce the effectiveness of controls in a BowTie model. Managing escalation factors is important to ensure that controls continue to perform as intended and risks remain properly managed.

What Are Escalation Factors?

An escalation factor is something that can:

Example:

Why Escalation Factors Matter

Even if controls are defined:

Escalation factors help identify:

How Escalation Factors Are Used in BowTiePro

In BowTiePro:

Managing Escalation Factors

To manage escalation factors:

1. Identify Potential Weaknesses

2. Add Escalation Factors

3. Apply Additional Controls (if required)

4. Review and Update Regularly

Escalation factors help ensure that controls remain reliable under real-world conditions. By identifying and managing these factors, you can strengthen your overall risk management strategy in BowTiePro.
