Consequences in a bowtie: why describe them as events rather than damage?

One of the guidelines we use when creating bowties is to describe the consequences as events, rather than damage. However, we see that many bowtie-creators struggle with the description of a consequence. In this blog, we explain how to describe consequences in the bowtie. Describing your consequences A common approach is that the bowtie-creator defines a total of four consequences for the top event: Injury/fatalities, asset damage, environmental damage, and reputation damage. Most likely, all hazards involve the above four in some way and one could simply copy and paste [...]

Big Data in your Bowtie

Guest blog by Coen van Gulijk, professor of railway safety and risk at the University of Huddersfield. Bowties are an effective visual representation of the risk space that you want to control. Bowties connect hazards, threats, consequences and most importantly controls in a clear interface. With the new BowTieServer, several functions can be added to bowties that provide you with relevant information about the quality and status of barriers: AuditXP, IncidentXP and Investigator 3 are examples of this. These products pave the way towards extensive data-integration for safety management systems: Big [...]

5 reasons why analysing barrier failures is better than 5-why

Guest blog by Alex de Ruijter (Risk management psychologist) from Slice I hope you'll forgive me, but I don't really like 5-why. It's a decent methodology (especially if you don't do incident analysis often), but in my opinion there are better options. Instead, we can use barrier-based incident analysis methods like Tripod Beta, Barrier Failure Analysis or BSCAT. I'll use Barrier Failure Analysis in this post. If you don't know what that is, take a look at the picture in this post. Why is this better? Well, here are 5 [...]

Dynamic Barrier Monitoring in BowTieXP with Systems & Parts

Many companies want to extend the BowTieXP functionality to integrate with their (computerized) Maintenance Management System, so they can display the (real-time) availability of their hardware barriers. Technical barriers usually consist of systems that are made up of multiple parts. By displaying the online/offline status of hardware parts and (sub)systems, decisions can be made in the context of live risk scenarios (bowties). This can help answer questions like “Can we still safely run operation X when hardware parts 1, 12 and 15 are offline?” This blog introduces the Systems & [...]
