Bowtie Diagram: Easy Risk Management Tool For Your Business

Bowtie Diagram: Easy Risk Management Tool For Your Business

Risk management is a crucial aspect of any organization's operations. It's essential to control business threats that could harm your company badly. This tactic provides the tools to identify dangers and create countermeasures.

There are multiple tools you can use to represent and evaluate threats. One of the most effective ones is the Bowtie Diagram, which also considers causes and consequences from both a Fault Tree and an Event Tree analysis.

This article will consider the main concepts of Risk Management and the tools you can use to monitor potential threats that could harm your business.

What is Risk Management?

Risk management is a structured process where you can measure the uncertainty and risk of a thread.

This analysis does exhaustive research to evaluate risks and establish a strategy for risk controls.

You are identifying, assessing, and controlling potential risks in your organization – for example, financial, legal, and strategic issues that could become escalation factors and real headaches for your business.

Risk management will help you return processes to their logical flow. Traditional bowtie diagrams – and other similar graphics – will help you develop preventive controls and consider all the consequences.

Why Should You Make a Risk Analysis?

As a business owner or any other business role, you can use risk analysis for multiple objectives, especially if you combine it with a bow tie analysis.

Some of the situations when you can apply a risk analysis with the bowtie method are:

  • When developing a project to anticipate issues or reinforce existing control.
  • When deciding to move ahead with a plan.
  • When improving adverse event prevention systems.
  • While preparing against circumstances you can’t control, such as technology failure, theft, staff sickness, etc.
  • While developing new management strategies and other changes in your company, such as digital healthcare research or starting an annual scientific meeting in your IT department.

When you develop a risk analysis, you create barriers against all those issues.

What Is a Bowtie Diagram

A bowtie diagram is a visual tool used in risk management to analyze potential risks and identify appropriate control measures.

It’s called a “bowtie” because it typically has that shape, with a central "knot" representing the potential risk and two "wings" representing the risk consequences and causes. Bow-tie diagrams can be used to identify the most effective control measures to prevent the threat from occurring or mitigating its potential impact.

The diagram is easy to understand and follows a particular time flow from left to right.

An easy illustration of what the bow-tie diagram tries to express can be:


“This happened [event] because of [reason]. Resulting in this [effect].”


It’s an easy formula that works to understand the bowtie diagram concept. Still, its application is made by management roles for risk controls. As such, you shouldn’t apply it to any problem, only those representing an actual situation of human error.


Essentially, the Bowtie diagram:

  • It’s a simple, straightforward, and concise way to determine the event occurring.
  • It provides possible causal factors about an event linked to a situation that could harm your business.
  • It helps with risk assessment.
  • It’s a supporting diagram that can be used with other risk management techniques.

Analyses Available To Measure Risks

You can use a few analyses to measure critical events and learn the possibility of them happening.


Event Tree Analysis


The event tree analysis technique is a method that comes straight from the decision tree analysis. This accident-cognition procedure considers adverse events and outcomes in chronological order.

This methodology uses an event tree approach to explain the relation between future events and their motives for happening. 

Event tree analysis is a quantitative risk evaluation based on events and the chance of finding solutions.

Fault Tree Analysis


The fault tree analysis identifies the cause of an event. It’s a framework that works as a guide to finding information about a plan of action. As a systematic analysis, the fault tree approach is used in tandem, so you can see grouped factors that will help you identify threats.

Fault tree analysis is a systematic approach to identifying an event's primary cause using a fault tree diagram. It can also be viewed as a framework that systematically guides you to transform available information into a concrete plan of action.

Bowtie Analysis


The bowtie diagram combines the two previous analyses. As such, this method is a qualitative cause-consequence analysis of an event.

You have a combined Fault Tree with the Event Tree aligned together to form this new technique.

The approach of this analysis is often drawn from brainstorming sessions, so you can expect to discuss a lot with decision-making roles to obtain fruitful information to create an excellent control strategy.

Benefits Of Using Bowtie Diagrams

A generalized Bowtie diagram is easy to understand and can manage escalation factors. So, applying the Bow-tie method will grant you these benefits to your project:

1. You can visualize how a critical event should evolve.

2. Brings information about specific barriers of the risks, threats, consequences, and critical events.

3. Creates scenarios following a logical cause-and-effect model.

4. Works as an excellent mapping tool to identify scenario weaknesses to improve decision-making.


As you can see, using the conceptual Bowtie diagram gives you plenty of benefits when applying it to your business.

Cons Of The Bowtie Diagram

Just as with any other accident-probability analysis, they have flaws.

As such, here are some of the cons of using the Bowtie diagram as a management tool:

1. Bowtie diagrams require deep knowledge.

2. It may take time to develop a successful bowtie program.

3. Some barriers could ignore potential hazards, necessarily leading to an unstable situation.

4. If done improperly, there could be misleading threats and escalation factors.


The Bowtie diagram and its analysis shouldn’t be taken for granted, as it may seem easy to understand but could potentially bring more troubles than solutions.

How To Create a Bow-tie Model

Now, if you’re still interested in developing a diagram using conventional Bowtie terminology, this is what you need to do:


Identify a Proper Threat


Before developing a bowtie diagram, you must consider that every Bowtie Diagram requires a threat to functioning. The idea is that you identify something that could cause an effect in your business that you want to prevent—For example, a downloaded unauthorized software that could bring ransomware. As a result, the virus could encrypt the server’s data and provoke significant losses.

So, create a Bowtie that starts in the middle, expressing the event you want to analyze. To do this, ensure everyone involved or affected by the potential incident is aware of the event.


Include Potential Causes


A Bowtie Diagram has two sides, one for causes and the other for effects. As such, the Bowtie diagram represents a comprehensive analysis of the potential risk that could affect your business, which is why sources and effects are included.

You must add on the left-hand side all the potential threats that could jump-start an event. You don’t need to rank them. Just type them down as they come.


Add The Possible Consequences


Now on the right-hand side, add all the effects from those causes. This is essential to see how a critical event may evolve if you don’t apply escalation controls.

Create a Logical Flow


Now that you added all that the Bowtie Diagram represents, you must check if there’s a logical flow of events.

This means you must start from the left side and say: If [cause] happens, then [event] will occur as a result [effect].

If everything is related and flows accordingly, you have a correct Bowtie Diagram.


Develop Measures For Control And Risk Mitigation


Now that you’re sure that your Bowtie is correct, you must start including measures that prevent the event from happening.

You should do this on both sides – cause and effect – to have a quality improvement in your project. Existing controls aren’t enough and tend to be generic. This is why having specific procedures against the analyzed situation is essential.

For example, imagine this hypothetical scenario:

If a key employee misses their work, the company could suffer from a personal shortage. As a result, the business won’t be able to satisfy daily demands and goals.

One countermeasure could be doing a medication safety risk analysis and giving extended global medical training to your staff in case something happens inside the office’s walls.


Create Support Activities To Boost Control Measures


Besides the main control measures, it’s also recommended to include safety protocols to improve the measured results.

Some of those tasks could be:

  • A dynamic risk analysis.
  • A hazard analysis course for specific staff.
  • Disaster response plans.

The idea is that you can ensure the potential threat doesn’t happen. The ultimate outcomes should be preventing all risk sources while empowering safety measures in your business.


List Safety Critical Equipment


Last but not least, you need to identify all the equipment necessary to control potential hazards progressing. Since the main use of the Bowtie Diagram is for risk assessment, these items would be safety-critical equipment. 

You should include information like:

  • Times you’ll use them.
  • Functionality.
  • Performance.
  • Availability.

It’s a simple process that you can include on any risk assessment diagram you do – such as the 

Swiss Cheese Diagram.

The Best Program To Create Qualitative and Quantitative Bowtie Diagrams

To create any type of diagram – like anesthesia Bowtie diagrams relating to medical learning – you need a solid productivity software.

Microsoft Excel is one of the best productivity tools in the market so far for immediate management of your projects. This software doesn’t come alone. When you purchase a Microsoft Office license, you also get other programs like Word, Publisher, PowerPoint, etc.

You can combine them and improve your experience by creating conclusion bowtie diagrams.

RoyalCDKeys allows you to get the whole software suite for barely $10. This way, you can obtain a Microsoft Office 2021 license that will help you activate the programs and start using them to create the ultimate Bowtie Diagram.

Bowtie Diagram - Summary

Risk management is a process that involves identifying, assessing, and controlling potential risks that could impact an organization. 

One tool you can use in risk management is a bowtie diagram, which visually represents the potential risk at the center, with the causes and consequences on either side. 

They are usually prepared to identify effective control measures to prevent or mitigate the impact of risks. 

Other techniques for analyzing risks include event tree analysis, which considers the chronological order of events and outcomes, and fault tree analysis, which identifies the root causes of an event. 

These analyses can help businesses make informed decisions and develop strategies for risk management.
