BowTieXP is a software tool which is used for risk assessment based on the bowtie method. It enables you to easily create bowtie diagrams to assess risk. BowTieXP is unique in its ability to visualize complex risks in a way that is understandable, yet also allows for detailed risk-based improvement plans.
A bowtie diagram visualizes the risk you are dealing with in one understandable picture. The diagram is shaped like a bow tie, creating a clear differentiation between the proactive and reactive side of risk management. In BowTieXP, the bowtie diagram provides you an overview of multiple plausible incident scenarios and shows what barriers you have in place to control these scenarios.
BowTieXP software is developed with the end-user in mind, making it one of the most user-friendly risk assessment tools. It is easy to create a diagram in BowTieXP, but the software also enables you to maintain the diagram so it will always represent the current status of your safety barriers.

What BowTieXP Offers?

New Risk Assessment

  • BowTieXP makes the risk assessment process highly interactive. Through the BowTieXP Workshop
    Process, more relevant risk information is captured and stored in the BowTie diagram
  • No matter at what level of detail you will be analying the risk, BowTieXP keeps track of the big picture for you.
New Risk Management
  • BowTieXP has a laser focus on helping you to identify what needs to be done to deal effectively with the risk.
  • BowTieXP provides the ideal visualisation for thinking through what happens when multiple risk scenarios occur
    simultaneously. Thus enables BowTieXP to be particularly useful for major accident prevention.
New Risk Communication
  • BowtieXP diagrams is designed from the ground up to be easily communicable and provides you with many option
    to tailor the diagram for your audience(s).
  • BowTieXP diagrams is designed to effectively communicate the risk context of the work environment, targeting
    the single greatest cause of mistake-based incidents.

Layers of Protection Analysis (LOPA)


LOPA is a semi-quantitative risk analysis in which the frequency of a negative event is calculated according to the risk reduction by the Independent Protection Layers (IPLs). In bowtie-based LOPA, you calculate the frequency of a consequence, given the threats and IPLs in play.

The LOPA functionality allows you to fill in the initial frequencies of the threats and the Probability of Failure on Demand (PFD) for the barriers. You can also add target frequencies for the consequences and the top event. The software automatically calculates the relevant numbers, like the consequence frequency, and displays them on the bowtie diagram if desired.

What is IncidentXP?


IncidentXP is a incident analysis software product which allows you to use the most popular and globally used incident analysis methods. IncidentXP uses the same software framework as BowTieXP, which makes it possible to link incident analysis results back to the proactive risk assessment diagram. However, IncidentXP can also be used as full-fledged stand-alone incident analysis tool.


4 Analysis Methods


Four of the most innovative barrier based incident analysis methods were selected for IncidentXP. All can be used as full fledged stand-alone tools, or in combination with BowTieXP.

  • BSCAT™
  • Tripod Beta
  • Barrier Failure Analysis
  • Root Cause Analysis

Link with BowTieXP


Besides being a tool to analyze incidents, IncidentXP also allows you to use BowTieXP risk assessments to check if the investigation covered everything that was identified in the BowTie diagram.

After this has been done, the final results will link back to the BowTie risk assessment to aggregate and detect trends across incidents. This allows an organization to maximize learning from incidents and ensures the BowTies are continuously updated and improved. With this, IncidentXP allows organizations to take the next step in learning from incidents.


What is AuditXP?

AuditXP is our audit and compliance software, employing the same software framework as BowTieXP. The tool is developed to close the “Plan-Do-Check” circle (Deming circle). After defining the barriers in your safety management system (the plan stage) and implementing them (the do stage), AuditXP is used to check and monitor the quality and effectiveness of the barriers.




Monitor the performance of Safety Barriers.

  • Use BowTies to create Risk based Audits

Monitoring Barrier performance

  • A remaining challenge in Risk Management is monitoring the performance of Safety Barriers in the organisation once they're identified.

  • AuditXP allows questions to be attached to the technical and behavioral barriers that have a direct impact on safety, as well as the underlying management systems that implement and maintain Barriers.

Export Excel questionnaires

  • It's easy to export an Excel sheet with a list of questions, send the file to multiple persons, and import the answers back into BowTieXP. No complicated IT implementation required.

Surveys, Mini-audits, Checklists

  • Although it was designed with auditing in mind, BowTieXP Audits can also be used in different ways. For instance when creating a survey to distribute to a larger audience.

  • Instead of waiting a long time until the next big audit arrives, perhaps a mini-audit with 5 to 10 random questions is a good way to ensure more continuous monitoring.

  • Another creative application could be to use it for checklists. Ensuring all relevant barriers are in place before starting a non-routine operation.

Create overview or see the details

  • You can see the BowTie overview, or zoom into a single comment. It depends on what you want to achieve.

High quality reports

  • Audit results can be exported into several beautiful Word reports. These are standardised formats ranging from high level to detailed reports.

Visual Audits

  • Instead of hiding audit results in lists with answers, we visualize results on the BowTie itself. This makes potential problems instantly recognizable.
