A What is BowTieXP?
What is BowTiexP?
BowTieXP is the most used risk assessment software that is 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.understandable picture. The diagram is shaped like a bowtie, creating a
clear differentiation between the proactive and reactive side of risk
management. In BowTieXP, the bowtie diagram provides you with 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,
Structure knowledge
Structure knowledge
The bowtie method structures major hazards of your organization and gives
you a clear overview of how your hazards are controlled. The barriers in the
bowtie diagram show what controls you have in place to prevent, mitigate
or eliminate major consequences from happening. Making people
responsible for barriers makes transparent what everybody is supposed to
do to operate safely. When operational staff is involved in the development
of a bowtie, accurate daily operation information is included and this way
staff will take ownership of the bowtiesSystem (SMS) on the diagram. Each activity can be traced back to the barrier
it is supporting. The SMS exists primarily in identifying safety critical
activities, undertaken to assure the on-going integrity of risk barriers.
Displaying all data on the bowtie enables everyone to see the complete risk
context, together with the activities they are responsible for.

Analyze and assess
Once you have built a bowtie diagram, you can analyze and assess the
safety barriers that you've implemented. Various categories can be linked to
these barriers to identify amongst others the effectiveness, type or
accountability of each barrier. Analyze the barrier effectiveness to get
instant visual insight into the strength of your barriers. In BowTieXP barrier
effectiveness is often shown with a traffic light color code, but this is
customizable to your needs.organization and decrease the likelihood of common mode failure.
Accountability can be linked to barriers via customizable job titles. This
helps to get insight into which people are responsible for the performance
of safety barriers. It makes transparent what everybody is supposed to do
to operate safely and increases ownership of barrier performance.

In BowTieXP you can easily generate risk matrices to assess if you've
adequately controlled all your risks in a visual way. The risk matrices can
easily be customized to company standards. Inherent and residual risk
assessments allow demonstration of improvement in risk levels.
Easy to read & communicate
Easy to read & communicate
Bowtie diagrams ensure easy risk communication by making the risk visual
and understandable on the right abstraction level. To distribute the bowtie
diagrams, organizations are using posters, pocketbooks and leaflets for
example to highlight key risk control issues. Web-based bowtie diagrams
are also increasingly a part of online training and information systems. This
makes sure that risk communication is fully integrated into the
organization.‘A bowtie diagram that only shows the information relevant for the HSE manager.
Besides being easy to understand, bowties also provide an overview and
insight in risk analysis and assessment. This is due to the fact that bowtie
diagrams reduce complexity to a manageable size without losing context
and focus on the critical elements, The bowtie diagram can be
communicated to every department within your organization, using several
filter options in the software. Filters allow you to decide which information
you want to display on your diagram, without deleting any information. For
example, you can filter the diagram on a specific job title to show the
relevant information for this particular accountable person,
Bowtie diagrams can also be used to demonstrate that risks are being
controlled, This provides management with the assurance that risks are
being managed properly. This was the primary driver for the
implementation of the approach within Shell in the mid-1990's. Because of
the visual power of the bowtie diagram, many regulators in various
industries recommend bowtie diagrams to be used in safety studies or
safety cases,
User-friendly diagrams
User-friendly diagrams
Building a diagram in BowTieXP is easy and user-friendly. When hovering
over elements, plus buttons will appear which allows you to add new
bowtie elements. These plus buttons make the software more intuitive and
much faster to use. It is possible to adjust your bowtie any time andand dropping’ functionality.
