Bowtie is one of many barrier risk models available to
assist the identification and management of risk and it is this particular model we have found (and
are still finding) useful.
These pages explain:
This information is based on how the CAA has gone about producing their own bowties with
assistance from Across Safety and CGE.
There are different ways to go about a bowtie but we recommend trying different processes to see
what works for you. We hope you can see the benefits in our approach which has been based on the
bowtie software BowTie XP. However the terminology for the bowtie elements can be applied
when using other methods to create a model such as on Visio, post-it notes or in Excel
The assessment of the bowtie elements which helps in identifying the safety and risk priorities
can also be applied without using the specific software – it is all part of the risk conversation
to appreciate where those improvement areas are in the aviation system.
If you are part of the UK Aviation industry, you are able to access some starter bowties
focusing on the Significant Seven and the relevant risks. These bowties have been jointly
constructed by industry experts and colleagues from the CAA.
