TRIPOD bèta is available in the public domain.

Origanally initiated by Shell through research of the Leiden and Manchester Universities (James Reason), the TRIPOD incident analysis approach is made available in the public domain. So everyone can use it without any restrictions. This site is set up to help the (potential) users to reach the added value of the method: better learning from incidents by identifying and removing the underlying factors in the organisation. This will no doubt lead to a higher safety level.

The TRIPOD incident analysis method (also called TRIPOD bèta) starts with the identification of failing safety provisions (barriers). The structure that is used is completely in line withe the Safety Model 'Bowtie'. See e.g. here for an application for offshore safety and the Swiss Cheese models from Reason.  In Tripod, the failing  barriers are analysed with respect to the direct causes of failures, the Preconditions which encouraged the direct causes and finally the Latent failures in the organisation which produced the Preconditions. The term "Latent Failures'is from Reason.  The theory being that if we will succeed in removing the Latent Failures, the Precondtions will disappear and the barrier will stay fit for purpose, which means that the incident rate will go down considerably.
