SCAT™ is Systematic Cause Analysis Technique,a well-established root cause analysis approachwhich incorporates the DNV loss causation model.The model is a sequence of dominos establishingthe hierarchy of accident progression from theimmediate cause back to fundamental root causesand system failures.
In short - BSCAT is the barrier based extension toDNV’s SCAT method.
The SCAT model (Systematic Cause AnalysisTechnique) was developed to help incidentinvestigators apply the DNV loss causation modelto actual events. This is done by means of the SCATchart. The chart was created to build–out an eventusing standardized event descriptions that can tthe whole range of incidents and near misses. Dueto using a standardized list, incident analyses aresuitable to aggregation, leading to more insightinto the weak areas of your safety managementsystem.
A barrier-based accident investigation still appliesthe SCAT model but now it is applied to each barrierseparately, not to the incident as a whole.
The BSCAT chart is the latest update of the SCATapproach. It includes all the historical occupationalsafety topics and underlying causes, but has addedprocess risks to the list (e.g. res and explosions)and in general more suitable to barrier analysis.
The BSCAT software allows you to reuse and linkexisting risk assessment information (bowties) anddo full integration of incident analysis and risk
analysis.
If applicable bowtie diagrams are available for useduring your investigation, you can bring events andbarriers from the bowtie directly into your BSCATanalysis. This results in a better t between incidentand risk assessment analysis, which in turn allows
you to improve the risk assessment.
The mismatch between risk analysis and incidentanalysis referred to above, is usually in theperspective/abstraction level of the dened barriers– barriers in incident analyses tend to be describedtoo specically, and there less ‘mappable’ onto thebarriers in your risk assessments.
By reusing the bowtie risk analysis and/or describingthe barriers in your incident analyses at the sameabstraction level, this gap is bridged and morevalue is extracted from your incident analyses.
This entire process allows you to gauge barriereffectiveness and availability based on real-worldinformation extracted from the incident analyses.
The BSCAT™ method refers to a methodthat links modern risk–based safetymanagement approaches to systematicroot cause incident investigation. The“B” refers to barrier–based as each barrier
identied in bowtie risk assessments istested for why it failed.
