Control Change Cause Analysis (2002)
Brief description
3CA is a method of root cause analysis, designed to assist the
investigation of accidents of any type. It assists the
investigator to identify significant episodes
within an accident and to structure inquiries into the reasons
underlying them.
Development
3CA has its origins in a co-operative project run by
Humber Chemical Focus and the UK Health & Safety Executive
in 2000. 3CA was produced in response to a
need for a root cause tool that was quick to learn,
systematic, transparent and which produces
results that are easy to communicate.
