IPICA_Lite—Improvements to root cause analysis

Reliability Engineering and System Safety, 2014, vol. 131, issue C, 1-13

Abstract: A few modifications can significantly improve root cause analysis using predefined trees. These modifications are based on adopting four ideas: (1) Causes represent deficiencies in processes. (2) Processes connected to causes are grouped into a hierarchy. Superior processes shape the subordinate ones. (3) The same safety management system can be applied to all processes in the hierarchy. (4) The structure described in the CCPS Guidelines for Risk Based Process Safety represents a universally applicable safety management system. Simultaneously, it can be transformed into a universal RBPS Root Cause Map.
