The Cause Road Map© has many conceptual roots including the Institute of Nuclear Power Operation’s Anatomy of an Event Model, Kaoru Ishikawa’s Cause & Effect (Fishbone) Diagrams and Dr. James Reason’s “Swiss Cheese” model.
The Cause Road Map© is a series of hierarchical logic steps (displayed in the below seven different “Maps”) that are designed to aid investigators in identifying the underlying causes for both equipment failures and human performance errors.
Each of the “Maps” also provide a tie to associated Cause Codes. These codes, in turn, provide an intuitive framework (each code is a mnemonic for the causal factor it represents) for discussion, trend analysis and information retrieval.
