Abstract:
A computer-implemented system for determining, by logical progression through multiple analysis levels, a human factor that represents a root cause of a particular incident, the system beginning at a broad analysis level and progressing through more narrow analysis levels to a root cause level, where each analysis level includes multiple causal factor categories, and where a causal factor category branches into causal factor subcategories that reside on a more narrow analysis level, the system comprising:(a) an information input device for inputting incident information relating to the particular incident and for converting the incident information into a system-compatible format; (b) a memory device for storing a causal information database that provides a relationship between the multiple analysis levels and causal factor categories and between causal factor categories and root causes, and that relates root causes to corrective actions that may be implemented to prevent future occurrences of the incidents, the memory device for storing the causal information database that includes; a difficulties level, a basic cause level, a near root cause level, and the root cause level, where the causal factor categories on the difficulties level branch into causal factor subcategories that reside in the basic cause level, where the causal factor categories on the basic cause level branch into causal factor subcategories that reside in the near root cause level, and where the causal factor categories on the near root cause level branch into causal factor subcategories that reside in the root cause level, the difficulties level having a human performance difficulty category, an equipment difficulty category, and a natural phenomenon/sabotage category, and the basic cause level having a procedures category, a training category, a quality control category, a communications category, a management system category, a human engineering category, and an immediate supervision category, each comprising causal factor subcategories of the human performance difficulty category, (c) a processor connected to the information input device and to the memory device, the processor for accessing the causal information database and determining a human factor that represents a root cause of the particular incident by logically progressing through the multiple analysis levels based upon the incident information from the information input device, the processor logically progressing through the multiple analysis levels by selecting, based upon the incident information, an appropriate causal factor category at each analysis level, the processor for accessing the causal information database and determining at least one corrective action that may be implemented to prevent future occurrences of the particular incident based on the root cause of the particular incident; and (d) a display device connected to the processor for displaying a graphic representation of the multiple analysis levels, where the graphic representation indicates the causal factor categories selected by the processor in determining the root cause of the particular incident, and for displaying the at least one corrective action that may be implemented to prevent future occurrences of the particular incident.
