The purpose of a root cause analysis is often not to find the {only,all} root cause, but to prevent the incident at hand from repeating by removing something which is necessary. Event Y happens if and only if factor X. Factor X is what the RCA is supposed to find to prevent event Y. There may be many factors which satisfy this equation which means there may be multiple RCAs which are correct and functional in achieving our goal, to prevent event Y.
