Abstract: A method, an electronic device and computer readable medium is provided. The method includes information associated with operational changes by personnel that operate an industrial plant. The method also includes identifying episodes of the operational changes, wherein each episode includes a triggering event and operational changes. The method also includes generating a causal pairing matrix that categorizes the identified episodes into a plurality of groupings, based on the triggering event of each of the at least two episodes being similar. The method further includes analyzing the at least two episodes to identify one of the at least two episodes as a bench mark episode, within each group. The method also includes comparing each of the at least two episodes to the identified bench mark episode to rank the at least two episodes, within each of the groups. The method further includes generating a report for the plurality of groupings.
