An objective of the present invention is to minimize fault detection delay in an invariant analysis for a plurality of systems to be analyzed. An operation administration system (1) comprises a correlation model storage unit (212), an analysis sequence storage unit (412), an analysis unit (300), and a sequence control unit (400). The correlation model storage unit (212) stores a correlation model (222) which represents a correlation between a plurality of types of performance values for each of a plurality of systems. The analysis sequence storage unit (412) stores a correlation destruction detection sequence for the plurality of systems. In each of a plurality of periods, the analysis unit (300) uses the performance values which are inputted for the period to detect whether correlation destruction of the correlations which are contained in the correlation models (222) of each of the plurality of systems has occurred, in accordance with the detection sequence. The sequence control unit (400) updates the detection sequence in each of the plurality of periods.
