The present invention provides a technique of assisting in forming plans of measures for management reforms, which are specific to an individual enterprise, and a technique of verifying formed plans of measures. In the present invention, a general business-operation-index vector f that includes a plurality of indexes indicating the condition of business management; a general plan-of-measures vector x including a plurality of plans of measures which are information about how to deal with the condition indicated by each index included in the general business-operation-index vector f; and a problem-index vector f′, are used. On the basis of these, a problem-index—plan-of-measures matrix Mm′ is produced which defines correlation between the problem-index vector f′ and a plan-of-measures vector x′ (Step 3221). A potential plan-of-measures vector x′ is selected from the general plan-of-measures vector x by extracting the plans of measures in the column of the matrix Mm′ (Step 3222). A gross-investment (necessary to execute plans of measures) matrix Mi is produced (Step 8223). A relational expression between the problem indexes and the plane-of-measures (f′=Mm′·x′) are produced Step 8224).
