In a policy handling system performing automatic execution, management, and control of a system, a policy retrieving section (102) retrieves a policy associated with a triggering condition, and notifies a policy-execution-pattern analyzing section (105) of the retrieved policy. A policy-operation-log retrieving section (106) refers to a policy-operation-log storage section (107) to acquire the number of triggering times of the retrieved policy in a predetermined history acquisition period. The policy-execution-pattern analyzing section (105) compares the number of triggering times of the retrieved policy against a predetermined threshold and causes an abnormality notifying section (108) to issue abnormality information when the number of triggering times exceeds the threshold.
