A failure prediction device generates a failure predictor pattern in accordance with previous cases of failure that has occurred in a first system, the failure predictor pattern being used to detect a predictor of failure in the first system configuration. When a system configuration is changed from the first system configuration to a second system configuration, the failure prediction device calculates the difference information that indicates the difference between the system configurations by using the number of changes that is the accumulated number of times that a change of the configuration item which is included in a system is executed. The failure prediction device determines, in accordance with the calculated difference information, whether the failure predictor pattern is applicable to the detection of a predictor of failure in the second system configuration.
