An object of the present invention is to enable a user to grasp the operation of the autonomous system for executing a countermeasure corresponding to a state of a system to be managed and to enable the user to check if a problem has been solved after the countermeasure taken against the problem of the system to be managed is performed by the user or by the autonomous system when the countermeasure performed by the autonomous system has failed or when the user wants to confirm the solution by the countermeasure performed by the autonomous system. An autonomous collaborative work operation control section 6 indistinctively records the content of a countermeasure corresponding to a manual operation and the content of a countermeasure taken not by the manual operation but by an autonomous operation in an autonomous collaborative work log storage section 5. The autonomous collaborative work operation control section 6 and autonomous collaborative work screen drawing section 7 display the fault of a system to be managed the solution of which has not been confirmed to allow the user to select an unresolved fault. Further, the autonomous collaborative work operation control section 6 and autonomous collaborative work screen drawing section 7 displays a screen for determining the countermeasure content for solving the fault. The autonomous collaborative work operation control section 6 executes the countermeasure according to the operation performed by the user and adds a log.
