A device management apparatus includes a communication processing circuit and a service support processing circuit. The communication processing circuit receives device state information transmitted from a first operator. The device state information indicates device state information of the electronic device. The first operator performs solution work to a failure of the electronic device. The service support processing circuit determines a category into which the device state information is classified from the received device state information. The service support processing unit searches a database for a second operator or a candidate for the second operator. The second operator has solved a failure belonging to the determined category. The database stores operator information including a solution result of a failure of each operator. The service support processing unit decides the searched second operator or the searched candidate for the second operator to assist or complement the solution work by the first operator.
