Abstract: A change management system issues work tickets that list particular procedures for performing an action, for example, in a data center. If these procedures are not followed precisely, then an outage may occur. Advantageously, the change management system may be communicatively coupled to an infrastructure management system for verifying that the procedures were performed properly. For any work ticket that involves support devices (e.g., power supplies or cooling mechanisms) that are monitored by the infrastructure management system, the change management system may send a request to the infrastructure management system to verify that these support devices are in the correct mode or state. If not, the change management system may refuse to close the ticket and instruct a technician to change the support device to the proper condition. This may prevent outages that occur from a technician failing to follow the procedures detailed by the change management system.
