Method, server, and computer product are provided to implement change management across domains. Memory is included for storing a program. A processor is functionally coupled to the memory and is responsive to computer-executable instructions contained in the program. The processor is operative to announce planned changes for a configuration item to interested outside domains, and the configuration item is in an inside domain. Open subscription is provided to the interested outside domains such that the interested outside domains can subscribe to the subscription as participants. A change instance is created or the configuration item in the inside domain. Change progress of the change instance is reported for the configuration item to the participants of the interested outside domains. State progress notifications are distributed to the participants of the change. The change instance is executed to make planned changes to the configuration item.
