1. A method, comprising: registering a plurality of task implementation tools to interface with a change management tool, the change management tool configured to associate a unique change identifier (“unique Change ID”) with a change request specifying a change to an information technology infrastructure's configuration, to configure a plurality of tasks to implement the change, associate each of the plurality of tasks with an unique individual task identifier (“unique Task ID”), and send a plurality of task instructions to the plurality of task implementation tools for performing the plurality of tasks, each task instruction being directed to a targeted task implementation tool for performing a particular task of the plurality of tasks to implement the change to the information technology infrastructure's configuration specified by the change request, each task instruction including task-related information for the targeted implementation tool to perform the particular task, the unique Change ID associated with the change request and the unique Task ID associated with the particular task; and wherein registering the plurality of task implementation tools to interface with the change management tool includes registering each of the plurality of task implementation tools to accept the task instruction for the particular task directed to it from the change management tool, to know what to do with the task instruction and to know how to respond to the task instruction.
