Systems and methods for information technology system change planning are described. In an information technology system change planning method in accordance with an embodiment, a change request is received on a network server (310). Domain objects and dependencies among domain objects are identified to form a model (320). Refinable tasks, atomic tasks, and state transitions are selected from a knowledge base based on the change request and the model (330), including dependencies. A workflow is created for implementing the change request using a processor (340). The workflow can be based on the model and may include a combination of selected refinable tasks, atomic tasks, and state transitions used to implement the change request.
