Systems and methods for determining the impact of an asset on an enterprise architecture using a data model are disclosed. These systems and methods may determine the impact of a particular asset on the enterprise architecture represented by the data model, where determination of the impact of any particular asset takes into account not only assets that depend directly on that particular asset, but assets that depend indirectly on that asset as well. Using the data model of the enterprise architecture, dependency chains for one or more components of the data model can be discovered and a dependency map created. Using impact ratings associated with relationships between components in the dependency chains of a particular component, the impact of that particular component both on another individual component, and aggregately on an environment, can be determined. These systems and methods may also allow the determination of the risk of a particular component.
