Abstract

A value model that can be used to value an enterprise function is provided. The value model includes one or more levels of enterprise function nodes that are related to each other and/or a bottom level of driver metric nodes, such as driver metric nodes in a value driver graph. The modification to one or more enterprise function nodes can be received and a value impact of the modification can be determined based on the modification and the relationships in the value model. In this manner, the value model provides an effective manner for determining a value impact on a particular value measurement that a specific enterprise function, such as an information technology solution/service, provides/is expected to provide.
