Value streams of the enterprise can be described in the form of functional processes. For example, when an enterprise operates out of numerous geographical locations, organization of business process operations can vary significantly between regions.

It is therefore useful to have a summary view, independent of organizational structure, to represent steps in the value stream connected to enterprise business and common to all organizational variants.

A functional representation of the value stream also facilitates improvement in enterprise operation.

Indeed, when the operation of process is represented, this enables local optimization of each process.

This structure however remains partitioned by existing organizational structures. More significant changes require a broader view of the value stream, independent of organization. This global view is represented by the value stream diagram.
