7.7.2 Contribution of business functions to value
Value chain diagramsc provide a high-level orientation view of an enterprise and how it interacts with
the outside world. They do not provide an exhaustive or formal view of the enterprise, but rather
concentrate on the impact of certain orientations and on the relative importance of certain decisions.
The aim is to quickly align decision-maker views on priorities and the relative importance of components. All participants must quickly understand the organizational and functional context of an architectural engagement.
