|Value chain diagrams|
A value chain diagram provides a high-level orientation view of an enterprise and how it interacts with the outside world. In contrast to the more formal functional decomposition diagram developed within Phase B (Business Architecture), the value chain diagram focuses on presentational impact. The purpose of this diagram is to quickly on-board and align stakeholders for a particular change initiative, so that all participants understand the high-level functional and organizational context of the architecture engagement. A usual practice consists in showing a simplified business process diagram, and for each task defining its value factors and changes needed.
