In the context of TOGAF and Business Architecture, the diagram depicts the relationship between a Value Stream, Value Stage, and Value.
Value Stream: Represents the end-to-end set of activities that create and deliver value to a stakeholder.
Value Stage: A distinct step or phase within the Value Stream.
Value: The benefit delivered to the stakeholder.
The relationship "X" indicates that a Value Stream is composed of multiple Value Stages.
Think of it like a journey (Value Stream) with multiple stops along the way (Value Stages). Each stage contributes to the overall value delivered at the end of the journey.
