Value Streams Inventory and Attributes

Enterprise Architecture depends on this inventory as the view of how the enterprise delivers value. An enterprise can know its capabilities, its applications, and its processes in complete detail and still be unable to answer the question its stakeholders care about most: how is value actually delivered, end to end, and where is its delivery slow, constrained, or failing? The Value Streams Inventory is the artifact that answers that question. It provides the end-to-end view that no capability-level, application-level, or process-level inventory can provide on its own.

The Value Streams Inventory is the natural companion to the Capabilities Inventory. The Capabilities Inventory records what the enterprise is able to do; the Value Streams Inventory records how those abilities are orchestrated into flows that deliver value. Used together, the two inventories let an enterprise trace a line from a stakeholder outcome, back through the value stream that delivers it, to the Capabilities the value stream depends on, and onward to the applications, processes, and organizational units that realize those Capabilities. That traceable line is what makes capability and technology investment defensible: it connects the investment to the flow of value it is meant to improve.

The Enterprise Model depends on this inventory as the layer that represents value delivery. Value streams sit at the point where strategy meets execution: they are concrete enough to be measured, improved, and owned, and broad enough to mean something to an executive stakeholder. Value-stream-anchored queries are how the Enterprise Model answers cross-cutting questions — which value streams are most constrained, which depend on a fragile capability or a single vendor, which carry the heaviest regulatory load — that no single other inventory can answer alone.
