 <!--summary-end-->
 
-The [Use Case Tree](../concept/use-case-tree.md) is a foundational mechanism to create an ecosystem of 
-reusable components for the EKG.
+## Objective
+
+**Reuse Enablement** is the discipline of designing, packaging, and
+governing every knowledge asset — use case, ontology, data product, or
+workflow — so that it can be safely reused across teams, domains, and
+generations of technology.
+
+It is the foundation of the Enterprise Knowledge Graph (EKG): without
+reuse, there is no composability, no scalability, and no sustainable
+intelligence.
+The EKGF Method defines reuse not as a technical afterthought but as a
+*core architectural principle* — embedded in the way we plan, build,
+and run every enterprise capability.
+
+## Why It Matters
+
+Enterprises waste enormous effort solving the same problems repeatedly —
+integrating the same data, remodelling the same business rules,
+recreating the same workflows.
+
+Most of this duplication stems from one cause: **knowledge is not shared
+as reusable components**.
+
+When knowledge lives in silos — spreadsheets, slide decks, bespoke
+systems — every project begins from zero.
+By contrast, a reuse-enabled organisation captures its work as
+semantically defined, governed components that can be discovered and
+recomposed anywhere across the enterprise.
+
+The result:
+
+- Drastically reduced duplication and cost
+- Higher quality and consistency through shared models
+- Faster delivery and innovation
+- Stronger alignment across business and technology
+
+## Beyond Data: The Real Meaning of Reuse
+
+Most "semantic technology" initiatives of the past two decades have been
+driven from the **data perspective** — led by integration specialists and
+ontology engineers.
+They delivered powerful data harmonisation but rarely transformed how
+the enterprise actually *works*.
+
+That is where the **Enterprise Knowledge Graph (EKG)** and **Use Case
+Tree (UCT)** shift the paradigm.
+They treat **reuse not as a data exercise**, but as the foundation for
+*application composition*.
+In the EKGF Method, reuse is not limited to triples or ontologies — it
+extends to **behaviour**, expressed as *Stories* and *Workflows*.
+
+Just as **object-oriented programming** in the 1980s combined data and
+methods into a reusable "object,"
+the **Use Case Tree (UCT)** combines data, logic, and process into a
+reusable **semantic package**:
+a use case that contains its meaning (ontology), its data products, and
+its behaviour (stories, workflows, outcomes).
+
+This is the crucial difference:
+
+!!! tip "The EKGF Method paradigm shift"
+
+    Instead of describing data that *others must code against*, the EKGF
+    Method captures *the behaviour itself* — executable, governed, and
+    reusable across domains — without necessarily writing code at all.

+```
+
+In this sense, a **Use Case** in the EKG is just as real and reusable as
+a software package in the JavaScript or Python ecosystems.
+Each can be discovered, installed, versioned, extended, and composed —
+but the EKG package operates at the **semantic and business level**,
+spanning data, logic, and meaning.
+
+That's why **reuse** is not a side effect of the EKG.
+It's the *reason the EKG exists.*
+
+## The Role of the Use Case Tree (UCT)
+
+In the EKGF Method, the **Use Case Tree (UCT)** is the mechanism that
+makes reuse practical and governed.
+
+Each node in the UCT acts as a *semantic package* — a defined,
+versioned, and discoverable unit of business capability.
+Within a UCT package, teams can register:
+
+- **Ontologies and shapes** defining meaning and validation
+- **Stories** (tool functions or APIs) that implement reusable logic
+- **Data products** describing and delivering reusable datasets
+- **Workflows and policies** orchestrating repeatable patterns
+
+Every successful technology ecosystem has a way to **share reusable
+components** — the JavaScript world has [*npm*](https://www.npmjs.com)
+with over 3.5 million packages, the Python world has
+[*PyPI*](https://pypi.org) with over 600,000 packages, and so on — each
+enabling developers to build upon a vast ecosystem of reusable
+components.
+The **Use Case Tree (UCT)** plays the same role for the **Enterprise
+Knowledge Graph (EKG)**: it is the *semantic package manager* that makes
+every business capability, dataset, and workflow discoverable, versioned,
+and ready for reuse across the organisation.
+
+## Reuse Enablement vs. Composable Business
+
+### Two sides of the same semantic coin
+
+While *Reuse Enablement* and *Composable Business* share the same
+foundation, they operate at different levels of abstraction.
+The table below summarises their relationship within the EKGF Method.
+
+| Aspect | Composable Business | Reuse Enablement |
+|--------|---------------------|------------------|
+| Focus / Orientation | _How business capabilities are composed, orchestrated, and evolved_ | _How knowledge assets and components are packaged and shared_ |
+| Primary Question | "How do we assemble business capabilities from reusable parts to adapt to change?" | "How do we design those reusable parts so they can be assembled safely and meaningfully?" |
+| Scope | Business and operational level — orchestrating Use Cases, Personas, and Stories into composable outcomes. | Technical and semantic level — creating and governing reusable artifacts: ontologies, datasets, shapes, workflows, data products, and Stories. |
+| Key Mechanism | **Use Case Tree (UCT)** as _the orchestration layer_: composing and aligning modular business capabilities. | **Use Case Tree (UCT)** as _the packaging layer_: publishing reusable components and metadata to the Enterprise Knowledge Graph (EKG) for discovery and re-use. |
+| Relationship to the EKG | The EKG provides the shared semantics and service interfaces that make cross-use-case orchestration possible. | The EKG provides the shared identifiers, ontologies, and provenance that make reuse safe and traceable. |
+| Value Proposition | Agility and adaptability: the ability to reconfigure the enterprise dynamically in response to change. | Efficiency and consistency: the ability to reduce duplication and accelerate delivery through reusable, versioned components. |
+| Primary Users | Business and solution architects; transformation leads. | Data and knowledge engineers; ontology and platform teams. |
+| Outcome | Composable business capabilities and adaptive workflows. | Reusable semantic components and data products. |
+| Relationship to Each Other | Composable business **depends on** reuse. Without reusable components, there is nothing to compose. | Reuse **finds purpose** in composability. Without higher-level composition, reuse is just technical hygiene. |
+
+!!! tip "Two sides of the same semantic coin"
+
+    **Reuse Enablement** creates the *building blocks*.
+
+    **Composable Business** assembles them into *living systems*.
+
+    Both rely on the **Use Case Tree (UCT)** as the semantic package
+    manager of the Enterprise Knowledge Graph — governing how business,
+    data, and technical artifacts are versioned, discoverable, and
+    composable.
+
+## How to Enable Reuse in Practice
+
+1. **Model once, reuse everywhere:** design ontologies, shapes, and
+   stories as modular assets stored and versioned in the EKG.
+
+2. **Publish via the UCT:** register components as packages with clear
+   ownership, metadata, and dependency relationships.
+
+3. **Govern for trust:** validate with SHACL, record provenance, enforce
+   entitlements and lifecycle policies.
+
+4. **Discover and compose:** make all reusable artifacts searchable and
+   connectable across domains and teams.
+
+5. **Measure reuse:** track adoption, version dependencies, and impact
+   metrics to sustain continuous improvement.

+
+## Summary
+
+Reuse Enablement is how the EKG turns knowledge into infrastructure.
+By packaging every use case, ontology, and data product as a governed,
+discoverable component within the Use Case Tree, the enterprise builds a
+foundation for **scalable intelligence and composable business**.
+
+When reuse becomes second nature, innovation stops reinventing the wheel
+— and starts accelerating on shared semantic ground.
