Enterprise Architecture

Unified enterprise & software architecture skill grounded in four open-source standards — C4 + Structurizr DSL, ArchiMate 3.x, TOGAF ADM, and arc42 + ADRs (MADR). Use it whenever the user wants to: produce architecture diagrams as code (C4 context/container/component, Structurizr, PlantUML, Mermaid); write architecture docs or decision records (arc42, ADRs/MADRs, design docs); review or assess a design against quality attributes and EA principles; or model an enterprise (capabilities → applications → technology, app landscapes, portfolio rationalization). Trigger it even when no framework is n

# Enterprise Architecture

A practical toolkit for doing real architecture work the way open-source EA standards
intend it — diagrams as code, documentation as code, decisions as records, and a single
traceable model underneath. It unifies four complementary frameworks so you reach for the
right tool at the right altitude instead of forcing everything into one notation.

## The mental model: four frameworks, four altitudes

These frameworks are not competitors — they answer different questions. Knowing which one
fits the question is most of the skill.

| Framework | Question it answers | Altitude | When to reach for it |
|---|---|---|---|
| **C4 model** | "How is *this software system* structured?" | System → code | A single system/service: context, containers, components |
| **ArchiMate** | "How does the *whole enterprise* hang together?" | Business → app → tech | Capabilities, app landscapes, cross-system flows |
| **TOGAF ADM** | "How do we *deliver* an architecture change?" | Process/governance | Running an architecture engagement end-to-end |
| **arc42 + ADRs** | "How do we *write it down* so others understand & decisions stick?" | Documentation | Documenting a system; recording a decision |

A useful rule of thumb: **C4 zooms into one system, ArchiMate zooms out to the
enterprise, TOGAF is the *method* for changing it, and arc42/ADR is how you *narrate* it.**
They compose: an arc42 doc embeds C4 diagrams and links ADRs; a TOGAF engagement produces
