Visual Atlas — Maps 8–10
Map 8 — Vertical vs horizontal model linkage
ENTERPRISE CONCEPT
↑ ↓
ENTERPRISE LOGICAL
↑ ↓ ↔ peer model/entity
PROJECT LOGICAL ↔ same-level model
↑ ↓
PROJECT PHYSICAL
VERTICAL = changes abstraction altitude
HORIZONTAL = stays at same abstraction level
Interpretation: vertical mapping creates traceability from implementation to enterprise meaning. Horizontal mapping preserves same-level cross-model/Subject Area relationships.
Source: pp. 107–108.
Map 9 — Project architecture loop
SCOPE
enterprise alignment • reuse • dependencies
↓
REQUIREMENTS
entities • sources • availability • quality • value
↓
DESIGN
enterprise constructs • standards • target specifications
↓
IMPLEMENT
BUY | REUSE | BUILD
↓
FEED BACK
return reusable/new enterprise knowledge to architecture
↺
Interpretation: architecture is not a gate that appears at the end. It shapes project decisions and harvests valid enterprise learning from delivery.
Rebuild check: under Implement, classify Buy/Reuse/Build correctly.
Source: pp. 114–115.
Map 10 — Architecture governance alignment
| Role / mechanism | Primary architecture connection |
|---|---|
| Data Architect | Business liaison; enterprise requirements, blueprints, standards, design oversight. |
| Data Steward | Business meaning, Subject Area/entity accountability, governance alignment. |
| Project Team | Uses/improves architecture assets and implements solutions to applicable standards. |
| Portfolio / Enterprise Architecture | Sequences priorities so funded change moves toward target architecture. |
| Data Governance | Decision rights, oversight, standards, visible exception paths. |
Business / Governance intent
↕
Architect ↔ Steward
↕ ↕
Project delivery ↔ Portfolio / EA
↺ reusable knowledge + governed decisions
Interpretation: no single actor owns everything. Architects do not become the business meaning owner or the project implementation team. Governance does not replace architecture execution.
Source: pp. 115–116, 120.
Final visual test
Without looking, rebuild Maps 4, 5, 6, 7, and 9, then state one changed fact that would change a classification in each.
