Architecture Model

An architecture model abstracts selected aspects of the enterprise—structure, behavior, or motivation—using a defined notation and meta-model. Models support gap analysis, impact assessment, and stakeholder communication at appropriate levels of detail. Executable models linked to live metadata increase accuracy over static diagrams.

In Practice

Larkinized LLC establishes modeling conventions—layers, colors, naming—to enable team-scale collaboration in EA tools. Models should tie to repository objects and version history for auditability. Over-modeling wastes effort; focus on models that answer specific decisions.

Example

An application dependency model highlights single points of failure before approving a data center consolidation program.
