What is enterprise architecture? Definition and method for the AI era

Knowledge base

TEAF's structuring vocabulary

Eleven terms that make up TEAF's vocabulary, with their fixed definition as set by the collection's terminology reference. Two of them reuse a notion already present elsewhere in the industry — the caveat is stated explicitly rather than left unsaid.

Living Architecture

Architecture that evolves continuously through permanent feedback, rather than through periodic review cycles.

Digital Nervous System

A digital layer connecting strategy to execution in real time, by analogy with a biological nervous system linking perception and action.

The phrase is already used in enterprise architecture, notably by platform vendors. TEAF reuses this metaphor rather than inventing it.

Knowledge Backbone

The metamodel component that centralizes all architectural knowledge into a single repository, materialized concretely by the Knowledge Graph.

Living ADR

An Architecture Decision Record generated and updated automatically, permanently linked to the knowledge graph.

The "Living" status for continuously evolving ADRs already exists in some public repositories. TEAF proposes a formalization of it at enterprise-architecture scale.

Digital Twin

A dynamic representation of the architecture and its behaviors, continuously updated.

Continuous Governance

Governance built into the architecture lifecycle, with no separate audit phase.

Decision Fabric

The decisional fabric linking architecture decisions (ADRs), the knowledge graph and governance.

AI Control Plane

The control plane for AI agents: routing, security, cost governance.

Capability Graph

The graph of business, technical and compliance capabilities, and their mutual dependencies.

Strategic Graph

The graph linking board-level objectives to the technical components that serve them.

Architecture Intelligence Layer

An AI layer that learns from past decisions and proposes adjustments.
