TEAF maturity diagnostic

Position your organization on the seven-level TEAF maturity pyramid in six minutes, and identify your two most urgent priorities.

The collection

The TEAF collection

The four books that formalize the method, from the strategic manifesto to operational implementation — V1 of the collection, now complete. All available on Amazon, in paperback and Kindle; Books I to III also as a 3-book series — see the series.

Cover — TEAF — Book I: The Digital Nervous System Manifesto
01

TEAF — Book I: The Digital Nervous System Manifesto

The thesis and the vocabulary: why enterprise architecture stops being a document and becomes a living system. For boards, CIOs, CEOs, CTOs.

  • Five axioms and five laws on the pace of governance
  • Nine enterprise architecture anti-patterns
  • The seven-level maturity pyramid

Born from the same pattern seen mission after mission: boards fund transformation, CIOs deliver projects, and the gap between intent and the reality of systems keeps widening. A dedicated section precisely distinguishes what TEAF inherits from TOGAF, ITIL, COBIT and SAFe, what it adapts, combines, and what remains unique to it.

TEAF — Book II: Framework Specification

The complete technical specification for architects: the eight-component metamodel, artifacts, patterns and anti-patterns, governance.

  • The metamodel and its eight components, in detail
  • The artifacts: Living ADR, Knowledge Graph, Digital Twin, Capability Map
  • Eight patterns, nine anti-patterns, the five TEAF roles

Also contains the terminology reference for TEAF's eleven structuring vocabulary terms — whose fixed definitions the site's knowledge base reuses — as well as the five founding axioms and the five laws of AI-native architecture.

Cover — TEAF — Book III: The Practitioner's Guide
03

TEAF — Book III: The Practitioner's Guide

Concrete deployment, mission after mission: the four operational phases, playbooks and case studies. For consultants and ops teams.

  • The four-phase method: Why / What / How / Who-When
  • Playbooks for recurring situations (architecture review, migration, security, FinOps)
  • Five fictional scenarios to illustrate the method

Its Part IV provides directly actionable checklists — NIS2/AI Act/GDPR compliance audit, security, human-in-the-loop, data provenance — reused in interactive form on the site's Diagnostic page.

Kindle: coming soon
Cover — TEAF — Book IV: Operational Implementation Guide
04

TEAF — Book IV: Operational Implementation Guide

The practical guide for experimenting with and deploying TEAF in a real environment: scoping a POC, starting with TEAF Light, extending progressively. For executives, CIOs, architects and consultants.

  • The 1-1-1 principle applied step by step: scoping a POC, its objectives and success criteria
  • The progressive rollout of the Loop's eight components, without a new documentation layer
  • Adoption trajectories, from POC to broader deployment, for SMBs, mid-size and large organizations

Its pedagogical throughline — intelligent invoice processing — illustrates a complete end-to-end TEAF Loop; like the scenarios in Book III, it is explicitly presented as a fictional construction, not a real engagement outcome.

Open source

TEAF Light — the lightweight implementation

Book IV (Operational Implementation Guide) introduces the 1-1-1 principle — one process, one loop, one measurable objective — and a reference stack accessible to a small team (Dolibarr, GitLab, PostgreSQL/pgvector, n8n, Python, Cloudflare). Its practical content also lives in the TEAF Light open-source repository, the free, executable version of the 1-1-1 principle.

White paper

The TEAF synthesis in one document

A short synthesis of the framework — genesis, eight-component loop, central thesis and what remains to be validated — for a first read before the full collection. Available in both languages, regardless of the site's displayed language.

Upcoming webinars & talks

Sessions are in preparation on the following topics — no date set yet: an introduction to TEAF and the eight-component loop, getting started with TEAF Light and the 1-1-1 principle, governing AI agents with the AI Control Plane, and a transparent assessment of what TEAF has proven in the field after one year.
