Preface

The Open Group Architecture Framework (TOGAF) — Version 9, Enterprise Edition — is an open,
industry consensus framework and method for enterprise architecture.
This Document
There are seven main parts to the TOGAF document:
PART I

(Introduction) This part provides a high-level introduction to the key concepts of enterprise
architecture and in particular the TOGAF approach. It contains the definitions of terms used
throughout TOGAF and release notes detailing the changes between this version and the
previous version of TOGAF.

PART II

(Architecture Development Method) This is the core of TOGAF. It describes the TOGAF
Architecture Development Method (ADM) — a step-by-step approach to developing an
enter prise architecture.

PART III

(ADM Guidelines & Techniques) This part contains a collection of guidelines and techniques
available for use in applying TOGAF and the TOGAF ADM.

PART IV

(Architecture Content Framework) This part describes the TOGAF content framework,
including a structured metamodel for architectural artifacts, the use of re-usable architecture

building blocks, and an overview of typical architecture deliverables.

PART V

(Enter prise Continuum & Tools) This part discusses appropriate taxonomies and tools to
categorize and store the outputs of architecture activity within an enterprise.

PART VI

(TOGAF Reference Models) This part provides a selection of architectural reference
models, which includes the TOGAF Foundation Architecture, and the Integrated Information
Infrastructure Reference Model (III-RM).

PART VII

(Architecture Capability Framework) This part discusses the organization, processes, skills,
roles, and responsibilities required to establish and operate an architecture function within
an enterprise.

Intended Audience
TOGAF is intended for enterprise architects, business architects, IT architects, data architects, systems
architects, solutions architects, and anyone responsible for the architecture function within an
organization.
Keywords
