This is the official Pocket Guide for the TOGAF® Standard, Version 9.2, from The Open Group. It is published in hard copy and electronic formats by Van Haren Publishing. The TOGAF Standard, a standard of The Open Group, is a proven Enterprise Architecture methodology and framework used by the world's leading organizations to improve business efficiency. It is the most prominent and reliable Enterprise Architecture standard, ensuring consistent standards, methods, and communication among Enterprise Architecture professionals. Those professionals who are fluent in the TOGAF approach enjoy greater industry credibility, job effectiveness, and career opportunities. The TOGAF approach helps practitioners avoid being locked into proprietary methods, utilize resources more efficiently and effectively, and realize a greater return on investment.

Chapter 1

Introduction

This chapter provides an introduction to the TOGAF standard, an open, industry consensus framework for Enterprise Architecture.

Topics addressed in this chapter include:

• An introduction to the TOGAF standard

• The structure and content of the TOGAF documentation

• The kinds of architecture that the TOGAF framework can be used to address

1.1 Introduction to the TOGAF Standard

The TOGAF standard is a framework for Enterprise Architecture. Put simply, it is a standard approach for assisting in the acceptance, production, use, and maintenance of Enterprise Architectures. It is based on an iterative process model supported by best practices and a re-usable set of existing architectural assets.

The TOGAF standard is developed and maintained by members of The Open Group, working within the Architecture Forum. The original development of TOGAF Version 1 in 1995 was based on the US Department of Defense Technical Architecture Framework for Information Management (TAFIM). Starting from this sound foundation, The Open Group Architecture Forum has developed successive versions of TOGAF at regular intervals and published each one on The Open Group public website.

This document covers the TOGAF Standard, Version 9.2, first published in April 2018. It is an update to the TOGAF 9.1 Standard to provide additional guidance, correct errors, address some structural challenges, and remove obsolete content. A description of the changes is provided in Appendix A.

The TOGAF standard can be used for developing a broad range of different Enterprise Architectures. It complements, and can be used in conjunction with, other frameworks that are more focused on specific deliverables for particular vertical sectors such as Government, Telecommunications, Manufacturing, Defense, and Finance. A key part of the TOGAF standard is the method – the TOGAF Architecture Development Method (ADM) – for developing an Enterprise Architecture that addresses business needs.

1.2 Structure of the TOGAF Documentation

The TOGAF documentation consists of the TOGAF standard, and a portfolio of guidance material, known as the TOGAF Library, to support the practical application of the standard.

The TOGAF standard is divided into six parts, as summarized in Table 1.

Table 1: Structure of the TOGAF Standard

Part I: Introduction	This part provides a high-level introduction to the key concepts of Enterprise Architecture and, in particular, to the TOGAF approach. It contains the definitions of terms used throughout the standard.
Part II: Architecture Development Method	This part is the core of the TOGAF framework. It describes the TOGAF Architecture Development Method (ADM) – a step-by-step approach to developing an Enterprise Architecture.
Part III: ADM Guidelines and Techniques	This part contains a collection of guidelines and techniques available for use in applying the TOGAF approach and the TOGAF ADM. Additional guidelines and techniques are also in the TOGAF Library.
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 (ABBs), and an overview of typical architecture deliverables.
Part V: Enterprise Continuum and Tools	This part discusses appropriate taxonomies and tools to categorize and store the outputs of architecture activity within an enterprise.
Part VI: Architecture Capability Framework	This part discusses the organization, processes, skills, roles, and responsibilities required to establish and operate an architecture practice within an enterprise.

Accompanying the standard is the TOGAF Library. The TOGAF Library is a reference library containing guidelines, templates, patterns, and other forms of reference material to accelerate the creation of new architectures for the enterprise. It is structured as summarized in Table 2:

Table 2: Structure of the TOGAF Library

Section 1: Foundation Documents	Broadly applicable information relating to the subject of the TOGAF framework or Enterprise Architecture.
Section 2: Generic Guidance and Techniques	Information describing architecture styles and how the TOGAF framework and Enterprise Architecture can be adapted to exploit the characteristics of a more specific context.
Section 3: Industry-Specific Guidance and Techniques	Information describing how the TOGAF framework and Enterprise Architecture can be applied to meet the specific needs of a vertical industry segment.
Section 4: Organization-Specific Guidance and Techniques	Information describing how the TOGAF framework and Enterprise Architecture have been applied to meet the needs of specific enterprises.

1.3 What is Architecture in the Context of the TOGAF Standard?

ISO/IEC/IEEE 42010:2011² defines “architecture” as:

“The fundamental concepts or properties of a system in its environment embodied in its elements, relationships, and in the principles of its design and evolution.”

The TOGAF standard embraces but does not strictly adhere to ISO/IEC/IEEE 42010:2011 terminology. In addition to the ISO/IEC/IEEE 42010:2011 definition of “architecture”, the TOGAF standard defines a second meaning depending upon the context:

“The structure of components, their inter-relationships, and the principles and guidelines governing their design and evolution over time.”

1.4 What kinds of Architecture does the TOGAF Standard deal with?

The TOGAF standard covers the development of four related types of architecture. These four types of architecture are commonly accepted as subsets of an overall Enterprise Architecture. They are shown in Table 3.

Table 3: Architecture Types Supported by the TOGAF Standard

Architecture Type	Description
Business Architecture	The business strategy, governance, organization, and key business processes.
Data Architecture^3	The structure of an organization’s logical and physical data assets and data management resources.
Application Architecture	A blueprint for the individual applications to be deployed, their interactions, a...
