Beschreibung

This is the official Pocket Guide for the TOGAF® Standard, 10^th Edition from The Open Group. Building on over 25 years of development and constant input from The Open Group Architecture Forum’s global community of Enterprise Architecture thought leaders, the TOGAF Standard, 10^th Edition expands the material available to architecture practitioners to make adoption of best practices easier. With greatly expanded guidance and “how-to” material, it enables organizations to operate in an efficient and effective way across a broad range of use-cases, including Agile enterprises and Digital Transformation. The TOGAF Standard 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. This official Pocket Guide provides an overview of the contents and purpose of the TOGAF Standard in a condensed form. As such it does not cover every aspect of the standard in detail, but provides highlights and key reference information. Topics covered include:

• A high-level introduction to the TOGAF Standard, introducing the modular TOGAF documentation set, the TOGAF Library, and the TOGAF framework
• Guidance on how to read the standard
• An introduction to the general how-to information provided in the TOGAF Standard, including guidance for practitioners, and how to use the standard in the Digital Enterprise
• An overview of guidance to support the establishment of an Enterprise Architecture team
• An overview of the guidance provided in the TOGAF Standard for specific topic domains, including Security Architecture, Business Architecture, Data/Information Architecture, Agile Methods, and Reference Models and Methods
• An introduction to the TOGAF Fundamental Content documents provided in the TOGAF Standard, which describe the concepts considered to be universally applicable to the TOGAF framework, including:

• Key techniques of the ADM cycle
• Guidelines for adapting the TOGAF ADM for different usage scenarios
• The Architecture Content Framework
• Enterprise Architecture Capability and Guidance
• The TOGAF Architecture Development Method (ADM), including summary phases for each of the ADM phases
• An overview of ADM deliverables

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

• An overview of the TOGAF Standard

• The TOGAF Library

• An overview of the TOGAF framework

• How to read the standard

1.1. Introduction to the TOGAF Standard

The TOGAF Standard is a framework for Enterprise Architecture. Put simply, it is a standard approach for developing, approving, using, and maintaining Enterprise Architectures. It applies to all Enterprise Architecture practices. 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 the TOGAF Standard, 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 the TOGAF Standard at regular intervals and published each one on The Open Group public website. Successive versions have represented the current state of stable, scalable, best practice.

This version builds on previous versions of the TOGAF Standard, expanding and updating the material available to architecture practitioners to assist them in building a sustainable Enterprise Architecture.

1.2. Structure of the TOGAF Documentation

The TOGAF documentation set is structured to address the transition from common universal concepts to the unique configuration within an organization. It includes the formal TOGAF Standard and a broader body of knowledge in the TOGAF Library, as shown in Figure 1.

The TOGAF Standard represents today’s stable, scalable, best practices, with concepts and guidance that apply across industries, scale, and pace of change. This is expected from a standard – proven practices, stable concepts, and being actionable. The TOGAF Standard provides a body of proven practices addressing its broad uses. The TOGAF Fundamental Content includes the universal concepts of Enterprise Architecture. The TOGAF Series Guides take these concepts and make them actionable. Together, the TOGAF Fundamental Content and the TOGAF Series Guides are the TOGAF Standard.

Figure 1. The TOGAF Documentation Set

The intent of dividing the TOGAF Standard into these separate documents is to allow for different areas of specialization to be considered in detail and potentially addressed in isolation. Although all the constituent documents work together as a whole, it is also feasible to select particular documents for adoption while excluding others.

The TOGAF documentation set structure is modular. There is a clear hierarchy from the universal concepts in the TOGAF Fundamental Content, to the stable best practices in the TOGAF Series Guides, to emerging ideas in the TOGAF Library. The structure of the TOGAF documentation set makes the adoption of your optimal method easier.

1.3. An Overview of the TOGAF Standard

Figure 2. The TOGAF Standard

The TOGAF Standard applies to all Enterprise Architecture practices. It does not matter whether your architecture will support strategy, portfolio, project, or solution delivery, or whether it is about embarking on a Digital Transformation or legacy simplification. The TOGAF Fundamental Content and TOGAF Series Guides provide enduring, stable, universal concepts, and proven best practices.

1.3.1. The TOGAF Fundamental Content

The TOGAF Fundamental Content consists of six documents as shown in Table 1. Central to the TOGAF Fundamental Content is the TOGAF Architecture Development Method (ADM), which provides a tested and repeatable process for developing architectures.
