The TOGAF® Standard, a Standard of The Open Group

The TOGAF Standard is a proven enterprise methodology and framework used by the world’s leading organizations to improve business efficiency.

This Document

This document is a TOGAF® Series Guide: The TOGAF® Leader’s Guide to Establishing and Evolving an EA Capability. It has been developed and approved by The Open Group.

This Guide puts forward advice on establishing an Enterprise Architecture (EA) Capability that aligns to a set of requirements and expectations specific to each enterprise. It proposes an approach for the standing-up and enhancing of an enterprise’s EA Capability based upon the established best practice contained within the TOGAF® standard, a standard of The Open Group.

This Guide is structured to provide the context, content, and rationale behind choices and steps that an EA Leader can consult at any point in time to set up, operate, or improve the value extracted from the practice of EA in the organization.

The intended audience for this Guide is as follows:

• Professionals who have been tasked with establishing and evolving an enterprise’s EA Capability

• Business Leaders who are contemplating an investment in EA as a strategy

• Strategy and technology advisors to an enterprise’s Leaders

• Professionals and experts who are enthusiasts in the field of EA or organizational transformation

This Guide is written directly for the person who is tasked with developing, sustaining, and evolving an EA Capability that delivers what their enterprise needs.

A high-functioning EA Capability optimizes Boundaryless Information Flow™ within and between enterprises based on open standards and global interoperability.

About the TOGAF® Series Guides

The TOGAF® Series Guides contain guidance on how to use the TOGAF Standard and how to adapt it to fulfill specific needs.

The TOGAF® Series Guides are expected to be the most rapidly developing part of the TOGAF Standard and are positioned as the guidance part of the standard. While the TOGAF Fundamental Content is expected to be long-lived and stable, guidance on the use of the TOGAF Standard can be industry, architectural style, purpose, and problem-specific. For example, the stakeholders, concerns, views, and supporting models required to support the transformation of an extended enterprise may be significantly different than those used to support the transition of an in-house IT environment to the cloud; both will use the Architecture Development Method (ADM), start with an Architecture Vision, and develop a Target Architecture on the way to an Implementation and Migration Plan. The TOGAF Fundamental Content remains the essential scaffolding across industry, domain, and style.

Part 1: Introduction

1    Introduction

This Guide presents advice on establishing an Enterprise Architecture (EA) Capability that aligns to a set of requirements and expectations that are specific to each enterprise.1 It proposes an approach for the standing-up and enhancement of an enterprise’s EA Capability based upon established best practices. This approach follows a configured path through the TOGAF® Architecture Development Method (ADM).

This Guide is written for the EA Capability Leader, the person who is tasked to lead the effort to establish or evolve an EA Capability. We have selected the term Leader deliberately to reflect the role rather than any one of the myriad titles in an enterprise the Leader may have. This Guide is structured to provide the context, content, and rationale behind choices and steps that an EA Leader can consult at any point in time to set up, operate, and improve the value extracted from the practice of EA in the organization. A high-functioning EA Capability optimizes Boundaryless Information Flow™ within and between enterprises based on open standards and global interoperability.

Practicing EA requires in-depth interaction with several specialized functions such as strategy development, HR policies, and corporate accounting. This Guide:

• Introduces key topics of concern

• Defines the terms related to the topic

• Shows the terms that are related to an EA Capability

• Discusses what the Leader needs to know

• Describes what the Leader should do with this knowledge

This Guide transitions its focus between setting up a new EA Capability practice and evolving or re-establishing the practice. It is presented this way to reflect the reality of the state of EA prevalent in the industry at the time of writing.

This Guide is divided into six parts.

Part 1 (this part) is the introduction, including an assessment of the state of EA, definitions, and key concepts used in this Guide.

Parts 2 and 3 present a narrative that leads the reader through a series of topics and related steps to assist in stepping back from the current operational context to seek a broader perspective. Ideally, the contents of these first two parts should form a companion to the TOGAF ADM or similar architecture development processes, methods, or frameworks that an enterprise may choose to adopt. This Guide takes this approach deliberately. It focuses on outcomes without being distracted by implementation or evolution. This is done by simply focusing on what must be done and what needs to be achieved out of the steps.

Part 4 covers adoption of the EA Capability. This includes preparation and initiation activities required to establish or enhance the EA Capability that would be relevant to an enterprise.

Part 5 shows a simple mapping of how the TOGAF ADM can be practically used. This follows a “configuration” of the TOGAF ADM for architecting and establishing an EA Capability. It serves as an example to show how the TOGAF ADM could be customized to address the purpose for which an EA Capability is being established.

Part 6 contains appendices.

Not all scenarios or related fields discussed in this Guide will be relevant for every enterprise, and especially in the first attempts at creating an EA Capability. Establishing any capability is an iterative process. This Guide is intended as a starting point to create or evolve an EA Capability, when the purpose for performing EA changes, or when the charter for a team changes.

Even though this Guide has a logical structure, it is not designed as a simple task-list. The depth and detail of every step taken by the EA Leader is iterative, and the only variable is time spent for each step. As with all change work, listing what you need to know is not the same as defining the level of detail in documentation. This Guide provides a concise summary of what you need to know to establish the EA Capability in Table 9.

It is the EA Leader’s judgment to consider the level of depth and documentation and how to iterate in a manner that best suits an enterprise. The intent of this Guide is that you read Chapter 4 (Enterprise Context and EA Context) and Chapter 5 (Business Objectives for the EA Capability) before making any judgment call on the approach to building an EA Capability.

Experience has shown that there is no one right EA Capability model. There are numerous examples of EA Capability being focused on strategy or portfolio or project or a combination of these. EA Capability has been aligned to organizational change leaders, supporting specific transformation efforts, or has focused on continuous improvement and change or embedded within an IT organization. This Guide will help the Leader of an EA Capability to identify an approach that is:

• Appropriate to the enterprise

• Appropriate to the context of the EA Capability

• Appropriate to the purpose of the EA Capability

This Guide presents a tailored approach to establish and evolve EA Capability, aligned to the TOGAF Preliminary Phase. The EA Capability is designed to deliver architectures for a purpose and to drive effective change. However, when presenting the concepts supporting each of the steps, the Guide presents a few leading alternative techniques and approaches. It is up to the Leader to identify and employ concepts or school of thought that best meets the needs of the enterprise.

The importance of aligning an enterprise’s context to its purpose is paramount. It is dubious to suggest that there is a single, correct approach to align context to purpose and this Guide makes no suppositions to that effect.

1.1 How to Use this Guide with the TOGAF Framework

The TOGAF framework provides essential universal scaffolding useful to a range of organizations, industries, and architectural styles. Customization of the TOGAF framework is necessary to align to the enterprise’s requirements and expectations. The question is how to customize the TOGAF framework.
