TOGAF 10: Understanding the 7 Core Concepts

Introduction

TOGAF 10, the latest version of The Open Group Architecture Framework, is a crucial tool for IT companies and organizations looking to streamline their enterprise architecture practices. This article explores the seven core concepts of TOGAF 10, providing a comprehensive understanding of how they contribute to the efficient management and development of enterprise architecture.

Definition of Enterprise

In the context of TOGAF, the term “Enterprise” refers to any organization or group of organizations with a shared set of goals. This can include corporations, divisions within a company, partnerships, or any other entity with a defined mission. Enterprise Architecture (EA) involves the practice of analyzing, designing, planning, and implementing the architecture of the enterprise to achieve these objectives.

Architecture Domain (BDAT)

TOGAF divides enterprise architecture into four primary domains, collectively known as BDAT:

Business Architecture

Business Architecture focuses on business requirements. It outlines the structure and operation of an organization, including business goals, functions, processes, and organizational structure.

Data Architecture

Data Architecture pertains to the management of data, both physical and logical. It involves data assets, databases, data models, and the governance of data across the enterprise.

Application Architecture

Application Architecture describes individual applications and their interactions. It addresses software applications and their role in supporting business processes and functions.

Technology Architecture

Technology Architecture involves the IT infrastructure, including hardware, software, networks, and services. It ensures that the infrastructure supports the application and data requirements of the business.

ADM (Architecture Development Method)

The Architecture Development Method (ADM) is the core of TOGAF. It provides an iterative approach to developing and managing enterprise architecture, consisting of the following phases:

Preliminary Phase

Preparation and definition of the architectural framework.

Phase A: Architecture Vision

Establishing the architectural vision to align stakeholders and define the scope.

Phase B: Business Architecture

Developing the business architecture to understand the structure and operation of the organization.

Phase C: Information Systems Architectures

Creating data and application architectures that support business processes.

Phase D: Technology Architecture

Developing the technology architecture to ensure the IT infrastructure meets the needs of the business.

Phase E: Opportunities and Solutions

Identifying opportunities and solutions for improvement and innovation.

Phase F: Migration Planning

Planning the migration from the current state to the target architecture.

Phase G: Implementation Governance

Governing the implementation to ensure alignment with the architectural vision.

Phase H: Architecture Change Management

Managing changes to the architecture to maintain alignment with business goals.

Requirements Management

Continuous management of requirements to adapt to day-to-day changes.

Deliverables, Artifacts, and Building Blocks

Deliverables

Deliverables are formally released and approved outcomes of each phase, such as reports, architectural models, and design documentation. They provide specific input to subsequent phases or meet stakeholder needs.

Artifacts

Artifacts include models, diagrams, and documents that describe specific aspects of the architecture. They serve as means of communication and documentation for various stakeholders and can be catalogs, matrices, or diagrams.

Building Blocks

Building Blocks are reusable architecture components that can be combined to create more complex solutions, ensuring consistency and efficiency in architecture development.

Enterprise Continuum

The Enterprise Continuum is a conceptual model for classifying and organizing architectural artifacts. It includes:

Architecture Continuum

Covers architectures from specific to general, providing a framework for developing and maintaining a comprehensive set of architectures.

Solutions Continuum

Covers technology solutions and their implementations, ensuring alignment with the architectural vision and business needs.

The Architecture Repository

The Architecture Repository is a structured repository containing all information relevant to the enterprise architecture, including:

Metamodel Content

Metadata definitions that provide a framework for understanding and managing architecture data.

Architecture Landscape

Current, target, and transition architecture models that provide a comprehensive view of the enterprise architecture.

Reference Library

Reference models, guidelines, and best practices that support architecture development and governance.

Standards Information Base (SIB)

Architecture standards and guidelines that ensure consistency and compliance across the enterprise.

Governance Log

Logs of architectural governance decisions, ensuring transparency and accountability in architecture management.

Architecture Capability

Effective enterprise architecture requires a set of capabilities, including:

Organization

Organizational structures and roles that support the architecture.

Processes

Processes for developing, governing, and managing the architecture.

Information

Data and information necessary to support architectural decisions.

Tools

Software tools and technologies that facilitate architecture development and management.

Skills

Skills and training required for personnel involved in architecture, ensuring they have the expertise to develop and manage the architecture effectively.
