Open Group Architecture Framework

The Open Group Architecture Framework (TOGAF) is an enterprise architecture framework that provides a structured approach, methods, and reference content for designing, planning, implementing and governing enterprise information technology architectures.

Expanded Explanation

1. Technical Function and Core Characteristics

TOGAF defines a modular enterprise architecture method and supporting tools that organizations use to develop enterprise architectures. It includes a content framework, a detailed method known as the Architecture Development Method, and guidance on building and maintaining architecture capability.

The framework structures architecture into domains, including business, data, application and technology architectures. It also provides reference models, metamodels, and techniques for requirements management, architecture governance, capability mapping and migration planning.

2. Enterprise Usage and Architectural Context

Enterprises use TOGAF as a common language and process to align business strategy with IT architecture and solution delivery. It supports architectural governance, architecture boards and standardized artifacts across projects, programs and portfolios.

Organizations apply TOGAF alongside project management, service management and software development methodologies to coordinate long-term architecture roadmaps, target states and transition architectures. It also supports integration with standards-based models, regulatory requirements and internal control frameworks.

3. Related or Adjacent Technologies

TOGAF relates to other enterprise architecture approaches, such as the Zachman Framework, federal and defense architecture frameworks, and various industry-specific reference architectures. It also aligns with standards and practices from ISO and other standards bodies on architecture and systems engineering.

Security and risk practitioners often use TOGAF with security architecture standards and frameworks, including ISO information security standards and NIST guidance. Data and cloud architects may integrate TOGAF with data management, cloud reference architectures and integration frameworks.

4. Business and Operational Significance

TOGAF provides a repeatable architecture process and standardized deliverables that help organizations coordinate change across business, data, applications and technology. It supports cost control, portfolio rationalization, interoperability, and governance of technology investments.

Executives, enterprise architects and security leaders use TOGAF artifacts and processes to support decision-making on platforms, sourcing, risk, compliance and digital initiatives. It also underpins role definitions, skills frameworks and training for architecture functions.
