What is TOGAF? Architecture & Enterprise Architecture

TOGAF stands for The Open Group Architecture Framework. It is owned and maintained by The Open Group — a global consortium of 700+ member organizations. Currently in its 10th Edition, TOGAF is used by 80%+ of Fortune 500 companies as their EA framework.

• ▸Provides a common vocabulary for EA
• ▸Defines a method for developing architecture: the ADM (Architecture Development Method)
• ▸Includes reference models: TRM (Technical Reference Model) and III-RM (Integrated Information Infrastructure Reference Model)
• ▸Provides tools, techniques, and governance guidelines
• ▸✅ FREE to use within any enterprise — Open Group membership is NOT required to apply TOGAF
• ▸📄 The TOGAF Standard (10th Edition) = the TOGAF Fundamental Content (six free-standing documents) + a collection of TOGAF Series Guides that give practical guidance for specific needs

TOGAF uses the ISO/IEC/IEEE 42010 definition:

"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."

• ▸Architecture is about STRUCTURE + RELATIONSHIPS + PRINCIPLES
• ▸It answers: What exists? How do things relate? What rules govern changes?

In TOGAF, "Enterprise" does NOT mean "big company." It means:

"Any collection of organizations that have a common set of goals."

• ▸Could be a single department, a full organization, or a group of organizations
• ▸Could be government, private, NGO, startup — any entity pursuing shared objectives
• ▸Example: Digital University Kerala as a whole IS an enterprise; so is just the CDIPD department

TOGAF covers four interconnected domains — always in this order. Click each domain below to explore it:

The TOGAF Standard is not just the ADM — it has six interconnected components. The ADM is the core; the rest support and extend it:

• ▸⚙️ Architecture Development Method (ADM) — The CORE. An iterative process built from the Preliminary Phase and Phases A–H, with Requirements Management at the centre, for developing EA
• ▸📋 ADM Guidelines & Techniques — Supporting techniques: gap analysis, stakeholder management, risk management, business scenarios
• ▸🗂️ Architecture Content Framework — Defines what to produce: deliverables, artifacts, and building blocks (ABBs & SBBs)
• ▸🔄 Enterprise Continuum & Tools — Classifies architecture assets from generic (Foundation) to org-specific; includes the Architecture Repository
• ▸📚 Reference Library — Pre-defined reference architectures: TRM (Technical Reference Model) and III-RM (Integrated Information Infrastructure)
• ▸🏛️ Architecture Capability Framework — Guidance on establishing and operating an EA practice within an organization
