TOGAF Framework

Core Idea

TOGAF (The Open Group Architecture Framework) is a comprehensive enterprise architecture framework that provides a systematic methodology for designing, planning, implementing, and governing enterprise IT architecture through its Architecture Development Method (ADM).

TOGAF Framework

TOGAF is an enterprise architecture framework developed by The Open Group, first released in 1995 based on the U.S. Department of Defense’s TAFIM model. Adopted by 80% of Global 50 companies and 60% of Fortune 500 companies as of 2016, it is the dominant enterprise architecture framework.

Unlike modeling languages that define notation, TOGAF is a methodology framework answering “how do we build enterprise architecture?” rather than “how do we visualize it?”

The core is the Architecture Development Method (ADM)—a cyclic, iterative process of 9+1 phases guiding organizations through the complete architecture lifecycle. It operates at multiple levels of iteration: across the entire process, between phases, and within each phase, allowing organizations to customize to their maturity level.

TOGAF addresses architecture across four domains:

• Business Architecture — organizational structure and business processes
• Application Architecture — application systems and their relationships
• Data Architecture — logical and physical data assets
• Technology Architecture — hardware, software, and network infrastructure

Supporting components include the Enterprise Continuum (taxonomy for classifying architecture artifacts), the Architecture Repository (structured storage for architecture assets), and guidelines on governance, principles, and deliverables.

Relationship with ArchiMate

TOGAF and ArchiMate are complementary standards from The Open Group. TOGAF provides the process (the “how”); ArchiMate provides the modeling language (the “what to draw”). ArchiMate’s three core layers—Business, Application, and Technology—map directly to TOGAF ADM Phases B, C, and D. ArchiMate’s Strategy/Motivation and Implementation/Migration extensions align with the remaining phases.

In practice, enterprise architects use TOGAF to establish the architecture development process and governance structure, then use ArchiMate to create standardized visual models at each ADM phase.

Why This Matters

Enterprise architecture requires both systematic methodology and effective communication. TOGAF provides structured approach that ensures nothing is overlooked in complex, organization-wide transformations and prevents ad-hoc, fragmented architecture practices. Its widespread adoption also creates a common vocabulary across organizations, enabling architects to share practices and collaborate effectively.
