The Open Group Architecture Framework (TOGAF) is a comprehensive framework for enterprise architecture (EA) that provides a common language, methodology, and tools for designing and managing an organization’s architecture.

TOGAF is maintained by The Open Group, a global consortium that promotes open standards and best practices in information technology. The framework consists of four main components:

1. Architecture Development Method (ADM): a step-by-step methodology for developing and implementing an enterprise architecture, which includes phases such as visioning, gap analysis, and implementation planning.
2. Architecture Content Framework: a model for organizing and structuring architectural artifacts, including models, diagrams, and documents, into a set of standard building blocks.
3. Architecture Capability Framework: a set of tools, techniques, and processes for building and managing an architecture capability within an organization, including governance, stakeholder management, and knowledge management.
4. TOGAF Reference Models: a set of standard models for different domains of architecture, such as the TOGAF Business Footprint model, which provides a framework for analyzing an organization’s business operations and processes.

TOGAF is widely used by organizations of all sizes and industries to guide their architecture development and align their business and IT strategies. It is often used in conjunction with other frameworks, such as ITIL and COBIT, to support comprehensive IT management practices.
