TOGAF (The Open Group Architecture Framework) is one of the most widely used enterprise architecture frameworks, providing a structured approach to design, plan, implement, and govern an organization's enterprise architecture. TOGAF has evolved over time, and the most recent version, TOGAF 10, represents a significant update from TOGAF 9. Below is a comparison of TOGAF 9 and TOGAF 10, focusing on their key differences and updates.
TOGAF 9
TOGAF 9 Overview
Released in 2009, TOGAF 9 introduced several major enhancements over the previous versions and became the dominant version used by organizations globally. It is highly regarded for its structured approach, known as the Architecture Development Method (ADM), which helps organizations develop and manage their enterprise architectures.
Key Features of TOGAF 9:
Architecture Development Method (ADM):
Central to TOGAF 9, the ADM is a step-by-step approach to enterprise architecture that includes phases such as preliminary, architecture vision, business architecture, information systems architecture, technology architecture, and implementation governance.
Content Framework:
Provides a standardized way of organizing architectural deliverables, artifacts, and building blocks to help structure complex architectures.
Enterprise Continuum:
TOGAF 9 emphasized the use of the Enterprise Continuum and Architecture Repository to categorize and manage the reuse of architectural assets.
Focus on Four Architecture Domains:
Business Architecture: How the business processes and organization are structured.
Data Architecture: Data management and data flow within the organization.
Application Architecture: Applications and software systems and their interactions.
Technology Architecture: The IT infrastructure (hardware, software, networks).
Framework Adaptability:
TOGAF 9 provided guidelines for tailoring the ADM and framework to an organization's specific needs.
TOGAF 10
TOGAF 10 Overview
TOGAF 10, released in 2022, marks a major update to the framework, reflecting the shifts in technology and business trends, such as digital transformation, cloud computing, agile development, and DevOps. It simplifies and modernizes the framework to address contemporary challenges and provide more flexibility.
Key Features and Enhancements in TOGAF 10:
Modular Structure:
TOGAF 10 is more modular and flexible, making it easier to adopt only the parts that are relevant to an organization's needs. This modularity helps architects use just the sections they need for specific projects without getting bogged down in the entire framework.
Core Content and Extended Guidance:
TOGAF 10 has a core structure that provides essential guidance, and it includes extended guidance that can be used depending on the organizational context (e.g., Agile, Digital, Cloud).
The framework splits into a Core that covers the fundamental aspects of TOGAF and a series of guides to handle different specializations like security, risk, or emerging technologies.
Focus on Agile and Digital Transformation:
Agility and speed of delivery are key focuses in TOGAF 10. It incorporates methods and tools for enterprise architects to work in agile environments, reflecting the rise of Agile methodologies, DevOps, and iterative development practices.
Simplified ADM:
The ADM remains central to TOGAF, but in version 10, it is made more flexible to better suit modern enterprises and project needs. There is more emphasis on iteration and reuse in architectural work.
Emphasis on Governance and Risk Management:
Governance has been given greater emphasis, especially in the context of digital transformation and how to manage risks associated with newer technologies like cloud computing.
Improved Usability and Relevance:
TOGAF 10 is designed to be easier to adopt, with clearer guidance and more practical advice. The language and structure have been simplified to be more accessible to practitioners at various skill levels.

It focuses on being more business outcome-oriented, emphasizing the value that enterprise architecture can bring in driving organizational success.
New Reference Architectures:
Updated reference architectures in areas like digital technology, cloud, and security, making it easier to adapt TOGAF to modern IT environments.
Expanded Ecosystem of Guides:
TOGAF 10 comes with an expanded set of supporting materials called TOGAF Series Guides, which are available to supplement the core content. These cover specialized topics such as agile, digital strategy, business architecture, and security architecture.
TOGAF Series Guides
The TOGAF Series Guides are a set of supplementary documents introduced with TOGAF 10 to provide detailed, practical guidance on specific topics relevant to enterprise architecture (EA). These guides support the modular and flexible approach of TOGAF 10, enabling organizations and architects to focus on areas of interest without needing to dive into the entire framework.
The Series Guides cover a variety of topics, ranging from specialized architectural practices to emerging trends and technologies. They allow enterprise architects to access more targeted and practical advice for specific industries, methodologies, or technical domains, making TOGAF easier to adopt and more adaptable to contemporary IT and business challenges.
