The Open Group Architecture Framework (TOGAF) is a globally recognised framework for enterprise architecture. The release of the TOGAF Standard, 10th Edition marks a significant update from the previous version, TOGAF 9.2. This new edition reflects shifts in technology, business practices, and the need for a more adaptable approach to enterprise architecture. Below is a consolidated overview of the key differences between TOGAF 9.2 and the TOGAF Standard, 10th Edition.
1. Structure and Organisation
Modular Structure vs. Monolithic Document
- TOGAF 9.2: Presented as a single, comprehensive document, which could be overwhelming due to its size and complexity.
- TOGAF 10th Edition: Introduces a modular structure, dividing the framework into smaller, more manageable guides. This allows organisations to adopt and update specific parts more easily, addressing areas of interest more effectively. The modular format supports frequent updates and makes the framework more accessible.
2. Emphasis on Agility and Flexibility
Iterative and Agile Approach
- TOGAF 9.2: The Architecture Development Method (ADM) was often perceived as a linear, prescriptive process. While adaptable, it lacked emphasis on iterative development.
- TOGAF 10th Edition: The ADM remains central but is now presented as more iterative and adaptable, promoting agile principles. It encourages tailoring the ADM to specific project needs, revisiting previous phases as necessary, and fosters a more flexible approach to architecture development.
3. Focus on Digital Transformation and Modern Technologies
Incorporation of Emerging Trends
- TOGAF 9.2: Focused on traditional IT architectures with limited guidance on digital transformation and emerging technologies like cloud computing, IoT, AI, and microservices.
- TOGAF 10th Edition: Acknowledges the importance of digital transformation, providing guidance on supporting digital initiatives. It incorporates considerations for emerging technologies, modern business models, and provides strategies for integrating them into enterprise architectures.
4. Enhanced Business Architecture Guidance
Alignment with Business Strategies
- TOGAF 9.2: Included business architecture but did not emphasise it heavily compared to other domains.
- TOGAF 10th Edition: Places greater emphasis on business architecture, recognising its crucial role in driving IT decisions. It provides expanded guidance on modelling business capabilities, value streams, and organisational structures, helping align architectures with business strategies and objectives.
5. Simplification and Clarity
Improved Accessibility
- TOGAF 9.2: Contained dense language and complex concepts, making it challenging for newcomers.
- TOGAF 10th Edition: Simplifies language and clarifies concepts to enhance understanding. Definitions have been refined, and a comprehensive glossary helps practitioners communicate more effectively, reducing misunderstandings.
6. Updated Content Framework
Streamlined Artefacts and Deliverables
- TOGAF 9.2: Provided a detailed content framework but was criticised for complexity.
- TOGAF 10th Edition: Introduces an updated content framework that is more streamlined and practical. It is aligned with real-world use cases and modern organisational needs, focusing on outcome-oriented use of the framework.
7. Enhanced Guidance and Resources
Practical Implementation Support
- TOGAF 9.2: Offered foundational principles but limited practical implementation guidance.
- TOGAF 10th Edition: Provides enhanced, practical guidance on implementing the framework effectively. It includes case studies, examples, and best practices illustrating real-world application, bridging the gap between theory and practice.
8. Security and Risk Management
Integration into the Architecture Process
- TOGAF 9.2: Addressed security and risk management but not in extensive detail.
- TOGAF 10th Edition: Gives security and risk management more prominence, with detailed guidance on integrating these considerations into the architecture development process. This reflects the growing importance of cybersecurity in enterprise environments.
9. Terminology and Definitions
Consistency and Clarity
- TOGAF 9.2: Used a range of terminology that could be unfamiliar or inconsistent.
- TOGAF 10th Edition: Updates and refines terminology to reflect current industry practices and improve clarity. Simplified definitions and consistent language make the framework more accessible to a wider audience.
10. Stakeholder Engagement and Communication
Emphasis on Collaboration
- TOGAF 9.2: Included stakeholder management but provided limited guidance on communication strategies.
- TOGAF 10th Edition: Emphasises the importance of engaging stakeholders and effective communication. It offers tools and techniques for identifying stakeholder concerns, managing expectations, and ensuring architecture initiatives are understood and supported across the organisation.
11. Certification and Training Updates
Modular Certification Path
- TOGAF 9.2: Provided guidance on certification and training focused on mastering the core framework.
- TOGAF 10th Edition: Introduces a more modular certification path aligning with its modular structure. This allows for focused certifications in specific areas such as digital transformation or agile architecture, offering tailored career paths for professionals.
12. Integration with Other Frameworks
Compatibility and Alignment
- TOGAF 9.2: Integration with other frameworks was possible but not explicitly guided.
- TOGAF 10th Edition: Enhances alignment with other industry standards and frameworks like ITIL, COBIT, and Agile methodologies. This integration facilitates a cohesive approach to governance and management across different organisational domains.
13. Sustainability and Environmental Considerations
Inclusion of Modern Concerns
- TOGAF 9.2: Limited mention of sustainability and environmental factors.
- TOGAF 10th Edition: Incorporates guidance on embedding sustainability and environmental considerations into the architecture development process, reflecting the growing importance of these issues in business strategies.
14. Focus on Value Delivery and Outcomes
Business Value Alignment
- TOGAF 9.2: Tended to be process-oriented with less emphasis on measuring value or outcomes.
- TOGAF 10th Edition: Places a stronger focus on delivering business value and achieving tangible outcomes. It encourages continuous alignment of architecture work with business goals and demonstrates the benefits of architectural decisions through measurable results.
15. Enhanced Architecture Development Method (ADM)
Adaptable and Iterative Process
- TOGAF 9.2: Presented the ADM as a core, linear method.
- TOGAF 10th Edition: Updates the ADM to be more iterative and adaptable. It emphasises tailoring the ADM to specific project needs, promoting agile principles, and revisiting phases as necessary. This reflects a shift towards a more practical and flexible approach suitable for modern organisations.
16. Support for Enterprise Agility
Responsiveness to Change
- TOGAF 9.2: Provided a solid foundation but was less adaptable to rapidly changing environments.
- TOGAF 10th Edition: Enhances support for enterprise agility, recognising the need for organisations to respond quickly to market and technological changes. It guides maintaining architectural rigour while enabling flexibility and speed.
17. Industry-Specific Guidance
Tailored Content
- TOGAF 9.2: Adaptable but lacked industry-specific guidance.
- TOGAF 10th Edition: Includes more industry-specific guidance, offering templates, case studies, and best practices tailored to sectors like finance, healthcare, and government. This helps organisations apply the framework more easily in their specific contexts.
18. Enhanced Treatment of Emerging Technologies
Integration into Architecture
- TOGAF 9.2: Did not explicitly address many emerging technologies.
- TOGAF 10th Edition: Provides guidance on integrating emerging technologies such as AI, machine learning, and microservices into enterprise architectures. It acknowledges the impact of these technologies and offers strategies for their inclusion.
Summary
The TOGAF Standard, 10th Edition represents a significant evolution from TOGAF 9.2. It modernises the framework to better suit the demands of contemporary enterprise architecture by:
- Adopting a modular structure for flexibility and ease of use.
- Emphasising agility, iterative development, and alignment with agile methodologies.
- Enhancing guidance on digital transformation and integrating emerging technologies.
- Focusing on business value, stakeholder engagement, and effective communication.
