Why TOGAF Isn’t Enough: A Case Study In Real Enterprise Architecture
This exploratory Enterprise Architecture case study examines how a large organisation used TOGAF as a starting point but ultimately created a customised enterprise architecture model. It explains what parts of the framework were kept, what was discarded, and how the organisation built an EA practice that delivered real value—offering actionable lessons.
Enterprise architecture (EA) has long been positioned as a strategic enabler—its promise: clarity amid complexity, alignment between business and IT, and a coherent roadmap for digital transformation. TOGAF, the most cited and adopted EA framework globally, purports to offer the blueprint for achieving these outcomes. However, a rigorous case study of a large, technology-forward institution shows the challenges faced when applying TOGAF in practice.
This organisation systematically set aside elements of TOGAF, including the Architecture Development Method (ADM), deeming them impractical. Instead, a more adaptable architecture practice emerged that emphasised responsiveness and stakeholder engagement over rigid compliance. By focusing on value delivery rather than adherence to a framework, the organisation reimagined its enterprise architecture, crafting customised documentation that served real planning functions.
Key Points
- Adherence to TOGAF does not guarantee following its methodology in practice.
- Organisations often keep only high-level concepts while discarding TOGAF’s structure and processes.
- Successful EA requires adapting methods to fit the organisation’s culture and governance.
- Frameworks like TOGAF can become symbolic if they fail to translate into actionable practices.
- True success in enterprise architecture comes from adaptability and a focus on delivering value.
