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, real-world implementation often diverges from this ideal.
Case Study Overview
In this case study, a technology-forward institution adopted TOGAF as its official EA foundation, but soon discovered that many elements of the framework were impractical for their specific context. Instead, the organisation developed a more adaptable approach that emphasised collaboration and stakeholder engagement over rigid methodologies.
Key Insights
- Declaring adherence to TOGAF does not equate to following its methodology in practice.
- Organisations often retain only high-level concepts from EA frameworks while discarding structured processes.
- Practical EA requires tailoring methods to the organisation’s culture, governance, and pace.
- Frameworks like TOGAF risk becoming symbolic if they fail to translate into actionable practices.
- Real enterprise architecture success stems from adaptability, contextual design, and a relentless focus on delivering value.
