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 retained, 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 provide the blueprint for achieving these outcomes. Yet, when a framework designed for universality confronts the messy particularities of real organisations, a divide often occurs between theory and execution.
The case study details a large, technology-driven organisation where TOGAF was initially adopted as the official EA foundation. However, despite widespread certification and executive endorsement, the organisation systematically set aside key components of TOGAF, finding them impractical in their specific context. Instead of rigid compliance, they embraced a more responsive, stakeholder-centred architecture approach.
This shift resulted in a bespoke architecture practice that focused on creating meaningful outputs for decision-making, embedding EA into funding, technology standards, and project design. Instead of following TOGAF’s prescriptive models, the organisation developed flexible documentation that reflected their actual operations and success metrics.
Key Points
- TOGAF’s framework was not fully adhered to; many elements were disregarded in practice.
- The organisation developed a lightweight architecture practice prioritising flexibility and collaboration.
- Documentation was tailored to support real planning and governance needs, moving away from theoretical checklists.
- Key roles, such as engagement managers, were established to facilitate communication and align strategic intents with actionable requirements.
- The case highlights the necessity of contextual intelligence over doctrinal adherence in EA frameworks.

This article is crucial for CIOs and IT leaders grappling with the complexities of enterprise architecture. By showcasing a real-world case where traditional frameworks like TOGAF fell short, it provides valuable insights for building more adaptable, stakeholder-focused EA practices. This is particularly relevant for leaders seeking to align strategic goals with practical execution in evolving business environments.
