Why TOGAF Isn’t Enough: A Case Study In Real Enterprise Architecture
Summary
This exploratory case study delves into how a large organisation utilised TOGAF as a foundation for its enterprise architecture (EA) but ultimately crafted a customised model that delivered tangible value. The article explores which parts of the TOGAF framework were retained and which were abandoned, offering actionable insights for effective EA practices.
Enterprise architecture is regarded as a strategic enabler, promising clarity, alignment between business and IT, and a cohesive roadmap for digital transformation. As the most widely used EA framework, TOGAF aims to provide a structured approach to achieve these objectives. However, the practical application within a complex organisation often deviates from theoretical ideals, leading to a disconnect between prescribed methodologies and actual practices.
In this case study, a technology-driven organisation adopted TOGAF with widespread certification across the architecture staff, enjoying executive support. However, the actual implementation revealed that key elements of the framework, such as the Architecture Development Method (ADM), were impractical. Instead, the organisation developed a lightweight, context-driven architecture practice focusing on collaboration and outcome-driven approaches, demonstrating that adaptability trumps rigidity.
Key Points
- TOGAF’s formal adoption does not guarantee compliance with its methodologies in practice.
- Organisations often retain only high-level concepts from frameworks while discarding their structural elements.
- Effective EA requires a tailored approach that aligns with the organisation’s culture, governance, and operational pace.
- Frameworks like TOGAF can become ineffective if they do not translate into actionable, stakeholder-centric practices.
- Successful enterprise architecture prioritises outcomes and adaptability over strict adherence to formal models.

This case study is essential for CIOs and IT leaders navigating the challenges of aligning IT strategy with operational realities. It illustrates how one organisation transformed its approach to enterprise architecture by prioritising contextual intelligence over rigid frameworks. The insights offered can assist leaders in building architecture functions that are practical, responsive, and aligned with business goals.
