Why this book

Enterprise architecture is the practice of shaping an organization’s structure so that business strategy and technology work together effectively. That much is not in dispute. What goes wrong is everything after it.

There is a pattern to how EA practices fail. The models get more detailed, the governance gets heavier, and the people who make the real decisions stop showing up. The architecture is correct, and nobody uses it.

Why these two authors

Romano and Dietmar came to this book from opposite ends of the discipline. They do not share a vantage point, they share an approach.

Romano approaches enterprise architecture from the frontier: as a transformation strategist, platform engineer, and advocate for cybernetic, AI-augmented organizations, he defines what architecture must become in a world of continuous change. Dietmar approaches it from the inside: as a practitioner who has spent over two decades implementing, governing, and integrating architecture into the operational, regulatory, and security realities of large enterprises, from ERP landscapes to global identity frameworks.
