An overly rigid EA governance is prone to producing a rampant bureaucracy of approvals and sign-offs. From experience we know that a sign-off rarely means that the matter is really closed. The approved document is usually not questioned or openly disregarded. Instead, the reality on the ground—in the IT department, in the projects implementing parts of an IT transformation—slowly creeps away from the documented status. The predominant effect reached by too much focus on formal governance is that the EA group and the executors on the ground just stop talking to each other.

And why can’t that complexity be managed well by a traditional top-down, up-front planning approach? We establish a theoretical foundation to reason out these questions. With a brief reference to management, organization, and evolution theory, we arrive at the Edge of Chaos concept that we have already outlined briefly. This idea further leads us to introduce the EA Dashboard that combines the EA caricatures from the preceding section with the Edge of Chaos concept. The EA Dashboard serves as a yardstick against which to measure successful EA practices.

The architecture serves this purpose by providing distinct views of the system, each view addressing the specific interest or concern of a specific stakeholder group.

ARCHITECTURE The Definition of Architecture Architecture is the representation of the structure and behavior of a system and its constituent parts, plus a set of principles that guide the system’s long-term evolution.
