Yesterday evening, my new Whitebook about Agile Enterprise Architecture (see here, in Dutch) got published. In this Whitebook I pointed out that developing Enterprise Architecture is a Two Way process. And that it should be build Agile.
First of all, a Business Case should be leading in the choices that are made in the architecture. This is, simply, because we look at architecture from a project point of view. A project start architecture needs to be the beginning of a project, but measured against the organization. This is exactly the problem I encounter on a near daily basis: Enterprise Architecture made too big and becoming an ideal picture instead of an realistic and facilitating process.
Enterprise Architecture basically needs to describe the Business processes, the information demand, the applications overview and the technical grounds. This is the blueprint on which we can build our system. But how can we make sure we don’t overdo it? Simple: make it Agile.
Agile Enterprise Architecture works on the same principles as Agile Software Development: the Agile Manifesto. When we understand these principles, building an architecture for our project and organization is made a lot simpler: look at the stuff we actually need right now, don’t over document the process and let people be the basis of knowledge.
In other words: Agile Enterprise Architecture is a Two Way process in which the entire group of stakeholders is leading. Therefore it starts with the basics: why do we need it. (and what don’t we need, eliminating waste.) In Agile Enterprise Architecture there is room to learn and adjust, because we don’t do everything at once, but listen to what all stakeholders have to say: what can IT learn from Business, and the other way around.
