Enterprise Architecture (EA)

This page provides a brief sketch of my present position on Enterprise Architecture, together with some links to some key blogposts.

See Forthcoming Events for future presentations and workshops on Enterprise Architecture and related topics. See Presentations for a selection of earlier material.

I have been interested in Enterprise Modelling and Architecture for a long time. In the early 1990s, I developed an Enterprise Modelling Methodology for ODP, which we called EMM/ODP. And my more recent work on such topics as the Component-Based Business, Service-Oriented Architecture and Organizational Intelligence has been informed by my understanding of enterprise architecture.

There are many Enterprise Architecture frameworks in circulation now (DODAF, FEAF, MODAF, PEAF, TOGAF, Zachman), and RM/ODP has rather gone out of fashion. These frameworks are useful, but I have some concern about the body of knowledge upon which they are based. I am sceptical of claims of Enterprise Architecture (as presently constituted) being either a Profession or a Science - although clearly some people hope to push EA in this direction.

I have many friends in the Enterprise Architecture community, and they are doing excellent individual work. However, I don't see a widespread or coherent understanding of the value of EA outside the ranks of EAs themselves, and I think this represents a serious threat to the future of EA in its present form. Therefore I think there is a very strong possibility that EA may vanish as a job title or department, and that the excellent and essential work carried out by EAs will reemerge under some other function.

In the meantime, I expect to engage strongly with Enterprise Architecture, and look forward to some productive and stimulating debate with open-minded practitioners.
