The Enterprise Architecture Definition Collection

It's interesting, at least to me, to get a sense for all the different definitions of enterprise architecture out there. So, over time, I will post other people's definitions of enterprise architecture (and their sources) as I run across them in the literature, blogs, and websites. Updated March 9, 2006.

Good Enterprise Architecture:

Poor Enterprise Architecture:

CIO Insight magazine (website), "Enterprise Architecture Fact Sheet"

Enterprise Architecture is an infrastructure and a set of Machines constructed in order to manage a chaotic, dynamic, unpredictable, complex, organic, prone to error, frustrating, Enterprise IT, which has to support an ever increasing, dynamic portfolio of products and services, through constant "ASAP, Now, Right-Away" modifications of business processes.

Enterprise architecture (EA) refers to the manner in which the operations, systems, and technology components of a business are organized and integrated. It defines many of the standards and structures of these components and is a critical aspect of allowing capabilities and their supporting applications to develop independently while all work together as part of an end-to-end solution. An EA consists of several compenent architectures which often go by different names. Some of the common ones are: business/functional architecture; data/information architecture; applications/systems architecture; infrastructure/technology architecture; operations and execution architecture.
