Enterprise Architecture Matters

The enterprise architecture development should be  evaluated to  assess1. its scope, if it covers the whole enterprise or at least it plans to, starting with the parts specifically demanded. A reference (business) architecture would be necessary to compare to. 2. the artifacts fitness for... Read More..
I post here in response to this post of Gartner's: "Enterprise architects: Please leave your framework at the door".Please don't, that is, leave the EA framework at the door. You do it at your own peril.Because a good framework is like the... Read More..

EA, as the name states, is the architecture that is the integrated blueprint of the enterprise. It, simply put, describes the enterprise from the many angles that serve its various stakeholders.Hence, EA, as an architecture, is to be employed... Read More..
Architecture, in general, is about models and blueprints. Hence, enterprise architects have to devise models that describe the enterprise.  Based on these models many people in the enterprise visualize, analyze and solve their own issues, in context. Because you... Read More..
