Enterprise Architecture Matters

Adrian Grigoriu

The scope of Enterprise Architecture

Vote 0 Votes
EA, extended to or over its limits, maybe about strategy, transformation and in general about all things related to an Enterprise, depending on whom you are talking to. In practice though, an architecture is a set of integrated blueprints.

Let's take an example: a city has an urban architecture described by blueprints illustrating residential and industrial areas, parks, public building, roads, transport, pipes and cable networks etc. 

If you consider the city an Enterprise, that is include people, then you may add the operation of the city that is, how does it deliver medical services, how does it clean the streets etc. 

Now, the town officials devise strategies to develop the city for the next 100 years and plan the tactics to improve it etc. But are these strategies, tactical plans and transformation programs part of the architecture? 

They are definitely not part of the city architecture or map, as we know it. They are not part of a City Enterprise Architecture that describes the current city operation. They maybe partly part of the future city architecture, if there is one. 
But the strategic transformation execution, is it part of City Enterprise Architecture?

It depends on how you define EA and its scope. Who establishes the scope? It ultimately comes down to your definition, expectations and the EA lead level of authority (usually not at all). 
To start with, I think that there will be quite a virulent reaction from the top enterprise management and business when if trying to include business transformation programs under EA. Strategy had also been in existence long before EA was born. Business would expect the transformation to use an EA blueprint, but would not expect EA to take over the Enterprise transformation and install an Enterprise Architect as CEO.
