Enterprise Architecture Matters

Adrian Grigoriu

Enterprise adaptation to technology change is key to survival

Vote 0 Votes
The enterprise is stable at its core. It has been so for centuries. The invariability of value chains and process frameworks stand proof of that. Key business strategies are also few and well known: diversification, expansion in markets and creation of new products.

The abstract business operation of an enterprise changes little in time as such.
And so does the business architecture tier of the enterprise architecture (EA).

An enterprise though is realised only through its people and technology.
The overall architecture of an enterprise consists, beside business architecture, in technology architecture and people organisation that describe the way specific resources implement the abstract business operation documented in the business architecture.

Still, the functionality embedded in technology and the type of organisation structure often determine, to a degree, the business structure and operation.
It's rare today that you establish upfront, in detail, the operation of a function and then develop the application that implements it. Today we buy or rent applications that come with embedded, predetermined business functionality.
Business strategy has to take always into account as such the evolution of the applications technology.

Thus, I would state that what mainly drives the enterprise capabilities, products and markets is the technology and its change, which pace increasingly accelerates as Kurzweil observed: "the rate of change doubles every ten years".

That renders adaptation to technology change a key factor in the survival of the enterprise.
In turn, EA plays the key role in the change process by documenting the enterprise and facilitating the analysis, enabling correlation between programs and the projection of the future states of the enterprise.
