Enterprise Architecture As Strategy
Occasionally you stumble across a body of work that completely maps to what you are doing at that moment and it brings you to a complete new understanding of your activity.
A couple of years ago some colleagues and I were trying to assemble everything we knew or could find on business systems consolidation. The idea was to be able to put some real meat on the bones of the Single Instance message that Oracle had been taking to the market for some time. We had had some significant project successes and some failures as well. We wanted to understand what might be special about single instance/ERP consolidation projects and structure that knowledge so that our customers could also benefit from it.
Then I happened upon Enterprise Architecture as Strategy by Ross, Weill and Robertson. This book helped me come to a much richer understanding of enterprise architecture maturity and how this concept binds a given business operating model to the underlying IT architecture that supports it.
Basically it explained to me how some consolidation projects had a great chance of succeeding while others would carry a substantial risk of failure from day one, simply due to a mismatch between the desired (enterprise) architecture and the maturity of it’s implementation in the client organization.
Here is a quick summary of why the Enterprise Architecture concept is important.
