"Enterprise Architecture Made Simple"
by Håkan Edvinsson; Lottie Aderinne
Pranaam! to everyone. The authors provide a nice perspective of placing information models, process models and deriving architecture models from these. The fundamental theme shared throughoutby the authors is considering 'Information' aspect of business that doesn't change as frequently as processes or systems. IT is too narrowly focused on systems and believing that is the only way to improve an enterprise. But the enterprise wide picture is clearer if once takes a step back and considers what the most value adds for business and where should the next significant transformation happen in this enterprise. A management and leadership who understands this will initiate EA in enterprise, so that larger picture is evangelised at various levels in organization and such that EA is thought leadership that consistently convinces everyone on next steps.
Authors have used Zachman 3.0 Framework. They have succeeding in providing a very clear and to the point steps in preparing today's EA, making them ready to deal with different scenarios.
The EA methodology has been broken into 3 parts viz: Ready - Prepare EA, Set - operationalize EA and Run - action as EA. The discussion is basically an expansion of top phases
in TOGAF9 which deals with Requirements phase, Initiating Architecture work(gathering sponsorship) and Business Architecture. The finer details of rest of architecture phases
are left out in favor of Information architecture and business process modeling, since these have most profound impact to business and consulting to top management and business leaders.
The language n book is to the point, straight on topic rather than exaggeration usually found on EA topics. I liked this 'Enterprise Architecture Made Simple' very much and would recommend this to anyone interested in EA. Regards. SGN
