"Enterprise Architecture As Strategy" (Amazon) by Jeanne W. Ross, Peter Weill, David Robertson is perhaps the most quoted book. Online forums on the topic quote this as one of the few really good references on the topic and I agree.
The authors do a great job of introducing and packaging concepts in Enterprise Architecture – operating model, maturity model, core diagrams, IT engagement model – that are referenced by EA practitioners, consultants and academics alike. The case studies based on academic research of over “200 companies” keeps the narrative grounded.
Who is this book for?
- Practicing Enterprise Architects and EA consultants will find the topics and case studies refreshing. It certainly got me reflecting on my employer’s target operating model
- The book speaks to business executives as much as it does to EA practitioners. Executives will also find it a handy reference that can equip them to “govern” IT strategies
- Those looking to get into EA (many IS/Technical Architects, business analysts and process consultants) will find the book a good introduction to EA “big picture” topics; and perhaps an introduction to some consulting jargon
The book is not an EA “cook book” or a “how to” guide. Unfortunately, learning how-to-do-EA will only come with experience and a few grey hair.
