Ross, Weill and Robertson take a top down, strategic view of the enterprise architecture space. I like this broad scope and extremely practical view of how successful enterprises implement and view IT. In short the book brings IT to the center of defining and building the enterprise execution system with extreme care over where agility should be sought and where a capability should be locked into place.

This is NOT a book about technology. Rather it seeks to use MBA language to build a common ground between the business and technology.

Ross, Weill and Robertson define four basic types of operating model - Coordination, Unification, Diversification, and Replication. From a Citrix point of view each of these has implications for how a Citrix Delivery Center brings value.

My question --- does anyone care about this stuff (EA as Strategy) beyond the Enterprise Architecture crowd?
