I bought this book as I wanted to compare the methods I had been using to devise enterprise architecture with other industry practice.
I found myself struggling to understand the book. Not because it was describing something technical complex, more because the authors seem to be trying to explain everything in the most verbose manner and using as many obscure long words as possible.
For sure the book describes important concepts and models, some of which I have added to my own methods. But I felt I was fighting the book to gain understanding.
Clarity is everything in books with a technical theme and the language this book uses is far from clear.
