This book has introduces nice way to analyze current architecture level of an organization. I find it helpful as with this kind of model you can turn an abstract thing like enterprise architecture more tangible and it also provides means for pointing out the progress while you are seeking higher levels of maturity of architecture. Naturally you may need to adjust some of the measures defined in the model, but basic principles introduced in this book provide clear and good starting point.
We have utilized the ideas from this book successfully at same time also taking benchmark of our architecture maturity level in iCMG’s competition. The category we participated was “New service offering”. Basic story from us was business transformation that is supported by growing enterprise architecture maturity level. Naturally you need also committed and capable people to utlize the framework, it is not working alone.
This book was definitely interesting and useful reading. One open ended though after experiencing this book was: is there another stage after business modularity, which was defined as highest stage here. Also it would be interesting to figure out, if organizations in different industries actually can be happy with some of the earlier stages in this four level model.
