"I would recommend this book to ICT practitioners who are lost in the functional decomposition that is taking place in the ICT industry at the moment, and who want to get an understanding of the ""big picture"" and how they fit into it; to managers in both business and technology roles, who need to have a working framework for linking business to technology opportunities and a framework that can facilitate conversation between technical and non-technical managers at all levels; and to academics as a model rich with application and explanatory power that really deserves further investigation."
