This book is not consistently aligned to CObIT (Control Objectives for IT), which is an IT governance standard set forth by the IT Governance Institute (paste the ASIN, B0001F8V14, into the search all products box on this page). However, it does provide a realistic approach to governance that reflects successful practices developed and employed by 250 companies surveyed by the authors. The key differences between CObIT and the approach in this book is the stakeholder model presented versus the control model CObIT incorporates. More importantly, the authors approach more effectively aligns IT to business goals and objectives, with IT in a supporting role more than as the primary decision maker.
Among the points the authors make is that IT is a strategic asset, and effective governance links IT to strategy and performance. I fully agree with this approach, and especially like the recommendations the authors make for implementing and managing IT governance, as well as the resources in the appendix which show which companies were surveyed.
If you are following CObIT you may have issues with this book; however, if you read through it with an objective mind you will find that the approach will work effectively, and does come closer to IT-business alignment than the CObIT approach.
