I was disappointed by this book. While its central thesis (that MIS should include human and political considerations, not just technical ones) is valid and needs championing, I found the text repetitive, lacking in clear advice, and full of buzzwords used to restate the obvious. Mr. Davenport is clearly an expert on how to run MIS at large companies. Unfortunately, I found it difficult to glean applicable lessons from his book.
I found this to be a useful and informative book with new insights, especially in the area of developing a wholistic view of an information enterprise. Most previous books seem to be limited to just MIS departments and ignore the fact that managing information is not something that just happens in a vacumn. I also found the diagnosis section to be useful and grounded in real work versus the "blackboard" consulting suggestions that sometimes comes from academics whose ideas are not grounded in real world experiences.
