I first heard of Dean Meyer when I read his book Decentralization: Fantasies, Failings, and Fundamentals. From the title, you can guess what its about, but you'd be surprised by some of the conclusions. I had Dean out to Utah for a day with the IT Directors when I was Utah's CIO. He was a great facilitator and led us in some importance directions. If you're trying to do some reorganization of your IT department, then reading Dean's books is well worth your while and having him out for a visit is even better. I mention Dean because I just discovered that he's writing a column called Beneath the Buzz for CIO magazine. The first three deal with ITIL, governance, and portfolio management.
