Think you know something about how to manage IT? Care to learn a thing or two about how not to do it?

My latest article for InfoWorld revisits an old theme, originally covered in 2004 by Chad Dickerson, InfoWorld’s then-CTO: the top IT mistakes to avoid. We all fall prey to bad ideas once in a while. Presented here are twenty doozies for you to observe and evade.

And lest you think you’ve heard it all before, rest assured that this year’s list doesn’t overlap much with the original 20. Some of the topics are related, but I’ve tried to present a new twist or an opposite angle. Taken together, the two articles form a pretty formidable list of “worst practices.” So click on over and let me know what you think.
