IT is hard enough already - why do things you don't need to?

Galen Gruman in Infoworld:

I don't get why IT itself takes on so many management challenges unrelated to technology operations or strategy.

Yes, it's not a good use of limited resources. But I don't think the problem of taking on things that don't need to be done is unique to IT.

Looking at IT for an answer to this is misplaced; instead, I'd start by looking at psychology, both organizational and individual.
