Project Management. I once was working with two CS professors in a UK university. One was full of words (let's call him A). The other was one of the brilllian minds in UI science that helped design the Nokia phones' keypads (let's call her B). Most people disliked B because she had a start, middle, end. She required timelines, milestones, deliverables. Because of that everyone working with her was getting better grades, was more productive, because she was helping people manage themselves better. Prof A had the lazy ones the "deep thinkers, but not the doers.

One thing that (many) academics lack is project management skills. This is why many (that I know) sit on a desk, with a mountain of papers, having a thousand things unfinished. Try doing that in an actual business and see how it plays out..

Being a good teacher doesn't make you a good project manager.
