I can think of two: supply chain management (producing stuff more effectively) and market trend analysis (know what people will buy tomorrow - to build it when it's needed). The first involves a lot of people networking and dealing with the messy bits (hard) while the later is looking into the crystal ball with help of some data to extrapolate likely outcomes (somewhat hard).

There is also logistics (again tons of messy bits), customer service (interacting with people), transportation (now this is probably the lowest hanging fruit - which is why everyone and their dog is chasing it).

Just of the top of my hat.. of course there is R&D (hard), design (hard), bureaucracy (bookkeeping, process management, etc. - easy in theory, not so much in practice) -- well, and all the other things that we humans do during a day of business.

We could also involve politics, government and philosophy - but that would probably be stretching it.

ps. I also suck at counting, so maybe that too.
