I find that with large forts the "rolling resource shortage" problem is really obnoxious. Things like "oh, my idiots turned all the wood, the wood I needed for beds, into charcoal" get my goat. Actually solving the steel shortage problem is really difficult; ERP is not a bad comparison for that, which is made especially difficult because as your dorfs get better at tasks they get significantly faster. A master armorsmith can kill 100 bars of steel in very short order.

I will admit I have more sophisticated desires / needs, though.
