Shovels or Bulldozers?

Here's a quick thought for the day... Give 40 people each a shovel and you'll move quite a lot of dirt.  Give a few of them a bulldozer and you'll find those people get exponentially more work accomplished, but a project built that way will end up with certain parts moving much faster than others.  What if you gave all 40 people a bulldozer?  Lots more work could get done (potentially).  Or, you might argue, why do you need 40 people when fewer people can complete the job using the more powerful equipment?  Exactly.
