Over the holidays, I read a lot about Deming, just-in-time inventory, and how if you have "multiple inspectors" of an output it works worse than one inspector, because all the inspectors will assume the other one has checked the work, and regardless, nobody wants to be the one inspector that makes the others look bad.

Compare and contrast with how I need 3 VPs, a manager, a director, a lawyer, and a finance person to sign off on a small contract to pay an open source developer for some work.
