Possibly from the same source but one useful thing I learned was to do with check lists. Rather than ticking a box to say how many scalpels you used, is the tyre pressure OK etc etc you write down the number. The persons doesn't just say yes OK, they write down the pressure. That [generally] ensures they have actually measured it and got a real value.
