I think the GP's point is exactly that: With a physical contractor, you want it done, to spec, as quickly as possible. Anyone can tell that B is a better bricklayer than A, because we can see that the same work got done, but more efficiently, and are happy because we had to pay them less.

With software, it's hard for people to tell that the finished product for Team B is as good as (or better than) that made by Team A, and therefore all they can look at is often effort. They see team A responding to alerts, alarms, production issues, etc, all night and weekend, and then see you cruise out at 5.
