I said 'an established' pipeline. I don't believe the analogy is ever used in the 'you want the first one in a month' way, because there's myriad other ways to say it's idiotic to just go out hiring if you need something done stat.

(Primarily: short-term, hires will reduce productivity, because established colleagues see an increase in the amount of support & knowledge-sharing they need to do, reducing their output by more than the new hire can yet offer.)
