which may actually be the problem. I suspect that there is actually some ideal ratio that could be calculated of Input Fields / Dev, LoC / Devs, or maybe Unique Pages / Dev, or some mix of all of the above. Some of the metrics I hear out of places like airbnb absolutely blow my mind (>5000 engineers! wtaf are they all doing?!?). I can sort of see the #s at google, MS making sense given the breadth of the problems they are solving, but other places, not so much.
