However, I also believe that is orthogonal to the question of whether productivity should be measured or not. You're correct, as taking that to it's end conclusion would imply it's impossible to improve (which I'm sure most would disagree with). Perhaps the question "How do you measure improvement?" is relevant. This might be a roundabout way to yield the former.
