In my last startup we used 3 Measures for productivity. Number of functions/procedures/methods, Number of lines of non-comment code and the number of defects found in the code. I wrote far more code than anybody else in the company. I took on all the really hard stuff that other developers had already failed at. My number of defects per line of code and per function/procedure/method was always lower than all the other developers. So I would choose to politely disagree. You can measure productivity.
