I'm hoping someone from Google can chime in and say whether Google's really measuring each employee's productivity, and, if so, how they're doing it.
I've been involved in efforts to measure my team's productivity using function point analysis and LoC measurements, but both felt like bogus measures.
It doesn't seem like Google would use either of these measures, given their engineering culture, so I'm genuinely curious as to how they do it.
