Negative 2000 Lines of Code (1982)
I know lines of code as a measure of productivity has been criticized to death here and elsewhere but today I went and did some analysis on past two years of my team members contributions and saw the team members that I know they are productive are modifying code a ton more than others. It can be subtraction of code too but overall more changes correlated with my perception of their contributions. My perception is pretty informed because I'm their manager and I know this team and this code base very well.
