Up front: I believe that Lines of Code is a USELESS metric. However, people are often shocked by the raw number of lines of code that are written each day by a developer. What’s your guess? 1,000? 200? Try just under 20. This is basically the number of lines of code in a released project divided by the number of programmer days, so, just because you can write 1,000 buggy lines of code per day, that doesn’t make you productive! 🙂 It’s the post bug-fix, post integration testing, post-everything lines that count. (You can find some background here and here.)
