Bugs vs. changed LOC could be a good one. I believe there have been studies showing that bugs are proportional to LOC, but don't quote me on that. The nice thing about his data is that it's fairly well controlled (for software, anyway)--we can separate his contribution vs. others' and his code pre- and post-TDD. I agree that his analysis isn't great, though. Also, it's hard to account for effect of legacy code. The big drop in bug count doesn't happen until 5 quarters after he started TDD. |
