Sports fans are familiar with the phrase "Stats are for losers." If your favorite team got hammered last Sunday you can count on a few people jumping into a discussion with an argument about how the team "should have won because we outgained the other guys 500 yrds to 250 blah blah blah..." The simple rejoiner from the winning side is, "Stats are for losers."
I was thinking about this in the context of an agile project that was comparing its iteration point count with another team's. "Yeah, we got 25 points last iteration, the other guys only got 21." Agile practitioners know that if you're doing estimating correctly, the points are only measures of relative effort, comparable only to the team's effort within a release. They can't be used to compare to, for example, another team's point estimate. The team that was congratulating itself had delivered a design that was flawed (and they knew it) but didn't fix it once the flaw was pointed out, because it would have affected their point count.
Stats are for losers. Winning means delivering high quality product that is of value to the business, not having a high score on some arbitrary measure like points.
