Steven Sinofsky, on the Zero Defect policy that Microsoft attempted to institute in 1989:

Melissa [Birch] also connected some dots for me and explained that the way groups were rewarding people who ultimately contributed more bugs than code was in practice rewarding some men and penalizing some women on the team. Teams that were small had few women. There was no hiding that fact. Melissa’s view was that the women were routinely delivering the code they said they would, when they said they would, and at the same time getting feedback about the need to do more.

An evergreen issue that keeps being discovered anew, it would seem.
