I suspect a lot of bad design comes from a myopic focus on The Analytics. Yes, there were a lot of failures in the bad old days due to Big Design Up Front and only iterating once a year after you ship 1.0, but we've gone to the opposite extreme. A lot of organizations seem to just jerk and twitch as the raw numeric results come in, with no central cognition.

Build for the future you want, don't just head for the local minima. Take risks and damn the statistics.
