Interesting analysis by the management team at Google. The basic argument appears to be that you don't hire as the boss the person with the best technical skills. You hire the "people person." I guess most of us knew that intuitively, but it's nice to have that conclusion confirmed with more data. And for a technical type like myself, that's a bit of a challenge to me to figure out what changes I might want to make as a leader and how.
