I said that there was no need for a “modern” “theory of leadership.” Well, I do believe that. But I did miss a big point. “Old” “command & control leadership” was not the best way to get things done—even in the “old” days. But now it’s more: “Command & control leadership,” circa 1980, circa (alas) 2007, simply will not work in an age of widespread, global collaboration (wikinomics, crowdsourcing, etc.). So the “people-centric,” “engagement-centric,” “personal growth-centric,” “service-servant based” “models” of leadership are … not optional!
