Every year many corporations that have grown sluggish and are headed downward are rebuilt. And how? By changing a handful of executives at the top. Companies (and colleges and churches and clubs and unions and all other types of organizations) are successfully rebuilt from the top down, not from the bottom up. Change the thinking at the top and you automatically change the thinking at the bottom.
