Today's heads of big companies are as recognizable to us as the most popular entertainers or sports stars, but the heart and soul of every organization are those leaders below the CEO. Today's celebrity CEO has become either a figurehead or an egomaniac, and often too public a personality to get the real work done. That work is done instead by teams of leaders-exceptional deputies who forge great partnerships to maximize both organizational and personal success.

Heenan and Bennis believe we must look beyond the Bill Gateses of the world to understand what makes an organization excel.
