Just like the philosophers of old, today's gurus have their own individual management bent, their own following, their own claims to fame. If you're wondering who's that consultant stepping out of the limo in front of HQ - and want a peek at the philosophy you'll soon be hearing - here's a guide to the likely suspects.
Pedigree: Professor, Marshall School of Business, University of Southern California
Education: PhD, economics and social science, MIT
Speaking Fee: Rarely accepts speaking engagements
Shtick: Leadership, leadership, leadership
Bio: Distinguished Professor of Business Administration at the University of Southern California and founding chairman of USC's Leadership Institute, Bennis has written 27 books, including On Becoming a Leader (which was translated into 22 languages). Although Bennis has never craved the limelight, the advisor to four U.S. presidents has emerged as an intellectual heavyweight. His books examine the qualities that make a great executive; vision, purpose, and a point of view are all central themes. But he also points out that managers must recognize their limitations and focus on only the most essential tasks.
