Fashions in business thinking change abruptly. The way we think about leadership, for instance, has shifted radically from the genius of great entrepreneurs like Rockefeller, Carnegie and Ford, through leadership as a science, leadership that releases human potential, the leader as strategist and warrior, customer champion, globalist and shareholder advocate, to, more recently, leadership as stewardship of the environment.

At the end of each section there is a summary of the key dilemmas that tend to emerge from the particular function.
