Fire, snowball, mask, movie: how leaders spark and sustain change.

What does it take for an average manager to become a highly effective leader? There are countless books, models, and formulas for success. But the truth is that leadership transformation is deeply dependent on circumstances. The key for those who seek it is to absorb the insights that can be drawn from the successful experiences of others. During their in-depth study of seven CEOs, Fuda and Badham uncovered seven interdependent metaphors, which they went on to test with more than 10,000 managers on four continents. The authors discuss four of those metaphors--fire, snowball, mask, and movie--here, in the context of individual managers' experiences.
