Ronald Heifetz has been a professor of public leadership at Harvard's Kennedy School for three decades, teaching classes that have included aspiring business leaders and budding heads of state. Each year, he says, the students start his course thinking they'll learn the answer to one question:

Heifetz says that whole approach is wrong.
"The dominant view of leadership is that the leader has the vision and the rest is a sales problem," he says.
