One of the key roles of the leader is to model failure. If the leader models failure properly, he leads the way for his own people to fail successfully. The leader who models failure can demonstrate how one can admit their mistakes, and incorporate them into the larger cycle of a success. It is important that the leader does not maintain the illusion that he always succeeds. No one always succeeds. He must make it possible for his team to fail in a way that delivers a positive outcome.
