Effective leadership = vision, passion, direction.
Under this type of leadership teams thrive. BUT what happens when there is a void, another leader doesn't perform, or leaves? Typically, someone who is not supposed to lead, or does not have the skills to lead, tries to step into leadership. Dissension arises. And if something is not done quickly, chaos spreads.
To stabilize your team, you must act fast. To keep peace and momentum, you either have to place the person who you have been training into that leadership position, or, if you have trained no one, then you must assume temporary leadership yourself.
When you do, peace will again reign, direction will be pursued and effectiveness will be maintained.
