However, greatness in leadership demands balance among the four. This need for balance is clearly seen in relation to change. The leader's vision sets the course for the organization. The vision must be adjusted to accommodate the changed reality. The ethics factor will require the leader's sensitive treatment of his subordinates.
Courage allows the leader to confront the changed reality outside.
It is also supports the mobilization of change within. Experience also shows the need for balance among the factors. I once saw an organization suffer a leadership crisis. The problem was one of vision. The majority of the members felt that the leader's vision was faulty.
