Pros
Charismatic leaders have the ability to sense the gap that exists between what an organization is delivering to its followers, and what the followers need from an organization. This allows the leader to create a vision of a future state that everyone believes will be better than today's environment.
The charismatic leader often articulates this vision using metaphors and stories in such a way that everyone can understand the vision. The followers see the leader as one that possesses the ability to visualize the future with clarity. The followers are also able to see how they fit into this future state, and believe it will be better than today.
Since followers can see themselves in this future vision, they support the goals of the organization and the leaders more readily. Rather than resorting to coercion, the charismatic leader builds trust among followers.
