In what way must a good leader approach the four different leadership styles?

Horitative leader mobilizes the team toward a common vision and focuses on end goals, leaving the means up to each individual. If this style were summed up in one phrase, it would be "Come with me." The authoritative style works best when the team needs a new vision because circumstances have changed, or when explicit guidance is not required. Authoritative leaders inspire an entrepreneurial spirit and vibrant enthusiasm for the mission. It is not the best fit when the leader is working with a team of experts who know more than him or her.
