Authoritarian leadership is a leadership style in which the leader dictates policies and procedures without account team members' opinions. This style can be beneficial in certain circumstances, for example when decisions need to be made quickly and also allows group members to focus on their own task without concerning about making decisions. In the other hand, if the leader abuses their power, it can lead to resentment from group members. Democratic leadership is the opposite of authoritarian leadership. Democratic leadership is where the team members are included in the making process of the decision but the team leader has the final word. Team leaders encourage members to be creative and they often make members get engaged in projects. This leadership style is not very effective if a quick decision needs to be made. Democratic leadership is more effective when team members are skilled and want to share their knowledge.
Scenario.
If for instance, police force is running an operation to arrest someone, it is beneficial and effective if authoritarian leadership is used. In the other hand, democratic leadership would not be useful and could bring many consequences because it is not the type of leadership to be used when decisions need to be made quickly. .
Transformational vs. Transactional.
Transformational is a type of leadership style that can inspire positive changes in those who follow. Leaders are usually enthusiastic, energetic and passionate. Not only are these leaders concerned and involved but also they are focused on helping every team member to succeed and it leads to high productivity and engagement from team members. On the other hand, transactional leadership is a style that focuses on short-term tasks and where team members agree to obey their leader when they take the job. The leader has the right to 'punish' team members if their work does not meet an appropriate standard and also members get rewarded if the work meets that standard.
