Final answer:
Authoritarian leadership on Blake and Mouton's leadership grid is defined as Authority-compliance management, focusing on tasks with minimal team member input and can lead to alienation if overused.
Step-by-step explanation:
According to Blake and Mouton's leadership grid, authoritarian leadership reflects Authority-compliance management (D). This is characterized by leaders who issue orders and assign tasks with little to no feedback from group members, focusing primarily on task completion and less on the needs of the team members.
Authoritarian leaders are seen as instrumental leaders with a strong focus on meeting goals, which can be advantageous in situations requiring quick decisions or specialized expertise. However, this leadership style can risk alienating team members if used excessively. In Blake and Mouton's leadership grid, the managerial grid model identifies different leadership styles based on two behavioral dimensions: concern for people and concern for production. The "authority-compliance management" style, also known as "9,1" style on the grid, is characterized by a high concern for production (task) and a low concern for people. This style is often associated with an authoritarian or autocratic leadership approach where the leader emphasizes efficiency and results over the well-being and satisfaction of the team.
