The document summarizes three leadership theories: 1. Managerial Grid Theory identifies five leadership styles based on concern for production and people. The optimal style is high concern for both. 2. Path-Goal Theory states that a leader's style should motivate employees by focusing on the task and environment. Directive, supportive, participative, and achievement-oriented styles should be used. 3. Contingency Theory says a leader's effectiveness depends on matching their style (task-oriented or relationship-oriented) to the situation based on relationships, task clarity, and authority. The LPC scale determines a leader's orientation.
