For servant leadership theory, the leader prioritizes serving others and allows subordinates decision-making power. For adaptive leadership theory, the leader provides support during challenges and develops short-term solutions to ease organizational issues. The document suggests that as a new CEO, applying transformational and adaptive leadership styles could help the company succeed by establishing a compelling vision, empowering employees, addressing challenges, and strengthening adaptability.
