What criteria can be used to determine if someone is an effective leader or no?

Effective leaders can be assessed based on several criteria, including their ability to communicate clearly and inspire others, their decision-making skills, and their capacity for empathy and emotional intelligence. Additionally, successful leaders often demonstrate adaptability in the face of challenges and a track record of achieving goals while fostering a positive team culture. Feedback from team members and stakeholders can also provide valuable insights into a leader's effectiveness.
