Continue this process until the team is satisfied with the results of the leadership appraisal process. While the leader's seniors determine if goals and objectives were met, only the leader's subordinates can determine if their senior is a leader. Determining if a person has leadership skills is based upon the willingness of people to follow that person. If I tell you to do something, that merely makes me your boss. My senior might think I am a leader because I am able to get things done, but having the authority to order people around does not qualify a person as a leader.
Peers are also part of the evaluation process because they often work together as teams.
For example, Bill Walsh, Tom Landry and Chuck Knoll each won several Super Bowls, but they also had the worst first-season records of any coaches in the National Football League's history. Also, over half of the Fortune 500 CEOs had a C average in college, yet they went on to manage some of the best organizations in America. Fred Astaire failed his first screen test. It would have been a huge loss if the potential was not recognized in these great individuals. Keep the goals focused on improving needed competencies.
