In The Leader's Code, Donovan Campbell espouses the servant-leadership model he learned in the military which relies on:
1. Mission: This is a broad purpose with a focus on the welfare of others. To develop a mission, the leader must understand that man is mortal and time is limited. The mission must be worthy and every action performed toward the mission must count. The mission must also be worthy of sacrifice.
2. Humility: A leader must know his or her strengths and weaknesses as well as those of the team. The humble leader is willing to self-assess, self-criticize, and listen and respond to criticism from throughout the organization. A humble leader is not afraid of exposing a weakness if it can ultimately make the team stronger.
3. Excellence: A good leader cultivates excellence for its own sake. Excellence does not refer to a positive outcome, but rather to doing the best job possible every day. This approach to excellence cultivates perseverance and hope in the leader and the team.
4. Kindness: A servant leader expresses the four components of kindness, which include feeling empathy for another's predicament, acting on that empathy, providing help regardless of perceived "worthiness,"
5. Discipline: A core component of character, discipline has both an ethical and practical side. It begins with a set of shared moral values that are upheld in all circumstances and ends with enforcing standards fairly and equitably, and, when necessary, delivering consequences.
6. Courage: In the business world, courage primarily refers to moral courage, which is speaking truth to power. Moral courage requires individuals to articulate their moral values, resolve to accept the consequences of upholding them, bear responsibility for failure, and admit their mistakes.
7. Wisdom: Wisdom brings all the virtues together. A wise leader must choose the correct action at the correct moment, accept the limits of control, and focuses on what can be changed. A wise leader does not worry about the future or cultivate contentment.
