Power Types

Power types are the sources of influence a leader can draw upon, including expert, reward, legitimate, referent, and coercive power, as defined by French and Raven.

Explanation

French and Raven identified five bases of power that leaders use to influence others. Expert power comes from specialized knowledge or skills. Reward power comes from the ability to provide incentives. Legitimate power comes from formal authority or position. Referent power comes from personal charisma and the respect others have for the leader. Coercive power comes from the ability to punish or create negative consequences.

PMI considers expert and referent power the most effective forms of influence for project managers. Expert power builds credibility through demonstrated competence, while referent power builds loyalty through personal qualities and relationships. These forms of power create voluntary compliance and genuine engagement. Legitimate power is necessary but limited, as formal authority alone does not inspire people.

Coercive power is considered the least effective and most damaging form of power. Using threats and punishment destroys trust, reduces morale, and creates a fear-based environment. Reward power is effective in the short term but can lead to transactional relationships. The best project managers combine expert and referent power as their primary influence strategies.
