Power, like authority, is a means of exercising influence on the behavior of people. But power is stronger than influence. Influence is a psychological force while power is a personal force that enables a person to change the behavior of others. Authority is the means to exert influence.
Power is an important means to enforce obedience to the rules, regulations and decisions of the organization. Power may be derived on personal or institutional bases. The use of power may affect the behavior of people in the desired manner. However, it does not necessarily imply that the people are in agreement with the exercise of power that a person is dependent upon another, he or she is subject to the other person’s power.
