Leadership involves the ability to bring about a desired change or action from or with others. It implies a kind of movement that invites others to follow leaders in their thinking, feeling, or action. A leader encourages people to act to benefit themselves and others. In other words, leaders are able to intervene in processes that are internal and external to an organization, agency, or other group because they have influence based on power. Leadership power is either attributed power or actual power .
Attributed power comes from the perception among others of the leader's ability to lead.
They simply believe in the leader's expertise and ability to guide. Consequently, they regard the leader with esteem. Actual power refers to a leader's access to resources needed to change conditions inside and outside the organization. Early theories regard leadership as an innate trait or characteristic with which only a few people are born. Today, it is considered a cluster of behaviors that can be learned.
