How do authority and power differ:,”authority is a right, power refers to an individual’s capacity to influence decisions. It is a three dimensional concept, including not only functional and hierarchical dimensions, but also centrality. Centrality is the distance from the power core. It suggests that the higher you move in the organization, the closer to the power core. And, it is not necessary to have authority in order to wield power. Power come from five sources: coercive, reward, legitimate
expert and referent.”
