A person on whom an individual or group confers the capacity to act on his or their behalf. The central idea of delegation is that the person who delegates passes authority or responsibility to the person who is delegated to carry out a task or assume a role: hence a delegate may also be a representative (see also representation). The relationship between the principal (who delegates) and the agent may be variously understood. For example, a delegate may be sent to a meeting only in order to report back to his or her principals, or may be sent with authority to bind his or her principals to a decision. Delegation thus involves the notions of authorization, accountability, and responsibility, but any specific act of delegation will contain particular applications of these ideas.
