Authority refers to the legitimate right to direct others and make decisions. It flows downward through the organizational hierarchy from high-level managers to lower-level employees. There are three main theories that explain the emergence of authority: the formal theory which sees it flowing from top to bottom positions; the acceptance theory which views it as relying on subordinates' acceptance; and the competence theory which ties it to managers' qualifications. Authority is limited by legal, physical, economic, and biological factors. Responsibility is the obligation to perform assigned duties and flows upward. Accountability is the liability for authority used and also flows upward through reporting requirements. Delegation involves transferring authority to subordinates while maintaining accountability.
