Devolution of power refers to the transfer of power and authority from a central government to regional or local governments. This transfer of power is often done to give regional or local governments more autonomy and decision-making power over certain issues that affect their communities. Devolution can also involve transferring power to administrative or quasi-governmental bodies, such as public utilities or development agencies.
Delegation of power, on the other hand, refers to the transfer of authority from one person or group to another within an organization or government. This transfer of authority is often done to allow someone else to handle specific tasks or responsibilities. Delegation can occur at any level within an organization, from top management down to front-line employees. The person or group delegating the power retains ultimate authority, but they entrust others with the ability to make decisions and take action within a certain scope.
