Authority and Power

Meaning 

For an organisation to work efficiently and smoothly a formal authority system must be supplemented with informal power and influence. It has often been observed that managers use more than their official authority, to obtain cooperation from their subordinates. 

"Power" is the ability to exercise influence or control over others, even demands obedience. "Authority" on the other hand is the right to command and extract obedience from other. It comes from organisation and it allows the leader to use power. 

However. it is not necessary that one has authority before, exercising power. As a matter of fact, many a managers in Indian organisation find it difficult to exercise authority vested with them.
