In Govt and other R&D organisations 'powers' are outlined 'status-wise' like Power of Director, Asst. Director, Dy. Director, Head of the Department, Controller, Dvn. Heads, Officers, Asst. Officers.......which thus mean that they are 'Granted and Given'. By this them powers are 'taken' into the respective hands caprisoning individual chairs.
