Oversee, supervise (11)
I believe the answer is:
superintend
This clue is a double definition.
'oversee' is the first definition.
(I know that oversee can be written as superintend)
'supervise' is the second definition.
(I know that supervise can be written as superintend)
(Other definitions for superintend that I've seen before include "monitor" , "run" , "Oversee" , "Be responsible for the management of" , "Supervise" .)
