Manage flow (3)
I believe the answer is:
run
I believe this clue is a double definition.
'manage' is the first definition.
(both can mean to organise)
'flow' is the second definition.

(Other definitions for run that I've seen before include "publish" , "Card sequence in suit" , "A point scored in cricket" , "Race; flee" , "Go swiftly - ladder" .)
