Series of planned actions to achieve a goal (8)
I believe the answer is:
campaign
'series of planned actions to achieve a goal' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for campaign that I've seen before include "Series of operations, military or advertising" , "Series of actions toward a particular end" , "lobby" , "Am pacing about in series of planned activities" , "Military operation" .)
