Series of actions to achieve a result (7)
I believe the answer is:
process
'series of actions to achieve a result' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for process that I've seen before include "Method of production" , "Use IT perhaps < to handle" , "move in train" , "Series of steps achieving a particular end" , "Method of operation" .)
