Move to cut cost for routine (8)
I believe the answer is:
practice
'for routine' is the definition.
(I've seen this before)
'move to cut cost' is the wordplay.
'move' becomes 'act' (synonyms).
'to cut' is an insertion indicator (some letters cut their way into a word).
'cost' becomes 'price' (the cost or price of something).
'act' going inside 'price' is 'PRACTICE'.
(Other definitions for practice that I've seen before include "Doctor's premises" , "Exercise; professional business" , "The exercise of a profession" , "Habit - procedure" , "Learn by repetition" .)
