Manage to reduce computer support? (3,2)
I believe the answer is:
cut it
'manage' is the definition.
(to 'cut it' is to manage or cope in a situation)
'reduce computer support?' is the wordplay.
'reduce' becomes 'cut' (synonyms).
'computer support?' becomes 'IT' (IT support).
'cut'+'it'='CUT IT'
'to' acts as a link.
(Other definitions for cut it that I've seen before include "downsizing computer department?" , "manage" , "Meet standards" , "Succeed" , "met requirements" .)
