Stick with point developed - that's common sense (8)

Ross

I believe the answer is:

gumption

'common sense' is the definition.
('gumption' can be a synonym of 'common sense')

'stick with point developed' is the wordplay.
'stick' becomes 'gum' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'developed' is an anagram indicator.
'point' is an anagram of 'ption'.
'gum'+'ption'='GUMPTION'

'that's' is the link.

(Other definitions for gumption that I've seen before include "Courage needed!" , "Informal common sense or initiative" , "To impugn (anag) - common sense" , "Sense; courage" , "Shrewdness, common-sense" .)

I've seen this clue in The Telegraph.
