Plan produced by doctor getting behind (5)
I believe the answer is:
draft
'plan' is the definition.
(I know that draft is a more specific form of the action plan)
'doctor getting behind' is the wordplay.
'doctor' becomes 'Dr' (abbreviation).
'getting' is a charade indicator (letters next to each other).
'behind' becomes 'aft' (aft means towards or at the end of a ship).
'dr'+'aft'='DRAFT'
'produced by' is the link.
(Other definitions for draft that I've seen before include "Preliminary drawing" , "Bank payment order" , "Preliminary text or plan" , "A money order for US conscription" , "Formulate" .)
