Organise with dash? (3)
I believe the answer is:
run
I believe this is a double definition.
'organise' is the first definition.
(both can mean to lead or be in charge of)
'dash?' is the second definition.
(dashing is a kind of running)
'with' acts as a link.
(Other definitions for run that I've seen before include "Trot" , "Control" , "stand" , "A single" , "Flow; smuggle (goods)" .)
