Staff meeting generates order (7)
I believe the answer is:
'order' is the definition.
(I know that mandate is a more specific form of the action order)
'staff meeting' is the wordplay.
'staff' becomes 'man' (as in staffing or manning a particular place).
'meeting' becomes 'date' (date is a kind of meeting).
'generates' acts as a link.
(Other definitions for mandate that I've seen before include "Decree" , "Authority conferred on a tandem" , "Authorization, official instruction" , "Authority to act" , "Give authority to" .)
