A businesslike programme (6)
I believe the answer is:
agenda
'programme' is the definition.
(I know that agenda is a type of programme)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for agenda that I've seen before include "To-do list" , "List of things to be done or discussed" , "Menu" , "List of items for committee to consider" , "Meet to discuss this" .)
