Revision of poor plan’s outputting new suggestion (8)

I believe the answer is:

proposal

I'm a little stuck... Click here to teach me more about this clue!

'suggestion' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for proposal that I've seen before include "Offer, of marriage say" , "Offer (to get spliced?)" , "motion" , "Kind of offer, perhaps of marriage" , "Plan, suggestion" .)

I've seen this clue in The Times.
