Negotiations: One-Text Procedure

(From "Getting to Yes" book by Roger Fisher and William L. Ury)

Third party required.

1. collect true interests of the negotiation parties on one sheet of paper
2. prepare draft proposal and present to parties for criticism
3. update proposal due to received feedback
4. repeat from step 2 till no more critical ideas received

This gets to the point where all negotiation parties can say Yes or No.
