Practices that may help

1. ZOPA: The Zone of Possible Agreement
   ZOPA (Zone of Possible Agreement) is the range of outcomes that both parties would prefer to reaching no deal at all. If one party’s minimum acceptable term is better than the other’s maximum acceptable, a ZOPA exists and a deal is theoretically reachable. If there is no overlap, no mutually acceptable deal is possible and negotiators are wasting time pursuing one.
2. Propose a post-settlement settlement to optimize an agreed deal
   After reaching a deal, offer to see if you can both do better — many agreements leave joint value on the table.

3. Test whether a ZOPA exists before investing further
   When you suspect there may be no overlap, surface the zone gap early rather than investing time in an impossible deal.

4. Expand the ZOPA by adding issues to the negotiation
   When you’re stuck on a single issue, adding more issues often creates room for trades that satisfy both sides.
