the best alternative to a negotiated agreement or BATNA (no deal option) refers to the most advantageous alternative course of action a party can take if negotiations fail and an agreement cannot be reached

BATNA is the key focus and the driving force behind a successful negotiator. A party should generally not accept a worse resolution than its BATNA.

BATNA of the other party determines their negotiating power.
