In negotiation theory, the best alternative to a negotiated agreement (BATNA) is the most favorable and independent course of action a party can take if negotiations fail, aligning with their interests in the absence of a deal or an agreement. BATNA serves as an evaluative standard and a driving force behind effective negotiation strategy. A party should also consider the impact of the worst alternative to a negotiated agreement (WATNA), and care must be taken to ensure that deals are accurately valued. This includes consideration of factors such as the value of ongoing relationships, the time value of money, and the likelihood that the other party will fulfill their commitments.
