Negotiation strategies are planned approaches to reaching agreement, from hard positional bargaining to collaborative problem-solving. Three tools anchor most of them: your BATNA (best alternative to a negotiated agreement), your WATNA (worst alternative) and the ZOPA (zone of possible agreement). BATNA comes from Roger Fisher and William Ury’s Getting to Yes (first published 1981), developed at the Harvard Program on Negotiation.
List what happens if there is no deal, then pick the best (BATNA) and the worst (WATNA). Improve the BATNA before you sit down.
02
Estimate theirs
Work out the other side's likely alternatives. The ZOPA exists only where both walk-away points overlap.
03
Trade on interests
Ask why each side wants what it asks for. Different priorities across several issues create room for trades that help both.
04
Decide against the BATNA
Compare every final offer with your best alternative, not with your opening hopes.

AI agents that negotiate
Large language models now bargain with each other. In an international competition run by MIT researchers, people wrote prompts for AI negotiating agents that then negotiated with one another (Vaccaro et al., 2025). Warmth was linked to better outcomes overall, while dominant agents were better at claiming value.
Meta’s Cicero reached human-level play in Diplomacy, a game built on negotiation in natural language (Bakhtin et al., 2022). It worked by inferring other players’ beliefs and intentions from conversation and planning around them.
Retailers have started using software agents for routine supplier talks. Pactum, a vendor, says Walmart used its negotiation agent to renegotiate payment terms with suppliers; those results are vendor-reported.
Knowing your BATNA against a machine
When the other side is an agent that never tires, preparation matters more. A clear walk-away point stops you from drifting into concessions over a long exchange.
Negotiation tools compared
BATNA
Question it answersWhat do I do if we don't agree?
Typical mistakeNot improving it before talks start
WATNA
Question it answersHow bad could no deal get?
Typical mistakeIgnoring it and overrating your position
ZOPA
Question it answersIs there any deal both sides can accept?
Typical mistakeAssuming one exists without checking
Interests over positions
Question it answersWhy does each side want this?
Typical mistakeHaggling over one number only
Anchoring
Question it answersWho sets the first reference point?
Typical mistakeLetting an extreme first offer frame the talk
How to use it
Write down your BATNA and WATNA before the first meeting.
Take one concrete step to improve your BATNA, such as getting a second quote.
Estimate the other side's walk-away point and check whether a ZOPA exists.
Put several issues on the table (price, timing, terms) so you can trade between them.
If an AI agent negotiates for you, give it explicit limits and a walk-away rule.
The Business Engineer lens
As software agents start to buy, sell and renegotiate terms, bargaining power shifts to whoever has better alternatives and better data on the other side. The Business Engineer treats negotiation leverage as a structural question, not a question of charm.
In negotiation theory, BATNA stands for “Best Alternative To a Negotiated Agreement,” and it’s one of the key tenets of negotiation theory. Indeed, it describes the best course of action a party can take if negotiations fail to reach an agreement. This simple strategy can help improve the negotiation as each party is (in theory) willing to take the best course of action, as otherwise, an agreement won’t be reached.
In negotiation, WATNA stands for “worst alternative to a negotiated agreement,” representing one of several alternative options if a resolution cannot be reached. This is a useful technique to help understand what might be a negotiation outcome, that even if negative is still better than a WATNA, making the deal still feasible.
The ZOPA (zone of possible agreement) describes an area in which two negotiation parties may find common ground. Indeed, ZOPA is critical to explore the deals where the parties get a mutually beneficial outcome to prevent the risk of a win-lose, or lose-win scenario. And therefore get to the point of a win-win negotiation outcome.
Win-win negotiations first rose to prominence during the 1980s, thanks in part to books like Roger Fisher, William Ury, and Bruce Pattonโs bestseller Getting to Yes: Negotiating Agreement Without Giving In. Having said that, there was also a shifting mindset at the time as negotiators saw win-win negotiations as preferable to the then-dominant win-lose approach. A win-win negotiation is a negotiation outcome resulting in a mutually acceptable and beneficial deal for all involved parties.
A negotiation where one or both parties are unprepared can be disastrous. At best, the negotiation devolves into a loose and unfocused conversation. In the worst-case scenario, however, a negotiation can turn into an adversarial confrontation. The RADPAC model is a basic negotiation framework used in business to reach a favorable outcome for two or more parties.
Key Highlights
BATNA: Best Alternative To a Negotiated Agreement is the best course of action a party can take if negotiations fail to reach an agreement. It helps improve negotiations by ensuring each party has a viable alternative if an agreement cannot be reached.
WATNA: Worst Alternative To a Negotiated Agreement represents one of several alternative options if a resolution cannot be reached. Understanding the WATNA helps assess the feasibility of a deal, even if the outcome is negative.
ZOPA: Zone of Possible Agreement is the area where two negotiating parties can find common ground. Exploring the ZOPA is essential to achieve mutually beneficial outcomes and avoid win-lose or lose-win scenarios, aiming for a win-win negotiation.
Win-Win Negotiation: A negotiation outcome that results in a mutually acceptable and beneficial deal for all parties involved. It gained prominence in the 1980s as an alternative to the win-lose approach, emphasizing cooperation and mutual gains.
RADPAC Model: A negotiation framework used in business to reach a favorable outcome for two or more parties. Being prepared with the RADPAC model helps prevent unfocused and adversarial confrontations during negotiations.
BATNA (Best Alternative To a Negotiated Agreement)
DescriptionRepresents the best course of action if negotiations fail.
When to UseWhen entering a negotiation, it is essential to have a clear understanding of your BATNA, as it guides your negotiation strategy and helps you assess the value of potential agreements. It is also crucial to consider the other party’s BATNA.
AdvantagesEmpowers negotiators by providing a fallback option and preventing them from accepting unfavorable agreements. Enhances negotiation preparedness and strategic decision-making.
DrawbacksRequires careful assessment and may not always result in an optimal outcome. Parties may overestimate their BATNA’s strength.
WATNA (Worst Alternative To a Negotiated Agreement)
DescriptionRepresents the worst possible outcome if a resolution cannot be reached.
When to UseWhen evaluating the potential consequences of a failed negotiation. Understanding the WATNA helps negotiators assess the risks and consequences of not reaching an agreement.
AdvantagesProvides a clear understanding of the potential negative outcomes of a negotiation, motivating parties to seek mutually beneficial agreements. Helps negotiators set boundaries and prioritize deal terms.
DrawbacksFocusing solely on WATNA may lead to overly cautious or rigid negotiation approaches, hindering the exploration of creative solutions. Parties may have different perceptions of their respective WATNAs.
ZOPA (Zone of Possible Agreement)
DescriptionDescribes the space where mutually beneficial agreements can be reached.
When to UseDuring negotiations, ZOPA helps parties identify areas of common ground and explore potential agreements that benefit all parties. It is crucial to determine if a ZOPA exists before proceeding with negotiations.
AdvantagesFacilitates win-win negotiations by guiding parties toward mutually beneficial solutions. Prevents win-lose or lose-win scenarios by highlighting overlapping interests. Enhances the chances of reaching satisfactory agreements.
DrawbacksIdentifying the ZOPA may require effective communication and information sharing, which can be challenging. Parties may have differing perceptions of the ZOPA’s boundaries.
Win-Win Negotiation
DescriptionFocuses on achieving mutually acceptable and beneficial outcomes for all parties.
When to UseWhen parties aim to collaborate, create value, and preserve relationships in negotiations. Win-win negotiation is preferable when long-term partnerships, goodwill, and reputations are at stake.
AdvantagesPromotes positive and cooperative negotiation dynamics, fostering trust and long-term relationships. Encourages creative problem-solving and value creation. Enhances overall satisfaction among negotiating parties.
DrawbacksMay require more time and effort to explore and create value, which can be challenging in time-sensitive or competitive situations. Achieving a true win-win outcome may not always be feasible.
RADPAC Model
DescriptionA negotiation framework used to reach favorable outcomes for multiple parties.
When to UseIn any negotiation where one or more parties need guidance to ensure a structured and favorable outcome. The RADPAC model can be especially useful when parties are unprepared, and the negotiation risks becoming unproductive.
AdvantagesProvides a structured approach to negotiation, guiding parties through key stages (Research, Analysis, Design, Proposal, Agreement, Close). Enhances negotiation preparedness and focus. Helps prevent adversarial confrontations and unproductive discussions.
DrawbacksThe model’s effectiveness may vary based on the complexity and nature of the negotiation. It may require adaptability to suit different negotiation contexts. Parties may still encounter challenges in reaching agreement, depending on their positions and interests.
