What is BATNA?

Definition

You're three hours into a contract negotiation when the other party offers terms you know are suboptimal. You want to push back, but there's a voice in your head: "What if they walk? What if this is the only deal available?" That fear (the fear of having no alternative) is precisely what weakens your position.

This is why BATNA matters.

BATNA stands for Best Alternative to a Negotiated Agreement. It's the most advantageous course of action you can take if the current negotiation fails. Your BATNA isn't hypothetical wishful thinking: it's a concrete, actionable plan that exists independent of this negotiation.

Developed by Roger Fisher and William Ury in their seminal work Getting to Yes, BATNA is the single most important factor determining your negotiation power. A strong BATNA means you can walk away confidently from a poor deal. A weak BATNA: or worse, the absence of one means you're negotiating from desperation.

Why BATNA Determines Negotiation Power

Your BATNA is your leverage. If the other party senses you have no alternative, they can push for increasingly favourable terms. If they know you have a strong BATNA, they're incentivised to offer competitive terms to keep you at the table.

Here's the critical distinction: your BATNA isn't about what you say you'll do if the deal fails. It's about what you've already prepared to do. The property director who has three other buyers interested doesn't just claim leverage (she has it. The consultant who's cultivated alternative clients doesn't bluff about walking away) he can actually do it.

Conversely, negotiating without a BATNA is negotiating from weakness. You'll accept suboptimal terms because "something is better than nothing." Except sometimes nothing (investing that time and energy elsewhere) would have been far better than a value-destroying deal.

Importantly, your BATNA changes your psychology. When you know you have a viable alternative, you're calmer, more patient, less desperate. This composure itself improves negotiation outcomes. Desperation is visible, and it invites exploitation.

Practical Application

Immediate technique: Before any high-stakes negotiation, write down your BATNA explicitly. What will you literally do if this negotiation fails? If you can't answer that question concretely, you don't have a BATNA you have hope. Develop a real alternative before entering the negotiation.

Common mistake to avoid: Confusing a BATNA with your reservation price (walk-away point) or your aspiration. Your BATNA is not "I hope to get £500K" or "I won't accept less than £400K." It's "If this fails, I will pursue this specific alternative deal that's worth £350K to me." That specificity is what gives BATNA its power.
