Apply principled negotiation using BATNA, ZOPA, and the Harvard method to prepare for and conduct negotiations. Use this skill when the user needs to prepare for a negotiation, evaluate their bargaining position, design win-win solutions, or handle difficult negotiation situations — even if they say 'how do I negotiate this deal', 'what's my leverage', 'they won't budge on price', or 'help me prepare for this meeting'.
IRON LAW: Know Your BATNA Before Entering Any Negotiation
BATNA (Best Alternative To a Negotiated Agreement) is your walkaway power.
If you don't know your BATNA, you don't know when to walk away — and
you'll either accept a bad deal or reject a good one.
Calculate your BATNA and the other side's BATNA before the negotiation starts.
| Concept | Definition |
|---|---|
| BATNA | Your best option if negotiation fails — your walkaway point |
| ZOPA | Zone of Possible Agreement — overlap between both parties' acceptable ranges |
| Reservation price | The worst deal you'd accept (set by your BATNA) |
| The best deal you realistically hope for |
Separate people from the problem: Address emotions and relationship separately from substantive issues. Be hard on the problem, soft on the person.
Focus on interests, not positions: Positions are what people SAY they want. Interests are WHY they want it. "I want $100K salary" (position) vs "I need financial security and recognition of my expertise" (interests).
Invent options for mutual gain: Expand the pie before dividing it. Brainstorm solutions that satisfy both parties' interests.
Use objective criteria: Base agreements on fair standards (market rates, precedent, expert opinion) rather than who has more power.
| Situation | Tactic |
|---|---|
| They won't move | Ask "why" to uncover underlying interests |
| They use threats | Acknowledge the threat without reacting; redirect to interests |
| They anchor extremely | Counter-anchor with your own extreme (but justifiable) number |
| Deadlock | Take a break, change the negotiator, or introduce a mediator |
| They say "take it or leave it" | Test it — they usually don't mean it. Offer a concession and ask for one back |

|---------|-----|-------------|
| BATNA | {your alternative} | {their alternative, estimated} |
| Reservation price | {your walkaway} | {their walkaway, estimated} |
| Aspiration price | {your ideal} | {their ideal, estimated} |
| ZOPA | {overlap range, if any} |
## Interests (not positions)
| Your Interests (priority) | Their Interests (estimated) |
