What its author says it does
Copied from the file, not written here
Prepares for a negotiation using the Best Alternative to a Negotiated Agreement (BATNA), reservation price, Zone of Possible Agreement (ZOPA), multi-issue trade design, anchoring tactics, and concession plans, then simulates the counterparty and produces a play-by-play strategy. Use before commercial negotiations, Mergers and Acquisitions (M&A) talks, vendor or partnership deals, internal resource negotiations, hiring offers, or any multi-issue bargaining where preparation outranks instinct.

Negotiation Strategist
Preparation collapses the role of luck. This skill is the preparation.
What this skill is
A pre-negotiation workflow that codifies your interests, your Best Alternative to a Negotiated Agreement (BATNA), your reservation price, the likely Zone of Possible Agreement (ZOPA), the issues available for multi-issue trades, an anchoring plan, a concession schedule, and a simulated counterparty profile. Outputs a play-by-play with the opening move, anticipated responses, and the trigger conditions to walk away.
What it solves
- Walking into negotiations with a target price but no BATNA
- Single-issue bargaining when multi-issue trades create value
- Anchoring badly (or being anchored) because the open wasn't prepared
- Conceding without getting something in return
- Confusing positions with interests - and missing the integrative deal
When to invoke
- Commercial contract negotiations (vendor, customer, partner)
- Mergers and Acquisitions (M&A) or financing term-sheet talks
- Internal negotiations (budget, headcount, scope, deadlines)
- Hiring offer or counter-offer
- Salary or compensation review
- Multi-party coalition deals
Phase 1: Identify interests, not just positions
For each side, list:
- Stated positions - what they say they want (e.g., "$50 per seat per month")
- Underlying interests - why they want it (e.g., "hit Q4 budget; show win to Chief Financial Officer (CFO); reduce vendor sprawl")
- Constraints - what they cannot do (regulatory, internal policy, signed precedent)
Interests outnumber positions and overlap more than positions do. The negotiation moves when you find an interest-level alignment.
Phase 2: Compute BATNA and reservation price
Best Alternative to a Negotiated Agreement (BATNA) is your fallback if this deal falls through:
- List actual alternatives, not hypothetical ones
- Quantify each (revenue, cost, time)
- Pick the best - that's your BATNA
Reservation price is the worst deal you'd still accept (one notch better than BATNA). Below this, you walk.
Never enter a negotiation without a written BATNA and reservation price. Improve your BATNA before negotiating if you can - it's the single highest-leverage preparation move.
Phase 3: Estimate the counterparty's BATNA and reservation
Use whatever you have:
- Their public alternatives (Request for Proposal (RFP) responses, vendor list, public M&A history)
- Internal signals (urgency, end-of-quarter pressure, regulatory timelines)
- Past behavior (have they walked before? at what level?)
If your reservation price ≤ their reservation price, there is a Zone of Possible Agreement (ZOPA). Negotiation happens inside it. If no ZOPA, the deal isn't viable - change the issues.
Phase 4: Expand to multi-issue trades
Single-issue negotiation is always distributive (zero-sum). Multi-issue negotiation can be integrative (value-creating) by trading across issues each side values differently.
For each side, list all issues and rank by importance (1 = most, n = least):
| Issue | Your priority | Counterparty's priority | Trade potential |
|---|---|---|---|
| Price | 1 | 1 | Distributive |
| Payment terms | 5 | 2 | High - they care more |
| Contract length | 2 | 5 | High - you care more |
| Exclusivity | 3 | 4 | Modest |
| Service Level Agreement (SLA) | 4 | 3 | Modest |
The high-trade-potential issues are where value is created. Concede on what they value, get what you value.
Phase 5: Anchoring and opening move
The opener defines the range. Anchoring rules:
- Open ambitious but justifiable - well outside the midpoint, with a rationale (precedent, comparables, internal cost)
- The rationale matters more than the number - "industry comparables say $X"
- If they open first, don't counter-anchor immediately - ask for the rationale, then reframe
Decide: do you go first, or wait? Go first if you have better information about ZOPA. Wait if you don't.
Phase 6: Concession plan
Plan concessions before the meeting. Rules:
- Make smaller concessions over time, not larger ones - signals you're approaching your reservation
- Never concede unilaterally - every concession asks for one back
- Use conditional concessions: "If you can do X, I can do Y"
- Bundle, don't unbundle - concede multiple low-priority items together
| Round | Your move | Counter-ask | Walk-away trigger |
|---|---|---|---|
| 1 | Open at $X, 36 months, SLA Y | - | They counter below $W |
| 2 | $X-10, 36 months, SLA Y | Add Z | Below reservation |
| 3 | $X-15, 24 months, SLA Y | Approval timing | etc. |
Phase 7: Tactical playbook
Common tactics - know them, plan for them:
- Good cop / bad cop - name it to neutralize
- Higher authority - "I need to check with my boss" delays; counter by asking for the decision-maker
- Deadline pressure - verify the deadline is real; if artificial, ignore
- Take-it-or-leave-it - call the bluff if BATNA supports it
- Nibble - small late asks; refuse all nibbles or reopen the package
- Silence - let the silence sit; the next speaker often concedes
Phase 8: Simulate the counterparty
Pre-game with a colleague playing the counterparty. Specifically:
- Run the opening move and three rounds
- Pressure-test your concession plan
- Identify the one question that would derail you and prepare an answer
- Identify your tells (impatience, over-justification) and plan around them
Output
- Interests and positions for both sides
- BATNA and reservation price for both sides
- ZOPA verdict (exists, doesn't, or depends on issue expansion)
- Multi-issue trade matrix
- Anchoring plan with justified opener
- Concession schedule with conditional asks
- Tactical playbook with anticipated tactics named
- Walk-away triggers - explicit
- Post-negotiation review template
Operating rules
Always
- Define BATNA and reservation price before the meeting
- Convert positions into interests
- Expand to multi-issue when possible
- Make conditional concessions (never unilateral)
- Simulate the counterparty before the real conversation
Never
- Open with a midpoint number
- Negotiate against yourself with successive concessions
- Reveal your reservation price
- Treat their first offer as their reservation price
- Confuse a tactic ("higher authority") with a real constraint
