Principled Negotiation (Fisher & Ury — "Getting to Yes") is the PMI-preferred negotiation framework. It focuses on interests, not positions, and seeks mutual gain.

4 principles of principled negotiation:

  1. Separate people from the problem: Attack the issue, not the person
  2. Focus on interests, not positions: Ask "Why?" not just "What?"
  3. Invent options for mutual gain: Brainstorm before committing
  4. Use objective criteria: Market rates, standards, precedents

BATNA (Best Alternative to a Negotiated Agreement) — know your walk-away point before negotiating.

🇻🇳 Tiếng Việt

Đàm phán theo nguyên tắc (Fisher & Ury — "Getting to Yes") là framework đàm phán PMI ưu tiên. Tập trung vào lợi ích, không phải lập trường, và tìm kiếm lợi ích chung.

4 nguyên tắc của đàm phán theo nguyên tắc:

  1. Tách người ra khỏi vấn đề: Tấn công vấn đề, không phải người
  2. Tập trung vào lợi ích, không phải lập trường: Hỏi "Tại sao?" không chỉ "Cái gì?"
  3. Tạo ra các lựa chọn cho lợi ích chung: Brainstorm trước khi cam kết
  4. Sử dụng tiêu chí khách quan: Giá thị trường, tiêu chuẩn, tiền lệ

BATNA — Biết điểm bỏ cuộc của bạn trước khi đàm phán.

💼 Thực chiến / Scenario

🏢

FinTech Company X — Negotiating API SLA with Bank Partner

Tình huống: Trước khi go-live Project Alpha với Bank Partner A, cần negotiate SLA agreement. Partner muốn 99% uptime SLA (8.7 hours downtime/month). PM/CTO muốn 99.9% (52 phút/tháng) vì platform lending cần high availability.

Principled negotiation approach:

Tách người ra khỏi vấn đề: "Chúng ta đều muốn partnership thành công. Vấn đề là SLA levels — hãy tìm solution thoả mãn cả hai."

Focus on interests: Hỏi partner: "Tại sao 99% là giới hạn?" → Họ lo về maintenance windows và on-call costs. Không phải họ không muốn reliable service — họ sợ commitment quá cao.

Options for mutual gain: Propose tiered SLA: 99.9% for business hours, 99% for off-peak. Agree on maintenance windows (Sundays 2-6am). Auto-notification when downtime planned. Penalty structure đơn giản.

Kết quả: Agreement đạt được: 99.5% overall, 99.9% business hours. Cả hai sides có win. Đây là principled negotiation trong action.

✏️ Practice Questions

Question 1
During contract negotiation with a vendor, both parties are stuck on price. The vendor won't go below $100K, and your budget is $80K. According to principled negotiation, what should you do FIRST?
  • A. Walk away from the negotiation
  • B. Explore each party's interests to understand why these positions exist, and look for creative options
  • C. Split the difference and agree on $90K
  • D. Bring in a mediator to resolve the deadlock
✅ Answer: B — Principled negotiation says: focus on interests, not positions. Explore WHY the vendor needs $100K (cash flow? cost structure?) and WHY $80K is your limit (budget cap? other constraints?). Creative options might emerge: phased payments, reduced scope for $80K, performance-based bonuses, etc. Splitting the difference (C) is compromise not principled negotiation. Walking away (A) should come after options are exhausted.
Question 2
During a negotiation with a vendor, the vendor refuses to budge on price but offers better support terms. According to principled negotiation, what should the PM consider?
  • A. Walk away since price is fixed
  • B. Explore whether the support terms represent value equivalent to the price gap (focus on interests, not positions)
  • C. Accept the higher price since the vendor is being firm
  • D. Bring in legal to enforce the original price
✅ Answer: B — Fisher & Ury: focus on interests (value) not positions (price). The vendor's "better support terms" may represent real value — e.g., reduced operational cost, faster issue resolution, or risk reduction — that closes the gap between the $price positions. A PM applying principled negotiation looks beyond the stated position to the underlying interest and evaluates the total value of the package.
Question 3
A PM is negotiating resource allocation with a functional manager. The functional manager insists they cannot release their developer for more than 2 days per week. The PM needs 4 days. What is the BEST first step?
  • A. Escalate to the sponsor to force the manager to comply
  • B. Identify the functional manager's underlying interests (why only 2 days?) and explore options that satisfy both
  • C. Accept 2 days and adjust the project schedule
  • D. Find an external contractor immediately
✅ Answer: B — Understand interests first before escalating or accepting. The functional manager's "2 days" is a position — their interest may be: protecting a key resource for another critical deliverable, concern about context-switching, or BAU commitments. By exploring the "why," the PM may uncover options: staggered allocation, role split, time-boxing the high-need weeks, or solving the functional manager's other constraint. Escalating immediately (A) damages the relationship and may not be needed.

Sample Claude Prompts

Negotiation preparation — BATNA analysis I'm preparing to negotiate [what — contract / resources / timeline / budget / scope]. My position: [what I want] My BATNA (Best Alternative To Negotiated Agreement): [what I do if negotiation fails] Their likely position: [what the other party wants] Their likely BATNA: [what they do if this fails — my estimate] Zone of Possible Agreement: [where I think overlap exists] Constraints I can't move on: [hard limits] Help me: 1. Map the negotiation zone (ZOPA analysis) 2. Identify 3 tradeable variables (things I can give to get what I need most) 3. Develop my opening position and first concession plan 4. Anticipate their top 3 objections and prepare responses 5. Define my walk-away point and how I'll communicate it without burning the relationship
Vendor/contractor negotiation I'm negotiating a contract with [vendor / contractor type]. Deliverable: [what they'll deliver] My budget: [range — don't reveal exact number to them] Their quoted price: [their opening offer] Market rate (if known): [benchmark] Timeline flexibility: [fixed / flexible] Quality requirements: [non-negotiables] Relationship: [new vendor / existing partner] Draft a negotiation strategy including: 1. Counter-offer with justification (market data, scope adjustments) 2. 3 creative value exchanges (not just price reduction) 3. Contract terms I should push for (payment milestone, IP, SLA) 4. Red flags to watch for in their response 5. Script for the opening 2 minutes of the negotiation call
Internal resource negotiation I need to negotiate for [team members / budget / timeline extension] with [functional manager / sponsor / PMO]. What I need: [specific resource request] Business justification: [why the project needs this] Their likely concerns: [budget / other priorities / precedent] What I can offer in return: [flexibility, reporting, phasing] My leverage: [project priority, sponsor support, risk of not having it] Help me build a persuasion case with: 1. Data-driven justification (ROI or risk cost of not approving) 2. Options I can present (full ask / scaled ask / alternative) 3. Pre-wiring strategy (who to talk to before the formal ask) 4. The one-page proposal I'd send ahead of the meeting
