Negotiation doesn't have to be a positional battle of wills where both sides start with extreme positions and gradually make minimal concessions. "Getting to Yes" introduces a revolutionary approach called principled negotiation which focuses on reaching mutually beneficial agreements based on objective criteria rather than power dynamics.
The fundamental insight of principled negotiation is that successful deals address underlying interests, not surface-level positions. By understanding what each party truly needs, negotiators can craft creative solutions that expand value by getting each side what they most need and build lasting business relationships.
The key point for salespeople is that it's often best to approach negotiation with a spirit of investigation, creativity, and collaboration.
The Four Elements of Principled Negotiation
Principled negotiation consists of four fundamental elements:
Separate the people from the problem: Disentangle relationship issues from substantive matters. Address people problems (perception, emotion, communication) directly by making emotions and perceptions explicit. "Try on" the other side's views and give them ownership in the process.
Focus on interests, not positions: Focusing on underlying interests reveals compatible solutions — ones that secure each side what they most need — that are impossible to discover when fixated on positions.
Invent options for mutual gain: Expand the pie before dividing it. Look for items of low cost to you but high value to them and vice versa so that you can trade. Brainstorm multiple options even with the other side and break problems into manageable pieces.
Insist on using objective criteria: Replace contests of will with fair standards independent of either side's preferences. Justify your position with a theory of fairness and ask the other side to do the same.
Understanding Both Sides' Interests
Uncovering and understanding interests — both yours and theirs — is perhaps the most crucial skill in principled negotiation. Positions are what people say they want; interests are why they want it. Behind opposed positions often lie compatible interests.
Ask probing "why" questions to identify interests: "What's your basic concern here?" Listen actively and paraphrase what you hear to confirm understanding: "Did I understand correctly that your main worry is...?" Remember that each side has multiple interests that may vary in importance and that different individuals within the same organization may have different priorities.
Give reasons and explain your interests instead of just stating your position. This helps the other side understand your legitimate concerns without feeling threatened. For example, instead of simply demanding a 30-day payment term, explain how faster payment affects your cash flow and operational stability.
Look beyond stated positions for fundamental concerns: People often have both tangible interests (money, resources, time) and intangible ones (maintaining relationships, saving face, feeling respected). Addressing both types increases the likelihood of reaching a satisfying agreement.
Dig deeper when you think you've run into a conflict over a fixed resource like money or territory. These often mask underlying interests that can be addressed through creative solutions — perhaps one side cares more about timing while the other prioritizes certainty, or one values public recognition while the other needs operational control.
Inventing Options for Mutual Gain
Once you understand both sides' interests, you can invent options that create mutual gains.
Imagine two people arguing over whether to open a window in the living room. Their positions are opposed: One wants the window open, the other wants it closed. Rather than just disagree, they explore the interests behind their positions and learn that their interests are compatible: One wants fresh air, the other wants to avoid drafts.
There's a solution that's benefits both sides: opening a window in the next room.
Generating options for mutual gain is hard. Parties often leap to premature judgments or believe that there's a single correct answer. These are some techniques that can help you generate options:
Schedule dedicated brainstorming sessions with clear rules: generate many options without stopping to criticize or evaluate. Aim for quantity over quality initially. Consider involving the other side in brainstorming — this not only produces more creative options but builds investment in the process.
Actively search for items that are low-cost to you but high-value to the other side and vice versa. These asymmetries create the chance to trade. For example, public recognition might cost you nothing but be tremendously valuable to your counterpart, while technical support might be easy for you to provide but critical to their implementation success.
Other differences that create opportunities to trade include:
Different valuations of time (one side might care more about immediate delivery while the other prioritizes long-term stability)
Different risk assessments (one might prefer guaranteed smaller gains while the other welcomes the possibility of larger but uncertain returns)
Different forecasts about future conditions (opening the door to contingent agreements)
Not every issue needs the same solution approach: Some might be resolved through objective criteria, others through trading interests, and still others through creative expansion of resources.
Look beyond obvious solutions by by developing options at different levels of specificity and abstraction. If deadlines are an issue, consider not just a 30 day deadline vs. a 60 day deadline, but also graduated schedules, penalty/bonus systems, or third-party verification mechanisms.
Working with Power Dynamics
Sometimes power dynamics can't be avoided. The most important concept in understanding power is the idea of the BATNA: your Best Alternative to a Negotiated Agreement.
You can enhance your power by developing and understanding your BATNA:
Invent a list of actions you'd take if no agreement is reached
Improve the most promising alternatives
Select the best alternative
Your goal in negotiation should be to protect yourself from accepting a deal worse than your BATNA while maximizing your gains from the negotiation.
Understanding the other side's BATNA is equally important. If their BATNA is better than your offer, they'll see no need to negotiate. When that's the case, consider whether you can change their alternatives.
Beyond your BATNA, negotiation power comes from multiple sources:
Good relationships that foster trust
Deep understanding of interests on both sides
Creative options that meet multiple needs
Objective criteria supporting your position
Strategic commitments about what you will or won't do
Effective communication, especially listening well
By combining principled negotiation with a clear understanding of your BATNA, you can achieve better outcomes regardless of power imbalances, creating agreements that genuinely serve both parties' interests while building foundations for productive long-term business relationships.
