Successful Negotiation: The 4 Steps of the Harvard Method for Lasting Agreements

In professional as well as personal life, we negotiate constantly with our clients, suppliers, managers, and collaborators. Yet most of us face these situations without a clear method, relying solely on intuition. The results are often disappointing: we give in too easily, clash unnecessarily, or strike a deal that leaves no one truly satisfied.

Roger Fisher and William Ury, founders of the Harvard Negotiation Project, dedicated their careers to studying what separates great negotiators from the rest. Their book Getting to Yes, published in 1981 and translated into more than 30 languages, remains the global gold standard on the subject today. Their central premise is simple yet radical: negotiation is not a battle of wills. It is a problem-solving exercise.

Here are the four fundamental steps of this method, illustrated with concrete examples, along with the tools to handle negotiations when things get complicated. 

What negotiation really means

Let’s start by deconstructing a common misconception. For many, a successful negotiation means winning as much as possible for yourself at the expense of the other party. We talk about power struggles, arm-wrestling, and concessions. This view turns negotiation into a battle, and in any battle, there is a winner and a loser.

Fisher and Ury offer a different vision: if you are wondering who is winning, you have already lost, because you have missed the point. The true goal of a negotiation is to find a solution that satisfies the interests of both parties while preserving the relationship.

The orange example: when compromise leaves everyone empty-handed

Two children are fighting over an orange. The parent, striving for fairness, cuts it in half and gives half to each child. The first child eats the fruit and throws away the peel. The second child uses the peel to bake a cake and throws away the fruit.

If the parent had taken the time to ask why each child wanted the orange, both could have received 100% of what they actually needed. The automatic compromise of sharing 50/50 cut their satisfaction in half. This example perfectly illustrates why understanding real behind-the-scenes interests is far more important than just finding an even split. 

The 4 steps to successful negotiation using the Harvard method

Step 1: Separate the people from the problem

Before starting any negotiation, visualize a vertical line separating two distinct realities: on one side, the person with their ego, emotions, and perception of the world; on the other, the problem to be solved. These two realities must never merge.

The goal is to be soft on the people and hard on the problem. In practice, most negotiators do the opposite: they are either too soft on the problem to preserve the relationship, or too hard on the problem and end up being hard on the person as well. Both mistakes are costly.

The people we negotiate with have different viewpoints, easily threatened egos, and a natural tendency to confuse their perception with reality. Their intentions can easily be misread. Our own emotions—anger, frustration, impatience—can just as easily block an agreement.

One of the most effective ways to prevent these road blocks is to build a relationship with the other party before the negotiation even begins. Studies show that simply getting to know your counterpart informally increases negotiation success rates by 25% to 30%. Arrive early, stay late, and show genuine interest in the person.

Step 2: Focus on interests, not positions

Let's look at the library example: one man wants to open the window to get some fresh air, while the other wants to close it to keep his papers from blowing away. If they only argue their positions (open vs. closed), the discussion goes in circles. But when they look at the underlying interests (fresh air vs. no wind), a creative solution emerges: opening a window in an adjacent room.

Positions are clear and specific. Interests are often hidden or vague. To uncover them, you only need to ask one question: why? Why do they want what they are asking for? What truly matters to them?

Once you identify these interests, talk about them openly. People listen better when they feel understood. And make sure to share your own interests: the other party might not know them. To turn your interests into a concrete option, ask yourself: if we reach an agreement tomorrow, what exactly do I want to see happen?

Step 3: Insist on objective criteria and fair standards

Even when interests are clearly on the table, conflicts can still arise. You want lower rent; your landlord wants to raise it. Instead of fighting over positions, the Harvard method recommends relying on objective criteria—impartial standards that do not depend on personal opinions.

These criteria can take many forms: market prices, legal requirements, independent expert opinions, or professional and industry standards. The advantage is massive: once you suggest looking at the standard rules, you are no longer demanding anything; the objective framework speaks for you. This naturally reduces resistance from the other party.

A great practice is to define these standards together before negotiating:
