Abstract

This text presents key ideas from David A. Lax and James K. Sebenius’s 3-D Negotiation framework, which views negotiation as the interaction of three simultaneous dimensions: tactics at the table, deal design that uncovers true economic and non-economic interests, and the broader setup that shapes the situation off the table. Focusing on interests is central to this approach because stated positions often mask implicit goals, constraints, and concerns. The discussion highlights perspective-taking, careful assessment of one’s own priorities, and the use of classic tools such as BATNA and ZOPA, while warning against reducing analysis to a single distributive variable such as price. The text also identifies wider contextual factors that influence outcomes, including relationships, emotions, and cultural orientations toward either results or relationships. It stresses the role of the “social contract” or spirit of the agreement in establishing expectations, trust, and conflict-resolution norms, and it notes how process choices and tactics (e.g., anchoring) can distort results. Finally, it addresses ethical tensions in negotiating behaviour through deontological, consequentialist, Machiavellian, and virtue-based lenses, and it concludes with four practices to safeguard interests: ask and probe, map interests using public information, leverage internal sources, and consult knowledgeable advisers.

Professors David A. Lax and James K. Sebenius, who are involved in the Harvard University Negotiation Project, in their book 3-D Negotiation. Powerful Tools to Change the Game in Your Most Important Deals (2006) offer new perspectives when it comes to conducting negotiations.

According to this approach, negotiations should be understood as three-dimensional, with three elements occurring more or less simultaneously throughout the actual negotiation. These dimensions are: a) Tactics, which involve persuasive manoeuvres and give-and-take. It is worth noting that poor tactics can ruin a negotiation; b) Deal design: beyond the obvious, this involves uncovering the parties’ true economic and non-economic interests; and c) Setup: off the table, which shapes and reshapes the situation (Lax, Sebenius, 2006, 9). . 

Below, we will examine the topic of exploring interests from the perspective of the Minerva Strategy Blog.

Lax and Sebenius begin by defining interest as whatever you care about that is potentially at stake in the outcome (Lax, Sebenius, 2006, 76).  Their entire approach is based on the observation that the interests stated at the negotiating table are one thing, whereas the parties’ actual or implicit interests are quite another, whether or not these have been clearly articulated. 

When exploring these interests (whether explicit or implicit) in the handling of information about the other party, it is essential to practice, at various stages of the negotiation process, the exercise of putting oneself in the other person’s shoes. It’s also vital for oneself or the negotiating team to calmly assess the true interests at stake: what one wants from the negotiation, what could be gained, and what could be lost. In the standard terminology of Negotiation Theory, what is the best alternative to a no-deal outcome (BATNA), and how is the Zone of Possible Agreement (ZOPA) established between the parties? 

However, Lax and Sebenius’s emphasis on the importance of (actual) interests within the framework of three-dimensional negotiation highlights the fact that focusing all one’s attention in negotiations on linear distributive dimensions—such as price negotiation—can cause one to lose sight of a range of potentially richer interests.

From this perspective, analysing BATNA and ZOPA can be useful tools, but not by focusing on a single variable; rather, by taking into account all the factors at play within the negotiating context.  

In many negotiations, relationships are a key factor to bear in mind. Sometimes, emotions guide the parties’ behaviour, and such feelings can distort certain expectations. On other occasions, poor or mediocre results are accepted simply to maintain the relationship. On this point, Lax and Sebenius distinguish between countries that focus on relationships—such as those in Southern Europe and Latin America—and others that focus on results, such as Anglo-Saxon and Northern European countries  (Lax, Sebenius, 2006, 74). 

Another factor to bear in mind is the social contract; beyond its strictly economic dimension, this governs people’s expectations regarding the nature, scope and duration of the agreement, the process to be followed, and the way in which unforeseen events are handled. As Lax and Sebenius state, it is “the spirit of the agreement.” It is important to clearly understand this broad framework to avoid conflicts or to resolve them without too much difficulty. It is about establishing relationships within a framework of trust, within the framework of a shared negotiating culture, where the obligations of the parties and the usual way of resolving potential conflicts are clearly established (Lax, Sebenius, 2006, 74).

The third factor is the process itself. Certain negotiation processes often influence the outcome, and sometimes negotiators employ tricks and tactics, such as anchoring. These tactics can be particularly detrimental to one of the parties, who must be able to identify them and defend their position, especially when they are unaware of these strategies or lack experience in negotiation scenarios. Another important point is to distinguish the negotiating table from the wider negotiating context. It is usually easier to make progress in negotiations in informal settings (Lax, Sebenius, 2006, 75).    

Finally, one factor to bear in mind is ethics. Certain aspects of some negotiations may be morally controversial; for example, some negotiating tactics that involve withholding or manipulating information from the other party. From an ethical standpoint, the response will differ between the deontological model, with its duty to always tell the truth; the consequentialist model, which advocates the greatest happiness for the greatest number of people; the Machiavellian model, focused on success; and the virtuous model, which proposes acting as a virtuous person would in that situation  (Lax, Sebenius, 2006, 75).

Lax and Sebenius argue that we should not confuse negotiating positions with a broader set of actual interests, and they propose four practices that will help you safeguard your interests:

–Ask, listen and probe

Information about the other party’s interests is essential. The best way to get this is to listen carefully and gauge how they might respond to the negotiation map’s options. 

–Use public sources to map interests

When important decisions need to be made, it is advisable to consult public records and the relevant institutions to gather objective information. Having reports from independent bodies and other credible sources of information is also beneficial.

–Tap internal sources

Naturally, if you can obtain firsthand information from someone who understands the other party’s interests, this can be particularly useful. It is also important to have information about the negotiator and the people involved, as well as their explicit, implicit and underlying interests.

–Tap knowledgeable advisers

In complex business situations, people often turn to professionals such as lawyers or intermediaries. Lax and Sebenius recommend asking them about their experience in such situations. Perhaps this is because – as Aristotle pointed out many centuries ago – experience can help one to better understand a particular situation (Lax, Sebenius, 2006, 77-79).

Julius Caesar, Zone of Possible Agreement (ZOPA) in Civil War

In a book entitled Civil War, Julius Caesar narrates the political and military conflicts with the Roman Senate and especially with his rival Pompey. These led to a veritable civil war between contending groups looking to seize power.

In this post, I will analyse the successive peace proposals made by Julius Caesar and Pompey, through the lens of ZOPA analysis. The Zone of Possible Agreement – known as ZOPA – is a frame of reference that is relevant to any negotiation. It is defined between the parties’ two BATNAs. That is, between each player’s Best Alternatives to a Negotiated Agreement -BATNA-. Another way of expressing this is to define the ZOPA as the margin between the two reserve prices of each party. In other words, the minimum prices that the parties are willing to accept in a negotiation.

In the work Civil War, the author describes how the conflicts for power in Rome arose. He explains that Pompey made Julius Caesar the following proposal: “Caesar should return to Gaul, withdraw from Rimini, discharge his armies; if he met these terms, Pompey would go to Hispania. Until there was assurance that Caesar would do what he had promised, the consuls and Pompey would not cease levying levies” (I.10).

The analysis from ZOPA is that the parties’ BATNAs do not allow for a deal on these terms. The proposed deal is that Julius Caesar must withdraw and disarm while his adversaries continue to arm. Julius Caesar would rather fight with his present forces than disarm. Pompey concedes to go to Hispania but only after he has assembled  the troops. The agreement is unbalanced in terms of the strategic relevance of the concessions between the parties. Therefore, the party that is asked to make a greater effort – to disarm – will easily find a better alternative to the proposed agreement.

Events progressed and it was now Julius Caesar who made a proposal to Pompey for a peace agreement, on the following terms: “that they should cause no more harm to themselves or to the Republic. They themselves were already enough proof, by their own disasters, of how much power fortune has in war. This was the only occasion to treat of peace, so long as both were confident of their strength, and their power was considered equal; if fortune helped only a little to one of the two, he who considered himself superior would not admit of terms for peace, nor consider himself satisfied with a part in which he trusted to possess all.

Since he had not been able to reach an agreement before, the terms for peace had to be requested in Rome from the Senate and the Roman people” (III. 10). (III. 10)

This agreement is based on equality of forces and uses the figure of an arbitration by the Senate. It is interesting the reflection that Julius Caesar makes where equality of forces is more favourable to peace, while if one party is more fortunate in combat, it will seek to defeat the other in battle.

What Julius Caesar means is that agreement is possible if the two sides have similar BATNAs. If one side has a very good BATNA – it has a good chance of winning the war – there is no possibility of agreement. The Zone of Potential Agreement -ZOPA- will expand with the uncertainty of the final outcome from two medium BATNAs.

Turning to a third party to settle a dispute is a legitimate, and widely used, way to do so, as long as its impartiality of judgement is guaranteed.

To Julius Caesar’s proposal of peace, Pompey’s reply was: “What does life or the city matter to me if it is to be believed that I have it for Caesar’s benefit; this belief cannot be erased, since it will be believed that by him I have been restored to Italy, when I came out” (III.18).

Here it is worth remembering Fisher and Ury’s rule “Separate the persons from the problem“. One party does not want to enter into a agreement because any solution will look like a success for the other party. In addition to an issue of hierarchy between the two, what seems to be relevant here are the emotions that stand in the way of any agreement. This always leads to conflict.

Proof of this are the words of an officer of the Pompeian army, named Labienus, who at one point in the negotiations said: “Stop talking about peace, for there can be no peace for us unless Caesar’s head is brought to us” (III.20).

It seems clear that there is an emotional problem and that the declared aim of one side is the death of Julius Caesar. In this case, there is no ZOPA. No agreement is possible if one side only wants Caesar’s death to make peace. The other side’s alternative is to fight and defend Julius Caesar’s life.

Pompey’s end also teaches us about strategy. His armies were defeated by Julius Caesar’s armies and set sail for Syria. There he sought help from Ptolemy, king of Egypt, who was at loggerheads with his sister Cleopatra, who later had a relationship with Julius Caesar that has been mythologised. Out of fear of the threat he posed or out of contempt for misfortune, Ptolemy’s advisors agreed to answer Pompey kindly in public and secretly sent two emissaries to kill him (III.104).

This story between Julius Caesar and Pompey can make us reflect on some aspects: a) On the need to establish a Zone of Possible Agreement (ZOPA) according to the BATNA of the parties, their Best Alternative to a Negotiated Agreement. The key to negotiating power is to have a good BATNA, a good alternative to negotiate; b) Proper management of emotions. They should not be an objective, in themselves, of the negotiation; c) Approach of third parties when their impartiality of judgement is guaranteed.
