For decades, negotiators have been working out agreements by focusing on interests, not positions. But the messy problem of how to share the gains created by deals has remained unresolved--until now. The answer, argue Yale's Nalebuff and NYU's Brandenburger, lies in accurately identifying and sizing the negotiation "pie," which they define as the additional value produced by an agreement to work together. It's the value over and above the sum of the two sides' best alternatives to a negotiated agreement, or BATNAs. The pie most people have in their heads, however, is the total value available to be split. Because of this, they argue over the wrong numbers and issues, taking positions that they think are reasonable but that are in fact self-interested. Once the pie is properly understood, the allocation rule is simple: The parties in a negotiation have an equal claim on the pie, so it should be divided evenly. This is true regardless of what they can accomplish on their own, because both are equally needed to create the gains. This principle can be applied in a variety of increasingly complicated real-world scenarios, which the authors walk readers through in this article.
"Co-opetition"--cooperating with a competitor to achieve a common goal or get ahead--has been gaining traction for three decades. Yet many companies are uncomfortable with the concept and bypass the promising opportunities it presents. In this article two professors who helped introduce the approach offer a framework for deciding whether to team up with a rival, drawing on examples from Apple and Samsung, DHL and UPS, Ford and GM, and Google and Yahoo. Their advice: Start by analyzing what each party will do if it chooses not to cooperate and how that will affect industry dynamics. Sometimes working together is a clear win, but even if it isn't, it may still be better than allowing someone else to take your place in the deal--which could leave you at a disadvantage. Next, it's critical to figure out how to cooperate without giving away your "secret sauce"--your current advantages. Once you've done that, you'll need to craft an agreement that clearly outlines the deal's scope, who is in charge, how the arrangement could be unwound if needed, and how gains will be divided. You'll also have to manage resistance within your own firm and alter internal mindsets. Co-opetition requires mental flexibility, but firms that develop it can gain an important edge.
