Roger Fisher and William Ury published Getting to Yes in 1981 and changed how the world negotiates. The book's central argument: most negotiations fail not because the parties cannot agree but because they negotiate over positions rather than interests. Positional bargaining — "I want $100," "I'll pay $80," they settle at $90 — treats negotiation as a zero-sum game where every dollar one side gains is a dollar the other loses. Interest-based negotiation asks a different question: why does each side want what it wants? And in the answer to that question, the pie almost always expands.
The classic illustration: two children fight over an orange. A positional solution cuts the orange in half. An interest-based solution discovers that one child wants the juice and the other wants the peel for baking — and both get 100% of what they actually need. The orange was never the issue. The positions were a proxy for interests that, once understood, were entirely compatible. Fisher and Ury's insight is that this structure — apparently conflicting positions masking compatible interests — describes the vast majority of negotiations, from salary discussions to international treaties. The pie looks fixed only because the parties are looking at positions. When they look at interests, the pie expands.
Amazon's marketplace is the most financially significant win-win structure in modern business. Before the marketplace launched in 2000, Amazon was a retailer competing with other retailers for customers. The marketplace created a structure where Amazon wins (commission revenue, expanded selection without inventory risk, increased traffic that reinforces the flywheel), third-party sellers win (access to hundreds of millions of customers, fulfillment infrastructure through FBA, trust transfer from the Amazon brand), and customers win (exponentially broader selection, price competition among sellers, consistent delivery experience). The marketplace now accounts for over 60% of Amazon's unit sales. The win-win structure did not just add a revenue stream. It transformed Amazon's business model from linear retail to platform economics — and the transformation was possible only because the structure created genuine value for all three parties simultaneously.
Costco's supplier relationships demonstrate win-win operating at the operational level. Costco caps its markup at 14% — a self-imposed constraint that looks like margin sacrifice. The constraint creates a win-win: suppliers accept lower per-unit margins because Costco delivers guaranteed high volume and predictable demand, which reduces the supplier's sales, marketing, and distribution costs. Costco gets lower wholesale prices because suppliers factor the guaranteed volume into their pricing. Customers get prices that undercut conventional retail by 20–40%. The structure is stable because every participant is better off inside the arrangement than outside it — the definition of a sustainable win-win. Costco's membership renewal rate of 92% is the economic proof: customers stay because the value proposition is real, not because they are locked in.
Win-win is not naive idealism about human nature. It is the only sustainable long-term strategy because win-lose erodes trust and creates adversaries. A supplier squeezed on margin in year one reduces quality in year two, finds an alternative buyer in year three, and becomes a competitor in year four. A negotiation that extracts maximum value from the counterparty today generates a counterparty who spends tomorrow figuring out how to extract that value back — or how to exit the relationship entirely. The mathematics are simple: repeated interactions with the same parties dominate business life, and in repeated games, cooperation produces higher cumulative payoffs than exploitation. Win-win is not generosity. It is compound interest applied to relationships.
Section 2
How to See It
Win-win reveals itself through durability. Arrangements that persist for years without renegotiation, relationships where both parties actively invest in the partnership's success, and market structures where participants resist alternatives despite having them — these are the signatures of genuine win-win. The diagnostic is the absence of friction: win-win structures do not require enforcement because both parties are motivated to maintain them.
Platform Business
You're seeing Win-Win when Shopify's business model aligns Shopify's success with merchant success. Shopify earns revenue through subscriptions and payment processing — which means Shopify only grows when its merchants grow. This alignment is structural, not rhetorical. Every product decision, engineering investment, and platform improvement Shopify makes is filtered through the question: does this help our merchants sell more? The alignment eliminates the adversarial dynamics that plague platforms where the platform's revenue model conflicts with user interests. Merchants trust Shopify because the incentive structure makes Shopify's self-interest indistinguishable from merchant-interest.
Employment
You're seeing Win-Win when Netflix's compensation philosophy — pay top of market, no vesting cliffs, no retention bonuses — creates a structure where the employee's economic interest (maximum current compensation) aligns with Netflix's operational interest (the highest-performing person in every role, with no obligation to retain underperformers through golden handcuffs). The absence of retention mechanics means that every employee who stays at Netflix stays because the role is the best available option — not because leaving would sacrifice unvested equity. The win-win: Netflix gets voluntary commitment rather than contractual captivity, and employees get compensation that reflects their market value rather than their sunk costs.
Investing
You're seeing Win-Win when Berkshire Hathaway's acquisition model creates win-win structures between Buffett and the founders who sell their companies. Buffett offers sellers something no other acquirer provides: operational autonomy. Founders who sell to Berkshire keep running their businesses. They keep their management teams, their culture, their decision-making authority. In exchange, Buffett gets businesses he doesn't need to manage, run by people who know them better than any outside operator could. The win-win is so durable that it has become Berkshire's competitive advantage in deal-making — sellers actively prefer Berkshire over higher bidders because the non-economic terms (autonomy, legacy preservation) are worth more to them than additional purchase price.
Customer Relationships
You're seeing Win-Win when Amazon Prime creates a structure where customer behaviour (increased purchase frequency driven by free shipping) aligns with Amazon's economics (higher lifetime value that justifies the logistics investment). The customer wins because shipping costs disappear and delivery accelerates. Amazon wins because Prime members spend roughly 2.3x more than non-Prime members. The win-win is self-reinforcing: as more customers join Prime, Amazon can invest more in logistics infrastructure, which improves the delivery experience, which attracts more Prime members. The flywheel spins because both sides are pushing.
Section 3
How to Use It
Win-win is not a negotiation tactic. It is a design principle — a way of structuring agreements, partnerships, and business models so that value creation, not value capture, is the primary dynamic. The shift from positional to interest-based thinking is the foundational move. But the real skill is structural: designing arrangements where the participants' incentives are aligned so that each party's self-interested behaviour automatically benefits the other parties.
Decision filter
"Before entering any negotiation or designing any partnership, I map each party's interests — not their positions, but their underlying needs, fears, and priorities. Then I ask: is there a structure where satisfying my interests simultaneously satisfies theirs? If yes, I design for that structure. If no, I ask whether I'm looking at interests or still looking at positions — because the distinction determines whether the pie is fixed or expandable."
As a founder
Your most important win-win is the one between your company and your customers. If your business model requires customers to lose for you to win — hidden fees, dark patterns, planned obsolescence, information asymmetry that you exploit rather than resolve — the model is structurally fragile. Customers will leave as soon as a competitor offers a transparent alternative. Build a model where your revenue grows because your customers' outcomes improve. SaaS pricing tied to usage. Marketplace commissions tied to seller success. Success fees that align your revenue with customer results. The alignment is not just ethical. It is the strongest possible competitive position, because a competitor cannot displace you by offering better alignment when your alignment is already total.
The second win-win: between founders and early employees. Equity compensation is a win-win structure — if the equity is real. When early employees share meaningfully in the upside they helped create, their incentive to build the company is aligned with the founders' incentive. When equity is diluted to insignificance or structured with terms that prevent employees from ever realising value, the win-win collapses into a win-lose that the employees eventually recognise. The best founders understand that generous equity for early employees is not charity. It is the highest-returning investment the company makes — because aligned incentives produce discretionary effort that no salary can purchase.
As an investor
The fund model itself is a win-win architecture — or should be. The standard venture structure (2% management fee, 20% carried interest) aligns investor and LP interests imperfectly: the management fee creates a floor that rewards fund size regardless of returns, and the carry creates asymmetric upside that can incentivise excessive risk. The best fund managers design additional alignment mechanisms — co-investment rights, management fee offsets, hurdle rates — that strengthen the win-win between GP and LP.
In portfolio company relationships, the win-win diagnostic is simple: does the investor add value that exceeds the cost of the capital? An investor who provides only money is a commodity supplier. An investor who provides capital plus customer introductions, hiring networks, strategic guidance, and crisis management creates a win-win where the founder's success and the investor's return are jointly maximised by the investor's active contribution. The investors who consistently attract the best deal flow are not those who offer the highest valuations. They are those whose value-add creates a win-win that founders cannot replicate with commodity capital.
As a decision-maker
Internal negotiations — between departments, between teams, between functions — default to win-lose when resources are scarce. Engineering wants more headcount. Sales wants more territory. Marketing wants more budget. Each department frames its request as a position, and the executive's job becomes arbitration: dividing a fixed pie among competing claims. The win-win reframe asks: what are the underlying interests? Engineering wants to ship faster. Sales wants to close more deals. Marketing wants to generate more pipeline. These interests may be compatible — an investment in developer tools that accelerates engineering output might also improve the product that sales is selling and the story that marketing is telling. The reframe does not always work. Sometimes resources are genuinely fixed and allocation is genuinely zero-sum. But the default should be to search for the expandable pie before accepting the fixed one.
The organisational design question: are your team incentive structures win-win or win-lose? If marketing is measured on leads generated and sales is measured on leads closed, the metrics are aligned — both teams win when leads convert. If marketing is measured on leads generated and sales is measured on revenue per rep, the metrics conflict — marketing has an incentive to generate high-volume, low-quality leads that inflate their numbers while making sales' job harder. Misaligned metrics create structural win-lose dynamics that no amount of cross-functional collaboration initiatives can fix.
Common misapplication: Treating win-win as compromise. Compromise — splitting the difference, meeting in the middle — is not win-win. It is positional bargaining with good manners. True win-win expands the pie so that both parties get more than they would through compromise. The orange example again: splitting the orange is compromise. Discovering that one wants the juice and the other wants the peel is win-win. The difference is not semantic. Compromise leaves value on the table. Win-win creates value that did not previously exist.
Second misapplication: Pursuing win-win with parties who are playing win-lose. Win-win requires reciprocity. A negotiator who is transparently pursuing win-win while the counterparty is covertly pursuing win-lose will be exploited — their openness about interests becomes intelligence that the counterparty uses against them. The discipline is to test for reciprocity early: share a small interest and observe whether the counterparty reciprocates with equivalent transparency. If they do, invest in the win-win process. If they don't, adjust your strategy — because win-win with an adversarial counterparty is not idealism. It is self-harm.

The Mechanism
Section 5
Founders & Leaders in Action
The two leaders below built entire business models on win-win architecture — structures where every participant's self-interested behaviour simultaneously creates value for every other participant. Both understood that the most durable competitive advantages are not zero-sum positions defended against competitors but positive-sum structures that competitors cannot replicate because the win-win network effects compound over time.
What distinguishes them from leaders who merely speak about partnership and collaboration: they designed the incentive structures, pricing models, and platform mechanics so that win-win was not a cultural aspiration but a mathematical inevitability. The system produced cooperation without requiring it.
Bezos built the Amazon flywheel on win-win mechanics so fundamental that each participant's self-interest powers everyone else's outcome. The marketplace invited third-party sellers onto Amazon's platform — a move that initially seemed irrational (why help competitors sell alongside your own products?). The win-win logic was structural: more sellers meant more selection, more selection attracted more customers, more customers attracted more sellers, and the increased volume lowered costs for everyone through economies of scale. Each participant — Amazon, sellers, customers — optimised for their own interest, and the system converted that self-interest into collective value.
The FBA (Fulfillment by Amazon) programme extended the win-win. Sellers gained access to Amazon's logistics infrastructure — the warehousing, shipping, and customer service that would cost millions to build independently. Amazon gained inventory positioned in its fulfillment centers, which increased delivery speed for customers and utilisation rates for warehouses. Customers gained Prime-eligible products from sellers who could never have offered two-day shipping on their own. Each party received something they valued (sellers: logistics, Amazon: utilisation, customers: speed) and paid for it with something they could afford to give (sellers: commission, Amazon: infrastructure sharing, customers: Prime membership). The architecture was win-win by design, not by intention.
Amazon Prime is itself a win-win instrument. Customers pay an annual fee and receive free shipping, which changes purchasing behaviour — Prime members buy more frequently because the marginal shipping cost is zero. Amazon accepts the logistics cost of free shipping and receives dramatically higher customer lifetime value. The win-win compounds: more Prime members justify more investment in logistics infrastructure, which enables faster delivery, which makes Prime more valuable, which attracts more members. The structure has no natural ceiling because both sides benefit from scale.
Lütke designed Shopify's business model as a win-win machine: Shopify succeeds only when its merchants succeed. The revenue model — subscription fees plus a percentage of payment volume processed through Shopify Payments — means Shopify's top line grows when merchants sell more. This alignment is not accidental. Lütke explicitly rejected advertising-based monetization (which creates incentives to divert customer attention from merchants to advertisers) and data-reselling (which creates incentives to exploit merchant data rather than protect it). Every monetization decision was filtered through the question: does this align Shopify's incentive with merchant success?
The Shopify ecosystem extends the win-win to app developers and theme designers. Developers build tools that extend Shopify's platform capabilities — and Shopify shares revenue with them through the app store. The win-win: developers get distribution to millions of merchants they could never reach independently, and Shopify gets a product development force of thousands of developers it does not employ or manage. The ecosystem produces more innovation than Shopify's internal team could create, at lower cost, with the risk distributed across thousands of independent developers rather than concentrated on Shopify's balance sheet. Merchants benefit from the expanded tool ecosystem. Developers benefit from the merchant base. Shopify benefits from both.
Lütke's "arm the rebels" philosophy frames Shopify's mission as enabling independent merchants to compete with Amazon — which positions Shopify's commercial success as a function of merchant empowerment rather than merchant dependence. The framing is strategically significant: merchants trust Shopify because the business model makes Shopify's growth dependent on merchant growth. A platform that grows by extracting value from its participants creates adversaries. A platform that grows by creating value for its participants creates advocates. Shopify's merchant retention rate reflects the difference.

Connected Models
Win-win is the operating expression of positive-sum game theory. It depends on trust (without trust, parties cannot reveal interests), connects to BATNA (your alternative determines your negotiating power within the win-win frame), and produces the relationship durability that Nash Equilibrium describes mathematically. The connections below map win-win's dependencies, reinforcements, and the models that explain both its power and its failure modes.
Reinforces
BATNA
BATNA — Best Alternative to a Negotiated Agreement — is the foundation of negotiating power within any framework, including win-win. A strong BATNA does not contradict win-win. It enables it. A negotiator with a strong alternative can afford to walk away from arrangements that are not genuinely win-win, which paradoxically makes genuine win-win more likely — because the counterparty knows that an unfair structure will not be accepted. Fisher and Ury's framework explicitly integrates BATNA: know your alternative before entering any negotiation, improve it wherever possible, and use it as the floor below which no agreement is acceptable. The strongest win-win negotiators are those whose BATNA is so strong that they negotiate from abundance rather than necessity — which means they can focus on creating value rather than protecting themselves.
Reinforces
[Game Theory](/mental-models/game-theory)
Win-win is the practical application of cooperative game theory. Nash's bargaining solution, the Shapley value, and the core of cooperative games all describe outcomes where rational players maximise joint surplus rather than individual shares. Game theory provides the mathematical proof that win-win is not idealism but optimality: in repeated interactions with communicating parties, the outcome that maximises joint value is the one that rational actors should pursue. The reinforcement is foundational — game theory explains why win-win works, and win-win demonstrates game theory's predictions in operational reality.
Reinforces
[Trust](/mental-models/trust)
Win-win requires trust and builds trust simultaneously. Interest-based negotiation requires parties to disclose their true interests — a vulnerability that is only rational if the counterparty can be trusted not to exploit the disclosure. Trust enables the openness that win-win requires. Win-win, once executed successfully, builds the trust that enables future win-win negotiations. The reinforcement is circular and compounding: each successful win-win interaction increases trust, which makes the next win-win interaction easier, which builds more trust. The Costco-supplier relationships are the operational proof — decades of win-win dealing have built trust that makes contract negotiations minimal because both parties know the other will deal fairly.
Section 8
One Key Quote
"The reason you negotiate is to produce something better than the results you can obtain without negotiating."
— Roger Fisher & William Ury, Getting to Yes (1981)
The quote sounds obvious until you realise how often negotiators forget it. Positional bargaining — the default mode — frequently produces outcomes that are worse for both parties than their pre-negotiation alternatives, because the adversarial dynamic generates resentment, erodes trust, and consumes time and resources that exceed the value of the concessions won. A negotiation that takes three months, involves lawyers on both sides, and produces a split-the-difference outcome may have cost both parties more in process than they gained in result. Fisher and Ury's standard is ruthlessly practical: the only justification for negotiating is an outcome better than your BATNA. If the negotiation process itself is so costly or adversarial that the outcome is worse than walking away, the negotiation has failed — regardless of whether an agreement was reached.
The strategic implication: begin every negotiation by clearly defining your BATNA, then evaluate every proposed outcome against it. Win-win is not the goal in itself. The goal is an outcome better than your alternative. Win-win is the method most likely to produce that outcome in repeated interactions — because interest-based negotiation creates value that positional bargaining cannot, and the created value means both parties can exceed their BATNAs rather than merely matching them. The best negotiations leave both parties feeling they got more than they could have gotten alone. That feeling is not sentiment. It is the economic output of a process that created value rather than merely redistributed it.

Analyst's Take
Faster Than Normal — Editorial View
Win-win is the most misunderstood concept in business strategy. People hear "win-win" and think: be nice, split the difference, avoid conflict. That is not win-win. That is conflict avoidance dressed in negotiation language. True win-win is harder than win-lose — it requires understanding the counterparty's interests deeply enough to find structures that serve both parties simultaneously. It demands creativity, not concession. The founder who says "we have a win-win partnership" and means "we split the economics 50/50" does not understand the concept. The founder who says "we structured the deal so that their success drives our revenue and our platform drives their growth" — that is win-win.
The pattern I track most closely: whether a company's business model is structurally win-win or structurally win-lose with its customers. Companies with win-win customer models — where revenue grows when customer outcomes improve — build durable competitive advantages. Shopify's revenue grows when merchants sell more. Stripe's revenue grows when businesses process more payments. AWS's revenue grows when customers scale their infrastructure. In each case, the company cannot succeed without its customers succeeding. Companies with win-lose customer models — where revenue grows through fees that don't correlate with customer value, through information asymmetry exploited against the customer, or through switching costs that trap rather than retain — build fragile advantages that regulation, competition, or customer revolt will eventually destroy.
Costco is the case I study most carefully because the win-win is so extreme it looks like poor business strategy. Capping markup at 14% when competitors operate at 25–50% margins? Paying employees above market when every competitor squeezes labour costs? Offering generous return policies when the math says restrict them? Each decision looks like margin sacrifice in isolation. In combination, they produce the most loyal customer base in retail (92% renewal), the most productive workforce in the sector (revenue per employee far exceeds competitors), and a supplier network that prioritises Costco allocation because the relationship is profitable and fair. The win-win compounds: loyal customers drive volume, volume strengthens supplier relationships, strong suppliers provide better pricing, better pricing strengthens customer loyalty. The flywheel turns because every participant benefits, and no participant has an incentive to defect.
The danger I warn against: confusing correlation of interest with alignment of interest. Two parties can have correlated interests — they both benefit from the same market trend — without having aligned interests. A startup and its venture investor both benefit from the company's valuation increasing. But their interests diverge on timeline (the investor has a fund life), risk preference (the investor has a portfolio), and exit terms (the investor has liquidation preferences). Correlation creates the appearance of win-win. Alignment creates the reality. The best partnerships make alignment structural — through contract terms, incentive design, and governance mechanisms that ensure the parties' interests remain aligned even when circumstances change.
Section 10
Test Yourself
The scenarios below test whether you can distinguish between genuine win-win structures (where both parties are better off inside the arrangement than outside it) and arrangements that masquerade as win-win but are actually win-lose in disguise. The diagnostic is sustainability: genuine win-win structures are self-reinforcing because both parties are motivated to maintain them. Win-lose structures disguised as win-win eventually collapse when the losing party recognises the imbalance.
Is this genuine win-win or win-lose in disguise?
Scenario 1
A SaaS company offers its enterprise clients a pricing structure where the monthly fee decreases as the client's usage increases — the more they use the product, the lower their per-unit cost. The company's internal analysis shows that high-usage clients have 95% retention rates, generate reliable recurring revenue, and produce the usage data that improves the product for all customers. The CFO argues the volume discounts are eroding margin.
Scenario 2
A food delivery platform charges restaurants a 30% commission on every order processed through the platform. The platform positions this as win-win: restaurants get access to customers they would not otherwise reach, and the platform provides delivery logistics. During a downturn, multiple restaurant owners publicly complain that the 30% commission makes delivery orders unprofitable — they fulfil orders at a loss to maintain visibility on the platform, fearing that delisting will reduce their overall brand presence.
Scenario 3
A venture capital firm offers portfolio companies a unique term: instead of taking a board seat, the firm provides an opt-in advisory model where partners with relevant domain expertise are available on request but do not attend board meetings or receive regular updates. The firm's fund returns have outperformed benchmark by 3x over three fund cycles. Founders report that the model reduces governance overhead and allows them to seek advice when it is needed rather than performing for a board audience.
Section 11
Top Resources
The win-win literature spans negotiation theory, game theory, and business model design. Start with Fisher and Ury for the foundational negotiation methodology, extend to Axelrod for the evolutionary game theory that explains why cooperation dominates in repeated interactions, and deepen with Brandenburger and Nalebuff for the application of game theory to business strategy. The academic foundation is Nash's cooperative game theory. The practical application is principled negotiation. The strategic application is business model design that embeds win-win into the structure of the enterprise.
The foundational text on interest-based negotiation. Fisher and Ury's four principles — separate people from problems, focus on interests, generate options for mutual gain, use objective criteria — transformed negotiation from an adversarial art into a principled methodology. The book provides the conceptual framework and practical techniques for shifting any negotiation from positional bargaining to value creation. Translated into thirty-six languages and still the most widely taught negotiation text in law schools, business schools, and diplomatic training programmes worldwide.
Axelrod's iterated Prisoner's Dilemma tournaments proved that cooperative strategies dominate exploitative strategies in repeated interactions — the mathematical foundation for win-win as a superior long-term strategy. The book demonstrates that "tit-for-tat" (cooperate initially, then mirror the other party's behaviour) produces the highest cumulative payoffs across any sufficient number of interactions, explaining why win-win is not idealism but optimality in any relationship where the parties expect to interact again.
Brandenburger and Nalebuff apply game theory to business strategy, demonstrating that companies simultaneously compete and cooperate with the same players — and that the most successful strategies actively manage both dynamics. The book introduces the Value Net framework for mapping the relationships among customers, suppliers, competitors, and complementors, providing the strategic architecture for designing win-win business structures at the industry level.
Voss, a former FBI hostage negotiator, provides the tactical complement to Fisher and Ury's principled framework. The book demonstrates that empathy-based techniques — tactical empathy, mirroring, labelling, calibrated questions — create the psychological conditions for win-win outcomes in high-stakes negotiations. Voss's insight: understanding the counterparty's emotional reality is not a soft skill but a tactical advantage that reveals interests positions cannot express.
Schelling's game-theoretic analysis of bargaining, conflict, and commitment provides the theoretical foundation for understanding when win-win is possible and when it is not. The book introduces concepts — focal points, credible commitments, the value of communication — that explain why some negotiations naturally converge on win-win solutions and why others collapse into adversarial deadlock. Essential for understanding the structural conditions that make win-win feasible.
Win-Win — The shift from positional bargaining (fixed pie) to interest-based negotiation (expandable pie). Sustainable value creation requires structures where each party's self-interest creates value for the others.
Tension
Positive-sum Games
Win-win and positive-sum games describe the same structure from different angles. Positive-sum games are the theoretical category. Win-win is the practical application. The tension is subtle: not every positive-sum game automatically produces win-win outcomes. A game can be positive-sum in theory — the potential exists for both parties to gain — and still produce win-lose outcomes in practice if one party captures a disproportionate share of the created value. The tension highlights the difference between value creation and value distribution. Win-win requires both: the pie must expand (positive-sum) and the expansion must be shared (fair distribution). A monopolist who creates enormous consumer surplus but captures most of it through pricing power is playing a positive-sum game that does not feel win-win to the consumer.
Leads-to
[The Third Story](/mental-models/the-third-story)
The Third Story — the neutral narrative that both parties can accept — is the communication technique that enables win-win. In any disagreement, each party has their own story about what happened and who is right. The Third Story is the version a neutral observer would tell — acknowledging both perspectives without choosing sides. Using the Third Story to open a negotiation creates the psychological safety required for interest disclosure. When both parties feel heard and their perspectives validated, they are more willing to move from positions to interests — which is the foundational move that makes win-win possible. The Third Story is the on-ramp to win-win negotiation.
Leads-to
Nash [Equilibrium](/mental-models/equilibrium)
Win-win, when stable, is a Nash Equilibrium — a state where no party can improve their outcome by unilaterally changing their strategy. Amazon's marketplace is a Nash Equilibrium: sellers cannot improve their outcome by leaving (they lose access to customers), Amazon cannot improve its outcome by removing sellers (it loses selection), and customers cannot improve their outcome by leaving (they lose selection and price competition). Each participant's best strategy, given the others' strategies, is to remain in the arrangement. The Nash Equilibrium explains why successful win-win structures are self-enforcing — not because the parties choose to cooperate, but because cooperation is each party's individually optimal strategy.
