Understanding Interests

The Key to Creative Agreements

The most important concept in negotiation: focus on interests, not positions.

Positions are what people say they want. Interests are why they want it.

Understanding this distinction unlocks negotiations that seem stuck.

Positions vs. Interests

The Classic Example

Two siblings fight over an orange. Each takes a position: "I want the orange."

A positional solution: cut it in half. Each gets half an orange.

But what were their interests? One wanted the peel for baking. One wanted the juice for drinking.

If they'd explored interests, each could have gotten 100% of what they needed.

In Real Negotiations

Position: "I need a 15% salary increase." Interests: Feeling valued, financial security, fairness relative to peers, covering increased expenses.

Position: "We can only offer 8%." Interests: Budget constraints, internal equity, retention, appearing reasonable.

When you understand interests, creative solutions emerge: a smaller raise plus signing bonus, equity, flexible work, title change, development budget.

Types of Interests

Substantive Interests

The tangible outcomes: money, terms, deliverables, time.

Procedural Interests

How the process works: being heard, having input, fair process.

Relational Interests

The relationship: trust, respect, ongoing collaboration, reputation.

Identity Interests

How people see themselves: being seen as competent, fair, successful.

All four types matter. Sometimes procedural or identity interests matter more than substantive ones.

Uncovering Interests

Ask Why

The simplest technique. When they state a position, ask why.

"I need delivery by March 1." "Help me understand — why is March 1 important?" "We have a product launch scheduled."

Now you know the real interest (supporting the launch), and you can explore whether March 1 is flexible if the launch support can be achieved another way.

Ask "Why Not?"

When they reject your proposal, ask why not.

"We can't offer that." "What concerns does it raise for you?"

This reveals the interests behind their resistance.

Ask "What If?"

Hypotheticals can surface interests without commitment.

"What if we could guarantee March delivery but it cost 10% more?"

Their response reveals how they trade off interests.

Share Yours First

Sometimes sharing your interests invites them to share theirs.

"What matters most to me is reliability — I need to know the work will be done right. What matters most to you?"

Listen for Interests

People often hint at interests without stating them directly.

"That's a lot of money..." (Interest: budget pressure) "My boss would never approve that..." (Interest: internal credibility) "We've always done it this way..." (Interest: predictability, risk aversion)

Organizing Interests

List Interests, Not Positions

Create a list of interests for both sides:

Prioritize

Which interests are essential? Which are important but flexible? Which would be nice but aren't critical?

Find Shared Interests

Often both sides share some interests:

• We both want a deal that works
• We both want a productive relationship
• We both want to avoid legal disputes
• We both want efficient process

Shared interests are foundation for collaboration.

Find Different Interests

Different interests create trading opportunities:

• You value flexibility, they value commitment
• You value speed, they value quality
• You value cash, they value relationships

Differences let you trade what matters less to you for what matters more.

Common Interest Categories

In Employment Negotiations

Employee: Compensation, growth, flexibility, security, recognition, autonomy Employer: Performance, retention, budget, team fit, predictability, reputation

In Sales Negotiations

Buyer: Price, quality, timing, support, risk reduction Seller: Revenue, margin, volume, relationship, reference value

In Partnership Negotiations

Both: Success of venture, risk allocation, control, exit options, efficiency

Interest-Based Problem Solving

Step 1: Identify Interests

Make lists. Ask questions. Share yours. Understand theirs.

Step 2: Find Common Ground

What do you both want? Start from shared interests.

Step 3: Explore Trades

Where do your priorities differ? Can you exchange what matters less to you for what matters more?

Step 4: Generate Options

Brainstorm solutions that address both sides' key interests. Don't evaluate yet — generate freely.

Step 5: Evaluate Options

Which options best satisfy both sides' interests? Use objective criteria where possible.

Step 6: Reach Agreement

Select the option that maximizes joint value and satisfies essential interests.

When They Won't Share Interests

Sometimes the other side won't discuss interests openly. You can:

Infer from behavior: What are they asking for? What do they resist? What do they react strongly to?

Hypothesize: "It sounds like timeline might be important to you..."

Share yours anyway: Modeling openness sometimes invites reciprocity.

Ask different questions: "What would make this deal a success for you?"

AI Prompt: Interest Analysis

Help me analyze interests in my negotiation.

The situation: [Describe]
My stated position: [What I'm asking for]
Their stated position: [What they're saying]

Help me:
1. Identify my underlying interests (why I want what I want)
2. Hypothesize their underlying interests
3. Find potential shared interests
4. Identify different interests that create trading opportunities
5. Generate options that address both sides' key interests
