Negotiation.

The framework

1. 01

   Widen the list past the number you keep arguing about.

   Write out the full list of issues in the deal rather than the two you've been arguing over: price, timing, term, scope, payment schedule, exclusivity, who does the work, who carries the risk, what happens when it goes wrong. Then go down the list and mark each one opposed, possibly identical, or never tested, and accept that most of those marks are guesses. A negotiation held on a single issue can only be split, because there is nothing inside one number to find. The list is what makes the next move possible; the marks tell you where to look first.

2. 02

   The fixed pie forms in the first ten minutes.

   Thompson and Hastie found the fixed-pie belief forms early and then holds, which makes the most consequential stretch of a negotiation the part you've been treating as warm-up. You spend those minutes laying out your case, and the case is assembled entirely from your own side's information. Spend them instead on questions about sequence and priority: what matters most here, what would you settle first, what's the part of this you can't go home without. You won't get a full answer. You'll get enough to know which of your assumptions to drop before the numbers start.

3. 03

   Stop paying for agreement you already had.

   The incompatibility error is the expensive half of this. You offer something as a gesture — the longer term, the earlier start, the named contact — and it turns out they wanted it that way as well, so you've bought with real money a thing you'd have been given. Before you offer anything as goodwill, ask whether they might already prefer it, and where you suspect they do, put it forward as a shared position instead of a concession. Goodwill spent on an issue you already agreed on is a discount nobody asked you for.

4. 04

   Your read of them is a claim worth scoring.

   When the deal closes, take the sheet where you marked each issue and write down what turned out to be true. Negotiators don't get better at reading counterparties by doing more negotiations; they get better by checking. Keep the sheets in one place and a pattern surfaces inside a year: you consistently overestimate how much they care about price, or you consistently miss the internal approval that governs their timing. That pattern is the most valuable thing you carry into the next deal, and you can only have it if the guess went on paper first.
