Make them solve the implementation for you
Ask "What does success look like?" and "How do we get there?" to make the other side do the planning.
Key takeaways
- What it is: Ask "What does success look like?" and "How do we get there?" to make the other side do the planning.
- Why it works: When the other party names what success looks like and outlines how to get there, they take psychological ownership of the solution. Ownership commitment is far stronger than compliance: they will work to make the plan succeed because it is now theirs. The process also surfaces hidden constraints and reveals real interests, which is more useful intelligence than any concession.
- Evidence: Plausible mechanism, limited direct outcome data.
- Avoid: Taking over the planning once you get the information you wanted — the point is to let them author the solution, not to harvest their input and then impose yours.
Why it works
When the other party names what success looks like and outlines how to get there, they take psychological ownership of the solution. Ownership commitment is far stronger than compliance: they will work to make the plan succeed because it is now theirs. The process also surfaces hidden constraints and reveals real interests, which is more useful intelligence than any concession.
How to do it
- 1After reaching rough agreement on a goal, ask: "What does success look like on your end?"
- 2Then ask: "How do we make sure we get there?"
- 3Reflect their answers back to confirm understanding, then let them elaborate further.
- 4Take notes — their answers are a map of what they actually need, often different from what they demanded.
What the evidence says
MechanisticThe ownership effect — greater commitment to self-generated solutions — is supported by research on self-determination and on IKEA-effect-style findings: effort and authorship increase perceived value and commitment to outcomes.
Honest caveat: The IKEA effect study is about assembly and effort; extrapolating to negotiation planning is principled but the direct application is practitioner inference rather than a studied outcome.

Common mistake
Taking over the planning once you get the information you wanted — the point is to let them author the solution, not to harvest their input and then impose yours.
IX Coach identifies which questions in your negotiation should be left for the other party to answer rather than solved in advance, preserving their ownership of the outcome.
