Negotiation foundations and decision preparation · Lesson 3

Interests, positions and diagnostic questions

Lesson objectives

  • Distinguish a stated position from an inferred interest and a verified constraint.
  • Ask questions that test an explanation without assuming motives.
  • Translate a party need into a reviewable performance criterion.

When one party says “I want a twelve-month contract” and the other says “I will commit for only three months,” you have heard two positions, not complete explanations. A position is the stated demand; an interest is why an outcome matters. A service provider might need a year to justify assigning a specialist. A customer might want three months to test quality before expanding. These are hypotheses until the parties confirm them. Use them to frame questions that reveal constraints rather than to claim you can read motives from a demand.

A blunt “Why are you insisting on a year?” may sound accusatory. Try “What does the longer period need to cover for you?” and follow with “Would a guaranteed volume during a shorter period change that need?” Ask the customer, “What would you need to learn by the end of three months?” and “What decision would that evidence support?” Listening includes paraphrasing and inviting correction: “I hear that staffing needs predictable work, rather than that the number twelve has value in itself. Is that accurate?” The provider might correct your hypothesis entirely.

Keep three columns in your notes: “stated by the party,” “inference to test,” and “verified constraint.” The provider's planned training is stated in the case; needing exactly twelve months is not established. The customer's wish to measure response is stated; a personal lack of trust in the provider is speculation. This distinction matters when relationships become tense: you can take risk concerns seriously without assigning negative motives. If the other side declines to reveal private commercial data, ask for a performance condition that both can verify instead of demanding confidential figures.

Lesson summary

A position is a demand; an interest explains why it matters. Test explanations with questions and paraphrases rather than treating inferences as facts.
