# Differentiation Proof Interview Plan

Canonical page: https://waitlist.crany.ai/marketing-templates/differentiation-proof-interview

By Tangenix. Published 2026-10-24. Category: Positioning.

Investigate whether a claimed software distinction mattered in a recent buying decision, using concrete experiences and disconfirming evidence.

## Task

Test the buyer relevance of one claimed distinction through a recent decision story.

## When to use

Use this when your team can demonstrate a capability difference but does not know whether it changes a buyer’s choice. Recruit someone with a recent relevant decision, including people who chose an alternative.

## Choose another approach when

You want participants to praise a feature, need a representative market estimate, or plan to disguise a demo or sales follow-up as neutral customer research.

## Inputs

- One precise differentiation hypothesis and the evidence for the capability itself.
- A voluntary participant with recent experience choosing how to handle the target task.
- A note-taking agreement and a way to separate the participant’s account from your interpretation.

## Template

    Hypothesis to investigate: [buyer situation + distinction + expected consequence]
    What would weaken this hypothesis: [a plausible contrary account]
    Opening: I want to understand a recent decision, not persuade you to choose our product.
    Recent-event prompts:
    - Tell me about the last time you chose how to handle [task].
    - What set the search or decision in motion?
    - What options did you actually consider, including keeping the old process?
    - What mattered when you chose, and what tradeoffs did you accept?
    - Where, if anywhere, did [neutral capability description] enter that decision?
    - What happened after you used the chosen approach?
    Account / supporting context: [faithful notes, no invented quotes]
    Contrary evidence and missing evidence: [record both]
    Interpretation: relevant in this situation / absent / unresolved
    Next check: [observation or task attempt; no automatic demand claim]

## Illustrative example

This is not a Crany customer result. Replace example details with verified facts.

    Fictional example: a founder believes a login-free client preview is the reason designers would switch tools. A participant describes a recent handoff and explains that a client’s procurement rules required an authenticated portal.
    The founder records this as evidence against the hypothesis in that situation. They do not rewrite the story as “customers demand login-free access” or argue that the participant is wrong. Another participant’s different circumstances may produce a different account.
    The next research question concerns which client constraints make the preview useful. A claimed technical difference remains separate from evidence that a specific buyer values it.

## How to use

1. Write the hypothesis and a disconfirming possibility before the conversation.
2. Follow the recent decision story before introducing a neutral description of the distinction.
3. Preserve contrary accounts and choose an observation that can check the strongest remaining assumption.

## Checks

- The prompts do not describe the capability as better, essential or unique.
- A participant is free to decline and is not surprised by a sales pitch.
- Stated preference, a remembered choice and an observed task outcome remain separate evidence types.

## What to measure

Record where the distinction entered an actual decision, where it did not and what context differs. Use qualitative patterns to refine a hypothesis; do not turn a small interview set into a market percentage or treat verbal enthusiasm as buying behavior.
