Create a structured interview script that surfaces real insights, not just opinions. Follows "The Mom Test" principles — ask about their life, not your idea.
Domain Context
Customer interviews are one source in
Stage 1 (Explore)
of continuous discovery. Other sources: stakeholder interviews, usage analytics, data analytics, surveys, market trends, SEO/SEM analysis. The PM needs direct access to users, stakeholders, engineers, and designers — "without proxies." The
Product Trio
(PM + Designer + Engineer — Teresa Torres) should work together on discovery, not just the PM alone.
Context
You are preparing a customer interview script for research on
$ARGUMENTS
.
If the user provides files (personas, hypothesis lists, product briefs, or previous interview notes), read them first.
Instructions
Clarify research objectives
:
What specific questions does the team need answered?
What decisions will this research inform?
What assumptions need validation?
Create the interview script
with these sections:
Opening (2-3 min)
Introduce yourself and the purpose (learning, not selling)
Set expectations: "There are no right or wrong answers. We're here to learn from your experience."
Ask permission to record (if applicable)
Confirm time available
Warm-Up: Context & Background (5 min)
"Tell me about your role and what a typical day/week looks like."
"How long have you been doing [activity related to the product area]?"
Goal: Build rapport and understand their context
Core Exploration: Jobs to Be Done (15-20 min)
Current situation and behavior
(past tense, specific instances):
"Walk me through the last time you [did the thing we're exploring]. What happened?"
"What tools or methods did you use?"
"How long did it take? Who else was involved?"
Pain points and frustrations
(observe, don't lead):
"What was the hardest part about that?"
"If you could wave a magic wand, what would change?"
"What have you tried to solve this? What happened?"
Desired outcomes
(their words, not yours):
"What does 'good' look like for you in this area?"
"How would you know if this was working well?"
Willingness to pay / priority
(skin in the game):
"How much time/money do you currently spend on this?"
"Have you looked for a better solution? What did you find?"
"What would you give up to have this solved?"
Probing Techniques
Use these when you hit an interesting thread:
"Tell me more about that"
— opens up any topic
"Why?"
(asked gently, 2-3 times) — gets to root causes
"Can you give me a specific example?"
— moves from opinions to facts
"What happened next?"
— follows the story
"How did that make you feel?"
— captures emotional intensity
The Mom Test Rules
Ask about
their life
, not your idea
Ask about
the past
, not the future ("Would you use X?" is useless)
Talk less, listen more
— aim for 80/20 split
Never pitch
during the interview
Look for
strong emotions
— they signal real pain or delight
Compliments are noise
— "That sounds cool!" tells you nothing
Wrap-Up (3-5 min)
"Is there anything I didn't ask that you think is important?"
"Who else should I talk to about this?"
Thank them for their time
Share next steps (if any)
Customize the script
Adapt questions to the specific product area, persona, and research objectives. Add or remove sections based on the interview length available.
Include a note-taking template
:
Participant: [Name / ID]
Date: [Date]
Key Jobs: [What they're trying to accomplish]
Current Solution: [What they use today]
Biggest Pain: [Their #1 frustration]
Desired Outcome: [What success looks like]
Willingness to Pay: [How much they invest / would invest]
Surprise Finding: [Something unexpected]
Follow-up: [Next steps]
Save as markdown. Include both the script and the note-taking template.
