The "Mom Test"
Interview Protocol.
1. The Executive Summary
The "Mom Test" Interview Protocol is a customer discovery framework derived from the principle that you should never ask anyone if your business is a "good idea." Why? Because everyone (especially your mom) will lie to you to protect your feelings.
The Golden Rule: If you mention your idea during the first 15 minutes of the call, you have failed the protocol. You are there to excavate pain, not sell a cure.
2. The Outcome
By executing this protocol across 5 subjects, you will possess:
- The "Bleeding Neck" Verification.
- The "Workaround" Map (Competitors).
- The Price Anchor (Current Spend).
- Zero False Positives.
3. The Prerequisites
- Target List:5 Strangers (ICP). No friends/family.
- Mindset:Detective, not Salesperson.
- The Mantra:Facts > Opinions.
4. The Algorithm
The Setup (The "Non-Meeting")
Goal: Lower their guard. Avoid performance anxiety.
Rules of Engagement
Goal: Maintain protocol discipline.
Rule 1: No Pitching
The moment you pitch, they start lying (complimenting).
Rule 2: Past > Future
Allowed: "How did you check receipts last week?" Forbidden: "Would you use..."
Rule 3: The 80/20 Rule
They talk 80%. You talk 20%.
The Question Architecture
Goal: Drill down to root cause.
"Walk me through how you currently handle [Task]?"
"You mentioned that was annoying. Why? Who gets yelled at if it fails?"
"What are you doing to fix this right now? Have you looked for tools?"
"How much do those workarounds cost you?"
The Translation
Goal: Filter Signal from Noise.
| The User Says... | Translation | Status |
|---|---|---|
| "That sounds like a great idea!" | "I am being polite." | Noise |
| "I would buy that." | "I'm lying about the future." | Noise |
| "I tried Tool Z but it sucked." | "I have active pain." | Signal |
| "I pay a VA $20/hr to do this." | "I have a budget." | Jackpot |

"Is it hard to do X?" You are feeding the answer. Ask open questions.
Feature Auditing
Listing features to check reactions. You are testing imagination, not reality.
Happy Ears
Hearing what you want. Be a pessimist. Unless they scream, it's a no.
