Customer Commitment Validation
Use this skill after a product, sales, partnership, investor, or customer
conversation where the team needs to decide whether the meeting created real
progress. The core test is what the other person gave up: time, reputation, or
money.
Source Traceability
Primary source: The Mom Test by Rob Fitzpatrick, especially chapters 5 and 8.
Guidance is paraphrased for this MIT repo; authoring notes used converted EPUB

High
Compliments, vague "keep me posted" replies, and future-tense buying promises
are not commitments.
An advancement must move the real-world funnel to a specific next decision or
action. A next step without an owner, date, or customer-side effort is usually
weak interest.
Review Workflow
Restate the meeting context and what the team hoped would happen next.
Classify the outcome as commitment, advancement, rejection, weak interest, or
bad data.
Identify what the other person gave up, if anything.
If the outcome is fuzzy, propose a concrete next ask that creates a decision.
If there was rejection, preserve the learning and decide whether it changes
the product, segment, positioning, or sales path.
If there was commitment, define the owner, date, success criteria, and follow
up.
