Guide: https://showmeyoursaas.com/articles/product-market-fit/

PURPOSE
Learn which audience depends on the product, for which recurring job, and why.
This is a research aid, not a validated prediction of commercial success.

CORE QUESTION AND ATTRIBUTION
Rahul Vohra's first-person Superhuman account describes Sean Ellis's method:
https://review.firstround.com/how-superhuman-built-an-engine-to-find-product-market-fit/
Our guide reproduces that method's core item. Use its exact wording and options
consistently if tracking that method and discussing its familiar heuristic.

The following is OUR ORIGINAL ADAPTED QUESTION, not the exact Ellis item:
What impact would losing access to [product] have on your work?
Options: Very disappointed / Somewhat disappointed / Not disappointed
Changing a question can change responses. Do not compare this adaptation with
the original method's benchmark as if the instruments were identical.

ORIGINAL FOLLOW-UP QUESTIONS — SELECT ONLY WHAT THE DECISION REQUIRES
1. What job were you trying to complete the last time you used the product?
2. What result did you get, and what remained unfinished?
3. What would you use or do instead if this product disappeared?
4. Which part of the workflow saves you the most effort, and why?
5. What nearly stopped you from completing that job?
6. Who else has this same problem, and how is their situation similar?
7. Optional: may we contact you about this response?

INVITATION DRAFT — ADAPT TO YOUR RELATIONSHIP WITH THE CUSTOMER
We are reviewing how well [product] supports [job]. We welcome critical feedback
as well as positive experiences. The short survey is optional. Please do not
include client records or other sensitive information. Follow-up contact is
optional and separate from receiving product marketing.

RESPONSE WORKSHEET
Eligible accounts invited:
Eligible respondents answering the core item:
Core-item skips:
Strongest disappointment responses:
Score = strongest responses / eligible core-item respondents × 100
Response rate = eligible core-item respondents / eligible accounts invited × 100
Preselected segment and its counts:
Known differences between respondents and nonrespondents:

FICTIONAL ARITHMETIC EXAMPLE — NOT SHOWMEYOURSAAS RESULTS
80 invited; 20 answer the core item; 9 choose the strongest response.
Score = 9 / 20 × 100 = 45% of respondents.
Response rate = 20 / 80 × 100 = 25%.
One changed answer moves the score by 5 percentage points.
60 nonrespondents' views remain unknown. A threshold does not establish fit.

EVIDENCE REVIEW

Churn and reasons for leaving:
Delivery cost and unrecorded founder assistance:
Contradictory evidence:
Narrow audience receiving the clearest value:
