Do Not Treat a QA Pass as Proof That Users Can Do the Job
The QA versus UAT Matrix
Companion to You Are Not the User · Updated 2026-09-29
Use this when a team is treating a QA pass as proof that users can do the job, or scheduling UAT that is really a second round of QA. Worked in “‘We Tested It’ Means Almost Nothing.”
The QA versus UAT Matrix, one line per dimension, filled in for your own release.
| Dimension | QA | UAT |
|---|---|---|
| Question asked | ||
| Who performs it | ||
| Tested against | ||
| Data used | ||
| What “pass” means | ||
| What a pass can’t prove |
If the two columns come out nearly identical in the “Who performs it” and “Data used” rows, the team ran QA twice and called the second one UAT.
