If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

What did you intend to test during the trial?
Which task could you complete?
What remained untested?
What information would help you decide on continued use?
Which limitation affected your evaluation?

Author notes / illustrative keys where applicable:
1. Identify the intended evaluation task before deciding whether a trial was useful.
2. Separate a successful task from simply visiting or configuring the product.
3. Record what was not tested so absence of evidence is not treated as a negative verdict.
4. Find decision information that remains missing rather than assuming an extension is always the answer.
5. Distinguish a plan restriction, time limit, and product gap when reviewing a limitation's impact.
