Agree what is being examined.
State the question in terms that another person can review. “The export works” leaves several possibilities open. A more specific question might concern whether selected fields appear in the expected order when a report is generated from an invented sample file.
Define the expected observation before looking at the result. This reduces the temptation to change the meaning of success after the demonstration. It also makes it easier to notice when an apparently positive result has answered a different question.
Keep an understandable record.
A compact record can identify the sample used, relevant settings, the action taken, and the result observed. Note unexpected behavior as well as the expected outcome. Another person should be able to understand the account without reconstructing the entire conversation.
Separate observations from interpretations. A file appearing in a selected folder is an observation. A claim that an application will always preserve every report is a much broader interpretation. The evidence needed for that claim would depend on additional conditions and tests.
Make uncertainty part of the handover.
A review should describe what remains unexamined and why that matters to the next decision. A small sample, simulated dependency, or limited environment may be appropriate for exploration, provided its limits are visible.
The conclusion can recommend a revision, another question, or a discussion about implementation. It can also identify an issue that prevents further progress. Clear boundaries help the recipient use the research responsibly instead of treating a polished document as certainty.
