Persuading a peer with evidence
In a fictional student project, I recommended testing the data import before building the final charts. I did not control the schedule. A teammate was concerned the test would delay design, so I showed two fictional malformed records from our draft file and proposed a 30-minute sample check rather than a full review. The group agreed to the limited test, found one date-format issue, and corrected it before charting. The evidence supports agreement to that test, not that I changed everyone's general approach.
