Explaining technical information
In a fictional internship, I needed to explain a data-definition change to a coordinator who used the report but did not maintain the query. I confirmed which totals they relied on, defined the old and new inclusion rule in one sentence each, and showed one fictional record affected by the change. I asked them to explain which total they would use for the next report, and their answer matched the approved definition. My result was verified understanding of that rule, not proof that I made the whole system simple.
