A community garden used to announce watering times only on a board at its entrance. Volunteers who lived far away sometimes arrived after another group had already watered the plants. The garden then added a shared online log. Volunteers recorded the time, area, and amount of water after each visit. The log did not water the plants or decide whether soil was dry; it helped the next volunteer see what had already been done. After a month, the team added a note field because numbers alone could not describe signs of disease or storm damage.

At first, a museum asked visitors to rate an exhibit immediately after viewing it. Later, researchers emailed the same visitors a week afterward and asked them to explain the exhibit's main comparison. Immediate ratings were generally high, but some visitors who had given high ratings could no longer explain the comparison. The museum therefore kept the rating question but stopped treating it as the only measure of understanding.

A transit agency compared two kinds of delay reports. Automatic sensors provided precise times but sometimes failed to record why a bus had stopped. Driver notes were less uniform in wording, yet they often identified causes such as road construction or a medical emergency. The agency combined the two sources, matching times before comparing explanations. It did not assume that agreement proved completeness; both sources could miss a delay that occurred outside their coverage.

A school newsletter first summarized survey results with percentages alone. Editors later added the number of respondents beside each percentage. This did not change the responses, but it helped readers distinguish a result based on twenty students from one based on two hundred.
