Big-number slide
Use one decision-relevant metric, its unit, time period, denominator and source. Example: “18 of 24 teams completed the four-week pilot.” Add the source and the limitation: completion does not establish renewal demand.
In Lumen, give the metric and context in the outline, then inspect the generated layout. Avoid a giant “75%” with no population or reporting period. If you need to compare several series, use a chart instead.
