The flat line that hid a regional fire

The flat line that hid a regional fire
It was a Tuesday when a beverage brand's global sentiment held steady at 71% positive, and leadership relaxed. One market told a different story. Segmented by geography, German sentiment had quietly dropped 23pts over three weeks on a reformulation backlash, while a surge of positivity in Brazil masked it in the global average.

The blended number was a thermostat reading the average of a freezer and an oven. Both extremes were invisible.

They rebuilt reporting to flag any single market moving more than 10pts, regardless of the global figure. The German issue, caught a week earlier next time, was contained before national press picked it up.

The tradeoff: geo-segmentation needed reliable location data, missing on 30% of mentions, so the splits were directional, not exact.

The takeaway: a global average is where regional crises go to hide. Segment first, average last.
