Before-and-after comparison
Before-and-after comparison is meaningful when the starting point, the change, and the way to judge it are clear.
Before-and-after comparison is meaningful when the working path stays comparable and the change can be observed. This page focuses on differences in understanding, time, ownership, and decision quality—not visual effect alone.
Work
Rather than decorative comparison, we show change in readability, action path, data quality, state control, or maintenance. Every change should answer a real source of friction.
Measure change in the same work path
A comparison should connect the observable change to the starting problem and a defined measure.
