Measure change in the same work path
Keep baseline, change, and judgement measure on one level.
- Starting point and primary friction
- Design or technical decision made
- How the change can be observed
Before-and-after comparison
Compare the change in the same working path.
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.

To see the logic of an improvement
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.
