The place in the Werkbank where you show what has changed through your work with AI.
An impact entry has a before and an after as a number with a unit, exactly one currency (time, money, quality or reach), the label measured or estimated, and a date. You record the before before you change anything. Nothing is invented: if a value is missing, the entry stays without a comparison.
Example from Module 6
Before value: number of steps started by hand today. After value: number of steps with a set trigger.
Module 6: “Measuring impact: before and after”. In the Werkbank course room, with sign-in.
