How do I set up a fix and measure whether it works?

On the problem's page under “Fixes”. You describe the structural change, the reduction at which it counts as a success and over how many days it's measured. Approving records the decision in Peak Log, and “Start measurement” with the implementation date begins the comparison with the period before.

1. 01Open the problem → Fixes: enter the change, type, expected effect, “Success from reduction (%)” and “Measure over (days)”, then click “Propose fix”.
2. 02Click “Approve”.
3. 03Choose “Implemented on” and click “Start measurement”.
4. 04After the measurement window: “Record result”. If the fix does harm, “Roll back”.
