Problem

Scenario

You've shipped a model and it is now being used in a live product workflow. The team wants a clear way to judge whether the model is actually successful after deployment, not just whether it looked good offline.

Question

What Success Means

  • Model quality in production
  • Business KPI impact
  • Calibration of predicted scores
  • Threshold performance in the live workflow
  • Incremental lift versus baseline
