Optimizing for the wrong objective often causes this.
Offline metrics may not reflect real business constraints or costs. A model can be more accurate but less useful operationally.
Revisit evaluation metrics and ensure they align with real-world impact. Incorporate business-aware metrics where possible.
Also check for changes in prediction thresholds or decision logic.
Common mistakes include:
Over-optimizing technical metrics
Ignoring feedback loops
Deploying without business validation
The takeaway is that models serve outcomes, not leaderboards
