Operational discipline separates experimental systems from infrastructure. You'll establish governance workflows: model promotion gates with two-person review, weekly chaos testing, and biweekly cost-performance reviews. Learn to implement the Metrics Ladder for automated drift detection and correction.

Finally, internalize lessons from enterprise failures and successes. Analyze anti-patterns like uncalibrated confidence and untested fallbacks through real case studies. Establish continuous improvement loops that measure, diagnose, and correct model performance, transforming reactive firefighting into proactive reliability engineering.
