Production Monitoring is the continuous observation and analysis of ML models in real-world environments to ensure they maintain expected performance, detect issues early, and trigger interventions when needed.
Critical Reasons:
• Model Drift - Data distributions change over time
• Performance Degradation - Accuracy may decline
• Business Impact - Poor predictions affect users
• Compliance - Regulatory requirements
⚠️ Reality Check
A model that performs at 95% accuracy during development might drop to 70% in production within months if not properly monitored and maintained!
