Your question is Production Model Monitoring. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you monitor a model’s performance after it has been deployed to production?
Explain which service, data-quality, model-quality, and business metrics you would track. Discuss how you would detect drift, handle delayed or missing labels, distinguish model degradation from traffic changes, and trigger investigation, rollback, or retraining.
