Your question is Monitor Production Model Degradation. 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).
You are responsible for a model that is already live in production, and the business wants to know when it starts to drift or degrade. The team needs a practical monitoring and alerting plan, not a one-time offline evaluation.
How would you monitor and alert on model degradation in a production environment?
