Case Study: Churn Model, End-to-End MLOps

Follow one churn-prediction model from a notebook to a governed, monitored, self-healing production system

30 min read 18 views

Model interview answer that threads a single churn-prediction model through the full MLOps lifecycle: notebook prototype, CI tests and data-validation gates, experiment tracking and registry promotion, a canary release, a production drift alert, a safely-gated automated retrain, and a governance review before the retrained model ships. Each stage names the specific tool category and the specific failure it prevents.
