Design a cross-functional proof-of-value (PoV) process to rapidly validate ML product ideas across multiple teams with minimal engineering overhead. Describe steps from hypothesis to measurement, required minimal infra (feature flags, shadowing), success criteria, timeboxes, and how to hand off a successful PoV to production engineering.

A deployed vision model has started showing performance degradation. Outline an end-to-end strategy—technical and organizational—to detect drift early, triage root causes (data distribution shift, label noise, latency changes), and mitigate with retraining, data augmentation, or fallbacks. Include monitoring signals, alert thresholds, and playbook steps for on-call engineers and product owners.
