Scenario: A facial recognition AI at a major retailer produced wildly inaccurate results after a UI redesign on input cameras.

Root Cause:

  • Model drift + no post-deployment testing

  • Cameras fed grainier images, but the model wasn’t retrained

Mitigation:

  • Reintroduced regular input quality checks

  • Added model drift alerts

  • Re-trained with new data pipeline

📌 Trust was regained — after almost being lost.
