Unit 12: Lifecycle Management & Change Tracking for AI Systems
Scenario: An HR tool used for employee promotion recommendations is retrained quarterly.
What went wrong:
A minor code update changed the scoring logic
Promotions skewed significantly by department
No documentation of the change existed
Fix:

Added rollback plan + retraining alerts
Reassessed and updated documentation
📌 Transparency saved the org from a public and legal headache.
