Implementation Guidance

Adopt AI design patterns embedding fairness constraints, privacy preservation, and explainability mechanisms. Implement MLOps pipelines with automated testing for model drift, bias, and adversarial robustness. Require multi-stage deployment (canary, blue-green) for high-risk systems with defined rollback criteria. Establish change advisory board review for significant AI system modifications with mandatory regression testing.
