Glossary
Updated
A proactive discipline encompassing code reviews, data-validation tests, model-evaluation pipelines, and compliance checkpoints integrated into the development lifecycle. QA frameworks include automated unit and integration tests, standard data-quality metrics, bias-detection scans, and sign-off gates before deployment. Continuous QA ensures that every change (data update or code tweak) passes rigorous checks, preventing regressions in performance or compliance.
Example
A financial-services firm implements QA by enforcing pre-commit hooks that run data‐schema validations and bias‐scan scripts. Every model commit triggers automated tests for accuracy thresholds and fairness metrics; failures block merges until issues are resolved, ensuring only compliant, high‐quality changes reach production.
