CAS D'USAGE IA
Échantillonnage d'Audit Augmenté par l'IA
Le machine learning identifie les transactions à plus haut risque pour concentrer les tests d'audit.
De quoi il s'agit
Elle est particulièrement efficace pour les grands volumes de transactions, où la revue manuelle exhaustive est impossible.
Données nécessaires
Historical transaction records with labels or flags indicating past audit exceptions, anomalies, or fraud findings, covering at least two to three audit cycles.
Systèmes requis
- erp
- data warehouse
Pourquoi ça marche
- Involve experienced audit managers to validate model risk features and ensure outputs align with professional judgement.
- Start with a single high-volume client engagement as a pilot before rolling out across the portfolio.
- Maintain explainability by using interpretable models or SHAP values so auditors can justify sampling decisions.
- Establish a feedback loop where audit findings from each cycle are fed back to retrain and improve the model.
Comment ça rate
- Insufficient labelled historical exceptions makes model training unreliable and leads to poor risk stratification.
- Auditors distrust the model outputs and revert to traditional sampling, negating efficiency gains.
- Model trained on past exceptions misses novel or emerging fraud patterns not represented in historical data.
- Client ERP data is inconsistent or poorly structured, requiring excessive cleaning that delays deployment.
Quand NE PAS faire ça
Do not deploy this if your client transaction data is fragmented across multiple incompatible legacy systems with no centralised data layer, the integration cost will exceed the audit efficiency gains.
