Financial decisions have different legal and operational requirements, and a prediction is not the same as a permitted or fair decision. Define the product, consumer impact, and evidence needed before deployment.

Viktige takeaways

• Define decision context and error costs.
• Log inputs, versions, thresholds, and human actions.
• Make explanations reflect the real decision process.

Start with the outcome and the decision-maker. A model that flags transactions for investigation differs from one that declines a credit application. Record the data available at decision time, the target label, and the consequences of false positives and false negatives. Historical decisions can encode past selection and may not be an appropriate target. Keep an audit trail for data, features, model version, threshold, and human action. Test drift, missing values, and unusual account behavior. A fraud detector that blocks legitimate customers can create costs that do not appear in an accuracy score. Monitor review queues and complaint patterns after release. For credit decisions, the CFPB states that complex algorithms do not remove obligations to provide specific adverse-action reasons. An explanation should identify actual factors used by the decision process, not a generic feature list invented after the fact. Obtain current legal advice for the jurisdiction and product. Protect account information and restrict automated actions. Require confirmation for transfers, account changes, or other high-impact outcomes, and verify the resulting state after execution.

1. Imagine a model gives an application a risk score of 0.72.
2. A policy sets a threshold, a reviewer checks documentation, and a notice explains the specific reasons for an adverse decision.
3. Evaluate the model, policy, review, and notice separately rather than treating the score as the decision itself.

This invented workflow separates prediction from regulated action.
