Assess whether the model score is a false positive from a life event (1e012a)

Situation

Payments-risk officer in a credit-card issuer during a holiday-authorization spike has one working extract — check-kiting multi-bank float map — after a customer calling to reverse a 'authorized' card charge. Payments-risk officer in a credit-card issuer during a holiday-authorization spike has check-kiting multi-bank float map after a customer calling to reverse a 'authorized' card charge. If that extract cannot support the model score is, the honest Fraud Detection Claims and Benefits Fraud output is hold.

Decision

Payments-risk officer in a credit-card issuer during a holiday-authorization spike must choose Remove access or reverse the item / Temporary compensating control / Approve a documented exception / Hold using check-kiting multi-bank float map after a customer calling to reverse a 'authorized' card charge.

Hypotheses to test

• A customer calling to reverse a 'authorized' card charge is noise around an already-controlled Claims and Benefits Fraud process in a credit-card issuer during a holiday-authorization spike, given check-kiting multi-bank float map.
• A customer calling to reverse a 'authorized' card charge is the event in check-kiting multi-bank float map that forces Remove access or reverse the item for payments-risk officer under Fraud Detection.
• Check-kiting multi-bank float map shows a one-file miss after a customer calling to reverse a 'authorized' card charge, not a Claims and Benefits Fraud program failure.
• Check-kiting multi-bank float map cannot decide the model score is yet after a customer calling to reverse a 'authorized' card charge; hold is the only Fraud Detection close a credit-card issuer during a holiday-authorization spike can defend.

Analysis required

• Check mule or round-trip markers in check-kiting multi-bank float map.
• Map typology and hold authority payments-risk officer actually has in a credit-card issuer during a holiday-authorization spike.
• Trace funds, counterparties, and reversals in check-kiting multi-bank float map through the window opened by a customer calling to reverse a 'authorized' card charge.
• For this Fraud Detection Claims and Benefits Fraud file, read check-kiting multi-bank float map against a customer calling to reverse a 'authorized' card charge and write the one fact that would move the model score is for payments-risk officer.
