Fraud signal audit, taught as desk craft.

Schema Designlab treats your fraud signal audit app as a living record: every alert should state what it claims, what evidence it needs, and when a human must still decide.

What we mean by audit

Not a once-a-year binder. An audit is a recurring review of signal coverage, owner health, false-positive debt, and change control — captured so someone outside your team can follow the reasoning.

Teams across the United Kingdom use our drills to prepare for partner reviews, internal model governance, and the awkward question: “Why is this still firing?”

Four artefacts we insist on

  • Signal inventory

    A complete list with owners, proof claims, and last review date — exported from or mapped to your fraud signal audit app.

  • Failure-mode cards

    Short write-ups of how each rule fails open or fails closed, including customer-impact notes.

  • Desk finding pack

    Evidence, recommendation, residual risk, and open questions in a format peers can challenge.

  • Change defence script

    Language for explaining retirements and tightenings to product and compliance partners.
