Statistical anomaly detection separates real manufacturing defects from dealer-side abuse — and flags emerging defect patterns weeks before they hit the news cycle.
The challenge
Every dealer categorises failures differently. Free-text fault codes are inconsistent. Claim intake tools were built for accounting, not engineering. Real defect signals hide inside a mountain of misfiled tickets.
The quality team spots failure patterns only when the failure count is already big. By then the defect is on 40,000 units, and the design department gets the news through a headline, not a report.
A subset of repair shops routinely inflate claims. Without statistical separation of legitimate defects from claim inflation, the reserves budget bleeds every quarter.
The approach
A concrete solution pattern our SAP BTP architects would design and deliver for you. Not a slideware pitch — an implementable reference architecture.
Warranty claims from S/4HANA join with build-configuration data (which parts, which supplier batch, which plant) and vehicle telematics when available. All in HANA Cloud with row-level lineage.
Every part / model combination gets its own baseline. Statistical models (in HANA PAL) flag departures from expected long-run failure rates — separating short-term dynamics, seasonality, and causal covariates.
Claim-line features (repair-shop location, claim frequency, part combination) fed to an ML classifier that scores each claim on defect probability vs abuse probability.
Emerging patterns surface in SAC weeks before they trip a manual threshold. Engineering opens a case, engages the supplier, isolates the batch — all before public awareness.

The value
Directional ranges based on comparable SAP BTP deployments in this pattern. Your baseline will define your actual delta.
Weeks
earlier defect detection
Emerging pattern surfaces before it becomes a recall event.
5-15%
reduction in warranty reserves
