# Audi Neckarsulm: WPS Analytics full-population inspection

Quality can move from ultrasound sampling to AI screening of every weld.

Function: Engineering design. Patterns: Threshold as the human control; Exception-based operations. Evidence: reported.

Freshness: current. Reviewed: 2026-08-23. Updated: 2026-08-22.


Source quality: 1 independent, 1 primary; publication outcomes are reported.

## Before

1. **Audi quality technician** — Uses ultrasound to inspect a random sample of resistance spot welds. (control: About 5,000 weld checks per vehicle reported; sample-based control remains in parallel.)
2. **Quality engineer** — Reviews sampled findings and directs investigation or rework. (control: Audi quality procedures and human disposition.)

## After

1. **WPS Analytics** — Analyzes process data for approximately 1.5 million welds across 300 vehicles each shift. (control: Machine-learning screening covers the population; traceability designed with quality/Fraunhofer bodies.)
2. **Quality technician and engineer** — Focus on flagged anomalies and continue random ultrasound validation. (control: Humans own disposition; full coverage is not proof of zero defects.)

## Decision rights

Audi sets thresholds; humans disposition anomalies.

## Exception path

Flagged or uncertain welds receive manual ultrasound review.

## Outcomes

- **Inspection coverage** (reported): Random checks around 5,000 welds per vehicle → AI analyzes about 1.5 million welds on 300 vehicles each shift. Operator coverage, not defect escape-rate evidence.

## Executive lesson

Skilled inspection shifts from broad sampling to anomaly disposition.

## Anti-pattern

Do not infer zero defects from 100% coverage.

## Questions for leaders

- Where is the operating threshold set and who can override it?
- What measured result would trigger rollback or retraining?
- Which residual decisions must remain human-owned?
