First Pass Yield (FPY)

Definition

First Pass Yield is a manufacturing quality metric measuring the percentage of batches or units that complete the production process correctly on the first attempt, without requiring rework, scrap, or triggering a deviation. It's a commonly tracked KPI for evaluating overall process capability and consistency.

Benefits

Tracking FPY through EBR data over time helps manufacturing and quality teams identify whether process changes, equipment upgrades, or training initiatives are actually improving right-first-time performance, rather than relying on anecdotal impressions.

Use Case

A manufacturing site notices FPY has declined over several months after reviewing EBR-derived trend data. Investigation ties the decline to a specific equipment line, prompting a targeted maintenance review rather than a broader, less-focused process investigation.
