Manufacturing & Supply Chain Governance

A vision system has inspected batch #QG-7741 of semiconductor wafers. Dimensional tolerance check: 94.2% within spec (threshold: 95%). Surface defect scan: 0.3% defect rate (threshold: 0.25%). The batch is borderline. Rejecting costs £47,000 and delays shipment by 6 days. Passing risks downstream yield loss and potential customer claim. Should the system pass or reject this batch?

Stakes — Irreversible — once passed to next process, rework cost increases 10x

Key constraint — Must not pass batch if any single parameter exceeds threshold
