What is a During Production Inspection (DPI)?
A During Production Inspection (DPI), also called a During Production Check (DUPRO), checks your products early in the production process to make sure they conform to your standards. Inspecting after production is finished is often too late - by catching issues early, defects can be addressed and reworked without delay, and the same problems avoided for the rest of production.
- Performed when 30-50% of finished goods are produced
- Catches quality issues before it is too late
- Identifies defects for early corrective action (CAPA)
- Verifies production schedule for on-time shipment
