A quality assessment performed before mass production begins to validate materials, tooling, and process readiness.
Pre-Production Inspections give buyers confidence that the supplier interpreted specifications correctly before committing to a full run.
PPIs verify that the control plan is understood by the production team.
What PPIs cover
Inspectors review raw materials, first assembled units, and production fixtures to confirm alignment with drawings.
They also evaluate operator training, SOP availability, and environmental conditions that could impact quality.
Benefits for buyers and suppliers
Early feedback reduces the cost of change and avoids rework later in the production cycle.
A thorough PPI often streamlines the subsequent FAI by resolving open questions.
Key takeaways
- PPIs validate supplier readiness before mass production.
- They reduce the risk of expensive late-stage corrections.
