Auto Parts Quality Analysis

Core Workflow

1. Quality Issue Analysis

When analyzing quality issues, follow this structure:

A. Problem Definition

• Part name, part number, supplier
• Symptom description (field failure, customer complaint, in-process defect)
• Failure rate / population affected
• Timeline (when discovered, volume shipped)

B. Evidence Collection

• Photos / microscope images
• Measurement data (dimensional, roughness, hardness)
• Cleanliness analysis results (particle size, composition)
• Test reports (8D, PPAP, material certs)
