AQL Sampling

Statistical Inspection Plans

100% inspection is often impractical or impossible. I design Acceptable Quality Limit (AQL) sampling plans based on industry standards like ANSI/ASQ Z1.4. This allows for statistically valid decisions on lot acceptance without the cost of inspecting every unit.

I tailor sampling plans to the specific risk profile of the product and the supplier's history, ensuring an optimal balance between inspection costs and quality assurance.

Key Competencies

• ANSI/ASQ Z1.4 Standard Application
• Defining Inspection Levels and AQLs
• Switching Rules (Normal, Tightened, Reduced)
• Operating Characteristic (OC) Curves
• Risk Assessment (Producer's vs. Consumer's Risk)
