Choosing the correct AQL level involves understanding the balance between quality control and cost. AQL (Acceptable Quality Level) is a standard for deciding the maximum number of defective items acceptable in a sample. Determine the level based on the criticality of defects: critical, major, or minor. For high-risk products, opt for a lower AQL (e.g., 0.1-0.4%). For lower-risk items, a higher AQL (e.g., 2.5-4.0%) may be sufficient. Consult industry standards and specific client requirements to guide your decision.
