Baseline Acceptable Quality Limit Qualification Matrix Setup
A clear AQL matrix binds defect classification to statistical sampling tables, shifting commercial re-inspection costs to factories on lot failures.
Defect Categorization
Meaning
Information architecture within a quality report provides a structure for sorting production errors. Through defect categorization, a manager can distinguish between failures that stop production and those that require only cosmetic correction. This structure enables a systematic evaluation of a batch against the agreed acceptable quality levels.
It provides a framework for the decision to accept or reject a shipment.
Sorting Logic
Assigning a severity level to each found error ensures that resources are directed toward the most prominent issues. The process of defect categorization relies on a predefined list of possible failures and their assigned ranks. A scratched surface is treated differently than a broken internal component.
This logic helps the factory understand which parts of the manufacturing process require the most improvement.
Classification Process
Inspectors use a reference document known as a defect classification list during the physical examination of the goods. While performing the check, the worker records every instance of a deviation from the golden sample. Through defect categorization, the total number of errors is tallied within each specific tier.
This tally determines if the batch falls within the statistical limits defined by the sampling plan.
Quality Assessment
Final reports summarize the health of a production run by presenting the results of the sorted data. Effective defect categorization allows a buyer to see if a supplier is struggling with cosmetic issues or functional failures. A batch with many minor errors might still be sellable, whereas one with a few major errors might be rejected.
