Attribute inspection measures __________.

Attribute inspection specifically focuses on determining the quality of a product by classifying it as either acceptable or defective based on predetermined criteria. Rather than measuring the degree of defects or variations in a product (which is often considered in variable inspection), attribute inspection provides a straightforward yes/no assessment. This binary classification allows quality control personnel to quickly identify defects, ensuring that only products that meet quality standards are accepted for distribution or sale. This method is particularly useful in scenarios where products can be easily categorized without needing to analyze specific measurements or quantities.

While the other concepts—cost-effectiveness, equipment efficiency, and worker productivity—are important aspects of operations and supply chain management, they do not directly relate to the primary function of attribute inspection, which is solely about identifying the quality status of products.
