Defect rate

Definition

The defect rate is a measure of the number of defective items produced in a manufacturing process, expressed as a percentage of the total items produced. It helps organizations understand the quality of their products and plays a crucial role in evaluating performance and driving continuous improvement efforts. A lower defect rate indicates higher quality and efficiency, while a higher rate signals the need for process evaluation and enhancement.
