Abstract

This study explores the application of proportion defective charts as a tool for enhancing quality control in apparel production. Proportion defective charts, a type of control chart used in statistical quality control, monitor the proportion of defective items within production batches to ensure that manufacturing processes remain within acceptable quality limits. By implementing these charts, the study aims to identify variations and trends in defect rates, providing actionable insights for improving quality control measures.

The research involves analyzing data from multiple apparel production lines, focusing on defect rates recorded over a specified period. Through the use of proportion defective charts, patterns of defects are tracked, and the effectiveness of current quality control practices is assessed. The study also examines how these charts can be utilized to detect process deviations early, enabling timely interventions and reducing the overall incidence of defects.
