<![CDATA[In the two-wheeled automotive manufacturing industry, product quality has a significant influence on customer confidence as well as production efficiency. Therefore, this research was carried out to apply the Seven Tools method to provide effective solutions in quality control, so that the production process can run smoothly and meet the set quality standards. This study aims to analyze the quality control of KWBF arm rear brake products using the Seven Tools method. The three types of defects found are scratch material, rust, and blank minus. The main causes of such defects include human, machine, method, material, and environmental factors. As an improvement effort, the researcher suggests regular training for machine operators, regular machine maintenance, selection of raw materials before production, and monitoring of environmental conditions during the production process. The application of the Seven Tools method has been proven to help companies systematically detect defects and provide more targeted repair solutions to improve product quality.
