Manufacturing Defect Improvement Initiative
Recently, a dedicated improvement team has been established to address long-standing production issues—primarily focusing on products with high defect rates. The team comprises members from departments such as technology, manufacturing, and quality inspection. They hold daily meetings to discuss these challenges, propose targeted improvement measures, assign clear responsibilities, and systematically track and verify the effectiveness of both the improvements and their implementation. The goal is to reduce the defect rate of these persistently problematic products back within the specified acceptable range—and to ensure that continuous improvement efforts can be sustained over time.
