Research on B Product Quality Improvement Based on DMAIC
This study applies the Six Sigma DMAIC method to enhance the quality of Product B by addressing its defects. The Define phase outlines the production process and key issues, using a Pareto chart to prioritize the main defects. The Measure phase verifies data accuracy and collects relevant quality data. The Analyze phase employs an NP control chart to assess system stability and identify root causes. The Improve phase implements targeted solutions, while the Control phase ensures sustained results. Post-improvement, defect rates significantly decreased.The results demonstrate Six Sigma DMAIC’s effectiveness in quality improvement, offering a practical case for SMEs to optimize product quality.
