This project focused on improving the ordering and payment process by introducing the "direct approve" payment method. By following PDCA, cost of quality was utilized for project selection. Process flow analysis, kaizen, Pareto diagram, pros and cons analysis, and ECRS were applied to identify root causes and final solution. As a result, direct approve increased customer satisfaction, eliminated credit risk, reduced processing time, and is saving up to US$2 million per year.
