This document summarizes a quality control circle (QCC) workshop from November 7 to December 7, 2011 that aimed to reduce wrinkle defects in a classic leather shoe model produced in Area 2B. The team of 8 members from different departments developed a project plan and tracked their progress. Their goal was to reduce the defect rate of 6.1% to the target of 3% or lower, which could save the company an estimated $1,518 per order through reduced costs from lowering prices on defective shoes. They applied the CEDAC problem-solving method and created a Gantt chart to manage their activities.
