PT Cahaya Perada Abadi is a manufacturing company that manufactures leather and fabric based products, with golf gloves as their main product. Nevertheless, PT CPA is struggling to keep the quality of their product, because the defect percentage of golf gloves is still high. Data shows that the manufacturing process in PT CPA still produces 26,25% of defect during 2 months period. PT CPA’s acceptable defect percentage is less than 5%, which is far lower than the current performance. Therefore this research aims to improve the production process using Six Sigma methodology, utilizing the DMAIC approach (Define, Measure, Analyze, Improve, Control) to help PT CPA in enchancing product quality and reducing defect rate. The Six Sigma project starts with the define phase to elaborate the issue and formulate the Six Sigma project at PT CPA. Progressing to the measure phase, it is shown that the production process capability stands at a DPMO value of 64.910 and sigma level of 1,85. Moving to the analyze phase, Delphi method is used to identify the root causes of the 5 defect categories. The result of the analyze phase is used as the foundation to generate the alternative solutions in the improve phase, resulting in six alternative proposals. Among these, 2 solutions are accepted for implementation. The first is the formulation of SOP for cutting pattern process with camera monitoring and SOP for segregating defect products with camera monitoring. Lastly, control phase is yet to be fully executed and still remains speculative in nature. However, based on estimation, it is shown that there is a noticeable reduction in Risk Priority Number (RPN) compared to its initial value, specifically reducing from 453 to 210 or 53,6% lower than its initial value. The result implies that the process improvements are anticipated to effectively reduce defect rates and improve the production process capability at PT CPA.
