This research aims to apply Lean techniques to reduce waste in the production process of a pottery company to below 10%, enabling the company to meet increasing customer demands and shorten production times. Through a case study, Lean tools were utilized to improve process planning and control, employing the Deming Cycle for continuous enhancement. The research was conducted in five phases, beginning with data collection that revealed a 23% waste rate in the firing process over four months. Subsequent analysis identified key issues using Pareto diagrams and Fishbone Diagrams. Implementing targeted improvements, including temperature control in the firing process, reduced waste by 10-15%, ultimately lowering the overall waste rate to below 10%. This demonstrates the effectiveness of Lean techniques in optimizing production efficiency and reducing waste in the pottery industry.
