Abstract: Abstract National and international markets are seeing the impact of globalization, and all aspects of operations are looking for excellence in the global competitive economy. Six sigma can be an effective solution for achieving good performance in developing small and medium-sized companies, among many high-quality control methods. The DMAIC model has been used in current studies to decrease the process differences of the bead splice triggering material wastage. This six-sigma DMAIC study is being conducted by the customer’s voice in the specified phase by problem identification. The key problem consists of collecting current tire bead specification details. The control charts of the procedure were used for detailed monitoring and process management. The standard deviation was lowered from 2.17 to 1.69, using DMAIC methods. The process capability index (Cp) value was increased from 1.65 to 2.95 and the process capability index (Cpk) value was increased from 0.94 to 2.66, respectively. A DMAIC methodology has been developed that can play a key role in reducing defects in India’s tire fabrication process.
