The study explores the application of lean six sigma in case study of finding recommendation to solve real time production problems to increase efficiency and utilization while looking into manufacturing wastes which have a direct implication on production output. The study considered real production problem and the information was gathered was based on the station workload (time study and process waste) looking an efficiency and utilization of production line. The optimization of production process was based on work-study principles like lean six sigma, kaizen, time study. Data collection used is survey & direct observation in a form of a time study. Based on LSS application, it was discovered that the current production performance standard can be improved & utilization can be increased and more manufacturing wastes were generated. The outcomes show that in this balancing situation, the suggested framework performs better than earlier approaches. The findings would offer insightful recommendations for balancing the line and increasing utilization to enhance assembly lines.
