Paragraph starter

The application of Lean Six Sigma (LSS) methodology in manufacturing environments has demonstrated significant potential for waste reduction and process optimization. As evidenced by Hassan (2019), implementing LSS in a welding wire plant led to a notable decrease in waste and an increase in production yield, supported by a structured analysis of waste causes and the use of tools like the Analytic Hierarchy Process (AHP) for prioritization. This approach offers a robust framework for designers and engineers to enhance the efficiency and sustainability of production processes.
