Title: REDUCING SCRAP WITH LEAN SIX SIGMA: A COMPREHENSIVE APPROACH.

Abstract: The purpose of this study is to provide empirical evidence of the benefits of implementing Lean Six Sigma (LSM), in a factory setting, for reducing non-conforming costs and improving production efficiency. This paper explores the application of LSM in scrap reduction, underscoring key stages and protocols of the implementation. By applying LSM methodology, the project selected as a case study focused on identifying and eliminating the causes of scraps and minimizing variability in manufacturing and business processes. The resulting improvements led to a significant reduction in rework, positively impacting the costs associated with raw materials. It also resulted in improved production efficiency and a decrease in customer complaints. Theapplication of the study is limited to a single factory case, belonging to a multinational company from the energetic industry in North-western Romania, and the results may not be generalizable to other settings. Further research is needed to explore the long-term effects of the LSM implementation. The successful implementation of LSM in the study demonstrates its potential for improving production efficiency and reducing costs in a manufacturing setting. It provides empiricalexample for other factories considering similar initiatives. This study contributes to the expansion of the existing literature, by closing gaps between LSM conceptual elements and empirical research, by presenting the results of a project regarding the implementation of LSM methodology within a production process.
