Abstract

This research paper presented the applications of Lean Six Sigma (LSS) in production systems. This narrative research is based on the review of previous studies. Literature review is summarized, discussed and presented in tables. Since, the quality improvement & defects reduction have been the severe problem in industries due to its association with cost; thus it has been the focus of academicians and practitioners to study and implement such quality improvement & defects reduction philosophy. Since, lean manufacturing is an effective waste elimination technique and its tools have captured the immense attention of academicians and practitioners for quality improvement & defects reduction. Therefore, there is an extreme need to conduct such studies about the usefulness and drawbacks of the implementation of lean tools. In future, other lean tools can be discussed in depth to put clearer and broader picture and to draw more comprehensive conclusion. Moreover, existing studies lack to investigate the implementation in various sectors. Studies related to LSS are significantly important in development of lean knowledge due to individual sectors have major differences in their processes. In this regard, present review is conducted so as to put the open and broader picture of Lean Six Sigma (LSS) comprehensively.
