Purpose The purpose of present study is to expose the detailed review for benefits and challenges about implementation of Lean Six Sigma (LSS) in business organization and spread of LSS literature in term of various sectors wise, research methodology wise and journal wise. Design/methodology/approach This paper covers the literature on LSS from 2000 to 2018. The authors have selected a large number of research papers using the keywords as Lean Six Sigma implementation in automotive, micro small medium enterprises, health care, education, financial sectors and many more. A total of 216 research papers have been reviewed on LSS distribution of sector wise, research methodology adopted, active countries, year of publication and critical barriers in implementation of LSS. Findings The present literature classifies the spread of LSS in four important sectors of manufacturing, health care, human resource, financial and education. It presents the critical barriers and benefits of LSS implementation in various sectors mentioned above and an important research gap, where practitioner/researcher can focus more during their research on LSS. Practical implications It is important for industry, researchers and LSS practitioners to be aware about challenges and success factor during LSS implementation in various sectors such as manufacturing, education, financial, human resource and health care. Hence, this paper could provide significant and valuable insights to industry and practitioners for successful implementation of LSS projects. Social implications LSS results in reduced waste, defects and improve process, which in turn provide high-quality products at minimum cost, and this leads to customer delight, which ultimately raises the societal living standard. The results encourage LSS practices without fear because there is a huge discussion of near about all success and failure parameters about LSS. Originality/value To the authors’ best knowledge, no studies have still covered the literature review of LSS implementation in three different sectors: manufacturing, service and process. The present study was mainly focused on presenting a systematic review of literature in said sectors and found the gap between current status and future direction for the implementation of LSS in different areas.
