Lean Six Sigma (LSS) is a continuous improvement approach that aims to improve process efficiency and effectiveness. This study explores the latest developments, current trends and perspectives of LSS in the manufacturing sector. LSS critical success factors (CSFs) in manufacturing are also discussed. The results of this study revealed the most important contributions in terms of publications, authors, countries, application, objectives and tools of LSS. The results found that applying the LSS approach can improve quality, reduce process variation, eliminate waste, improve production rate, improve process productivity, reduce cycle time, reduce non-value-added time, reduce lead time, reduce production cost, and reduce unit price, and increase customer satisfaction. Furthermore, the results can be used for a systematic literature review by researchers and manufacturing leaders before embarking on a continuous improvement journey. Finally, a LSS-DMAIC framework is developed to improve manufacturing efficiency and effectiveness.
