“…Using statistical and reliable data and analysis tools and techniques within systematic roadmaps, LSS implementation in manufacturing facilitates breakthrough results with enhanced quality of products and services (Gijo et al, 2018;Zhang et al, 2016;Thomas et al, 2016;Sharma Green implementation of Lean Six Sigma and Sharma, 2014). Adina-Petruta and Roxana (2014) presented key strategic benefits of LSS as sustainable improvement with high productivity level and accelerated results, while many scholars have presented operational benefits of LSS as reduced process variability, improved product quality, waste and defect reduction (Singh and Rathi, 2019;Thomas et al, 2016;Tlapa et al, 2016;Chaneski, 2016;Dragulanescu and Popescu, 2015). Despite extensive evidence for benefits of LSS, many scholars have identified key barriers for its implementation in the manufacturing sector such as resistance to change, expenses, lack of resources, poor project selection, the wrong perception of LSS as a set of tools and techniques, inefficient use of techniques and resources, misalignment between project goals and manufacturing strategy, ineffective project management and poor communication (Singh and Rathi, 2019;Yadav et al, 2018;Albliwi et al, 2014;Ismail et al, 2014).…”
