Unraveling the key determinants of successful six sigma implementation: an empirical investigation

AbstractThis article aims to analyze the importance of critical success factors in effectively implementing Six Sigma. It delves into the determination of key factors and attributes that contribute to successful adoption, considering that not all Six Sigma endeavors have achieved the desired outcomes. According to the research, a significant portion of corporate Six Sigma initiatives (approximately 60%) fail due to incorrect integration of vital factors and misguided assumptions. To conduct the study, a research survey incorporating a Likert scale questionnaire with a simple random sampling method was distributed among 2,325 potential participants, resulting in 573 responses, primarily from Germany, the United Kingdom, and Sweden. Through various structural equation modeling (SEM) approaches, such as exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), the study revealed four essential elements for success: (1) the competency of belt system employees; (2) project management skills; (3) organizational economic capability; and (4) leadership commitment and involvement. These findings hold significant implications for institutions, practitioners, and researchers seeking to incorporate these elements into their Six Sigma deployment strategies for long-term success. The study's originality lies in its contribution to assessing critical success factors in Six Sigma deployment within the European automobile industry, utilizing a mixed-methods research design supplemented by descriptive statistics.Keywords: Six SigmaCritical Success FactorsSurveyEFACFAautomotive industry Disclosure statementNo potential conflict of interest was reported by the author(s).
