BRIBIESCAS SILVA, Francisco et al. Critical Success Factors of Six Sigma and Lean Manufacturing Projects. RIDE. Rev. Iberoam. Investig. Desarro. Educ [online]. 2023, vol.13, n.26, e053.  Epub 09-Out-2023. ISSN 2007-7467.  https://doi.org/10.23913/ride.v13i26.1497.

Literature is extensive regarding the increases of efficiency by Six Sigma and Lean Manufacturing (SS/LM) projects, including reports of questionable results and the lack of reasonable explanations about those cases. In the search of the factors influencing the success of the projects, the literature is inconclusive. Therefore, the objective of this work is to determine the factors influencing the success of those projects. For which, a literature review was carried out finding that 48 publications gave a list of 29 factors, which is reduced to 21 by a Meta-Analysis study. These factors are used for the development of a questionnaire with 4 constructs and 25 indicators, which is validated with KMO and Bartlett’s tests. To identify the factors used in the industrial practice and their contributions to success, the questionnaire was applied to a sample of 225 engineers with experience in Six Sigma and Lean Manufacturing projects working in high tech manufacturing companies. The specification of the structural model starts with an exploratory factorial analysis-oblique rotation and the method of Principal Axes with Promax rotation, afterward for the empirical evaluation several indexes were used. The critical success factors and the usefulness of SEM for these purposes were determined. The structural model and its components are presented in this paper.
