Factores Críticos del Éxito de Proyectos Seis Sigma y de Manufactura Esbelta

Abstract

Literature is extensive regarding the increases of efficiency by Six Sigma and Lean Manufacturing 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, literature is inconclusive. A literature review of 52 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 95 indicators, which is validated with KMO and Bartlett’s tests. The questionnaire is applied to a sample of 225 engineers with experience in Six Sigma and Lean Manufacturing projects working in high tech manufacturing companies, to identify the factors used in the industrial practice and their contributions to success. 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 structural model and its components are presented in this paper.
