Resumen
Six Sigma (SS) has evolved from a tool to eliminate defects in production, to being a strategic improvement
methodology. The literature repeatedly indicates that a significant number of companies have not achieved their objectives and
obtained the expected benefits from their SS projects; although the theory explains part of the problem of SS project
management and the effectiveness of Work Teams (WT), it does not provide definitive answers for companies to achieve
success, nor does it explain reasonable and objectively the factors that influence the effectiveness of the WT of SS projects. In
this sense, it is important to identify the main factors influencing the implementation of SS in the manufacturing industry, as
well as develop the theory explaining the achievement of manufacturing objectives by SS in industrial plants located in Ciudad
Juárez, Chihuahua, Mexico.
