SIX SIGMA APLICADO A EMPRESAS MANUFACTURERAS PARA MEJORA DE PROCESOS DE PRODUCCIÓN

Abstract

Since Motorola developed Six Sigma in 1986, it has popularized and spread out to the whole world. At the beginning, this methodology was only applied on manufacturing processes, but today it’s used on any area of any type of business. Six Sigma allows reducing processes variations to the minimum throughout its process improvement methodology called DMAIC and the support of a wide variety of statistical tools. Its benefits are clearly seen in the success that many companies have had when applying it. Nevertheless, its implementation is tough and many companies have failed implementing it. This research paper presents a literature review of the core concepts of Six Sigma and the critical success factors for its successful implementation in manufacturing companies. Moreover, a five-case analysis is made on successful implementation of Six Sigma projects, through which, the author pretends to suggest an efficient way to implement the methodology in manufacturing companies to improve production processes.
