Abstract
This chapter studies Critical Success Tools and Techniques (T&Ts) of Six Sigma (SS) strategy reported by researchers and practitioners. The main objectives of this research are to describe the current situation of SS and collaborate in the understanding of its successful implementation. This study was carried out through an extended literature review. Moreover, two periods of time were analyzed in order to emphasize on the evolution of SS. Such analysis relied on odds-ratio and hypothesis testing for proportions to study the most important T&Ts reported in almost two hundred of successful works related to SS projects. Afterwards, such T&Ts were identified and described. From this perspective, this chapter can be a useful guideline for training in companies, since it highlights the T&Ts most frequently used in successful projects, which have managed to improve the processes, reduce costs, and increase customer satisfaction in companies.
