Analysis on the usage of techniques and tools from the Six-Sigma program on a survey-type assessment

Abstract

The Six-Sigma program is an approach currently adopted by many companies and its usage occurs through a highly disciplined and guided process, in which several techniques and tools are applied, trying to generate a continuous improvement cycle. Facing this fact and considering the relevance of the subject, a survey-based research was carried out. One of the objectives was to identify and analyse the techniques and tools used in the phases of the DMAIC and their comparison with the literature. The results consisted in assessing the techniques and tools most and least used by the companies, enabling to confront those with other previous research. It is also worthy highlighting that these results confirmed the indications of other publications, which state that the Six Sigma programme needs to be supported by measurable and trustworthy data. This makes evident that the usage of techniques and tools is indispensable for the DMAIC improvement method.
