Sažetak
It is almost two decades since the creation and the wide world implementation of the Six Sigma methodology, and there are still intensive discussions about its statistical definition. The Six Sigma statistical definition can be summarised in the following way: Six Sigma represents the reduction of variations (dispersion) of the process to the level at which a maximum of 3.4 non-conformities to a million opportunities (DPMO) can occur, on a long-term basis (1.5σ shift). The interpretation of the 1.5σ shift introduces an entire series of dilemmas regarding the correct usage of the Six Sigma metrics. The dilemmas are intensified also by the authors of publications from this area regarding the differences in the approaches and the terminology, and especially related to the interpretation of the process capability index. This paper will attempt to explain the Six Sigma statistical definition. However, the explanation may cause also additional confusion.
