System of dependencies for quantitative assessment of Enterprise Quality Management Systems

Abstract

The ISO 9000 standards require the methods for quantitative assessment of quality management systems (QMS) processes. A systemic approach to the QMS analysis allowed identifying their features. Taking them into account the method of process quality assessment has been worked out. This paper proposes using one of the limiting distributions of extreme statistics for assessment of the QMS processes quality. Using the symmetry principle with the limiting distribution of the smallest sample, the limiting distribution of the largest sample was obtained, as well as a number of additional intermediate functions. Thus, the system of dependencies of heterogeneous indicators of processes quality with a dimensionless scale was developed, taking into account the significance of the QMS processes. The proposed system of dependencies can be used at any enterprise for quantitative assessment of the QMS processes quality, that will allow taking into account the process significance and position in the system, as well as the diversity of its quality indicators.
