QUALIMETRIC METHOD OF EVALUATION OF PROCESSES OF THE QUALITY MANAGEMENT SYSTEM OF ENTERPRISE

The article studies the problems of ensuring product quality at enterprises and implementation of quality management systems in accordance with the ISO 9000 series standards. It is noted that the standards contain requirements for assessing the effectiveness of quality management systems, but do not provide specific methods for measurement, which complicates the process of objective quality assessment. To solve the problem of quantifying the effectiveness of the quality management system, the author proposes to use qualimetry methods, which allow converting single quality indicators into a dimensionless scale. A detailed analysis of existing approaches to assessing product quality is carried out, and it is concluded that such approaches are not effective enough to assess management systems, since they do not take into account the heterogeneity of quality indicators of processes and systems. The article classifies the QMS processes into three main groups: mandatory processes (according to the standard), supporting processes, and product life cycle processes. For each of these groups, the key performance and efficiency indicators are allocated, which allow assessing the quality of management of individual processes. It is also proposed to use Harrington's desirability function as a tool for integrating individual quality indicators into one generalised indicator. A method for evaluating the processes of the quality management system has been developed, based on the identification of key performance and efficiency indicators for each process. It is proposed to use the geometric mean of these indicators to obtain an overall assessment of process quality.
