THE ANALYSIS OF METHODS FOR EVALUATION AND MONITORING THE PROCESS OF INDUSTRIAL QUALITY CONTROL
The article describes seven Japanese tools for managing the quality of production process, their relative strengths and weaknesses. The evaluation criteria used were as follows: the area of method application; the method of data comparison; the objectives pursued; the type of data collection; the sample size; the methods of data analysis and presentation; the form of analysis implementation; variability and features of diagram plotting; the method of efficiency evaluation; the method of verifying the correctness of method implementation. Based on the results of the study, the combined method has been developed which consists of consecutive processes, namely, Ishikawa diagrams, scatterplots and Pareto charts. The findings obtained in the article will facilitate the choice of the appropriate method for specific production conditions. The proposed combined method can become a successful alternative to application of Japanese tools of quality management and control
