This paper discusses OEE index used for identification of critical locations in the technological processes of manufacturing casting products. Analysis involved nine stages in technological process, starting from casting through cutting to washing and drying. Then, we analysed how product quality varies at the stages of technological process in order to verify whether it depends on the presence of bottlenecks. For this purpose we used r correlation coefficient.
