Product quality management refers to a set of activities, which allow checking the product quality and eliminating any inconsistencies. In eliminating incompatibilities its necessary to identify their root causes. It is possible by using the selected quality management techniques. As it was shown, it is very useful after analyses the incompatibilities identified by popular non-destructive tests (NDT), which are used to check an incompatible product. It was concluded that practice quality management techniques after NDT are necessary because NDTs are effective in finding incompatibilities in the product (without its destruction) but not identifying their causes. The aim of the study was the analysis of using the selected quality management techniques (Ishikawa diagram and 5Why method) to identify the source of the porosity which was detected by the fluorescent method. The problem was identified in an enterprise localized in the Podkarpacie region. But after identifying the incompatibility in the product, no further analyses to find the root cause of the problem occurrence were made. After the NDT (fluorescent inspection method) on the product (made from 410 steel) used in the aviation industry, the porosity was identified. Because the root cause of porosity was not known, the sequence of the Ishikawa diagram and 5Why method was used. These methods were used in an adequate way (first the Ishikawa diagram and second the 5Why method) because only in this way it is possible to find the root cause of the problem. By the Ishikawa diagram, the potential causes and two main causes (i.e. inadequate preparation, water in molding sand) were identified. The source of the porosity (contaminated material) was found through the 5Why method. It was concluded that the selected quality management techniques (Ishikawa diagram and 5Why method) were useful in finding the root cause of the porosity of the product. Additionally, the paper proposed the use of the Ishikawa diagram and 5Why method after the NDT test, and this sequence was effective in finding the root causes identified by NDT tests, so it can also be used to solve other problems with incompatibilities.
