The successful management of product incompatibility remains a challenge. Therefore, the study aims to analyze the possibilities of effective management through qualitative analyses. The sequence of two quality management techniques added to the fluorescent method was proposed. These techniques were the Ishikawa diagram and the 5Why method. For a specific incompatibility example identified by using the penetration tests (the fluorescent method), the causes of these incompatibilities were searched using the Ishikawa diagram and the 5Why method. An analysis example was the linear indication problem on the product surface, the gasodynamic sealer. By supplementing the penetration method, the proposed sequence of selected quality management techniques has shown that it is possible to detect incompatibilities and identify the source cause, also. In turn, finding the source cause can allow proposing the improvement actions. The proposed solution can also be used in other quality problems and other enterprises to improve the production processes.
