The study the possibility of using selected tools/methods of the Lean Manufacturing concept and tools supporting quality management in reducing production problems, was presented. The own research was divided into three stages in which production problems were identified, methods of reducing them were identified, and their effectiveness in terms of problem elimination/reduction was assessed. It was possible to identify the causes of the problems thanks to the 5Why method and the cause and effect diagram (Ishikawa diagram). In terms of the methods/tools of the Lean Manufacturing concept, the following were used: 5S method, visual management, One Point Lesson (OPL), Kaizen, Total Productive Maintenance (TPM). Own research was carried out in the automotive industry. The identified production problems include: stoppage of the production line, incorrect bending process, waste. Each of the methods/tools used had a different effect on limiting the identified production problems. For the purposes of the study, a three-point scale was also adopted, allowing to determine the impact of tools/methods on reducing the identified problems. Therefore, it turned out to be important to implement several methods/tools simultaneously. The implemented methods allowed for the effective limitation of the occurrence of the identified problems.

The paper presents the results of qualitative analysis and improvement of the printing process with UV inks on glass packaging with the use of selected quality management tools and methods. The research was carried out in a glass factory located in the Silesian Voivodeship in Poland. The qualitative analysis included the risk assessment related to the printing process with UV inks, print quality, and the type of nonconformities occurring during printing. Based on the conducted analyses, proposals for improving the printing process with UV inks were determined. As part of the analyses, such methods and quality tools as fault tree, FMEA analysis, Pareto-Lorenz diagram, and tree diagram were used. It was found that the most common nonconformity of printing with UV inks on glass packaging is smearing of the emulsion covering the glass vessel and that most of the nonconformities resulted from errors made by employees, which were caused by non-compliance with the instructions for individual activities by people employed in production positions and quality inspection employees. It was proposed to implement employee training at individual workplaces, in particular the implementation of instructions for performing specific activities, as well as the introduction of additional employee supervision and implementation of changes in the management of the printing process and quality inspection of the decorated products.

The article concerns the use of selected quality tools to analyze and evaluate the quality of homogenized cheese produced by the examined District Dairy Cooperative. Quality tools such as a histogram, Ishikawa diagram, interrelationship diagram, and tree diagram were used to analyze and evaluate numerical data and quality problems and search for solutions. The stability of the net mass of the tested product was assessed, for the purpose control cards were used, and the qualitative capability of the process was assessed with the use of Cp and Cpk indices. It has been shown that the dosing process is statistically stabilized, but this process cannot be considered qualitatively capable. It has also been shown that the quality of the product is influenced by various factors that are related to the occurrence of non-conformance and are related to each other. It was determined that in order to improve the production process and improve the quality of the food product, it is necessary to provide training for employees, to improve their working conditions and to motivate them accordingly. The frequency of inspections of the production line should also be increased, as well as the best adjustment of the settings of machines used in production.

The basic objective of this paper is to present the possibilities of applying selected quality tools in analysing the reasons for discrepancies as exemplified by the process of manufacturing wet refractory mortars. Using various methods and tools, the authors looked for the root causes of a quality rejects occurrence. The following selected methods and tools were used: analysis of variance – ANOVA, the individual moving range (I-MR) chart, SIPOC process mapping, analysis of regression, identification of potential root causes of a problem – 7M, Gauge Repeatability and Reproducibility (GRR). The paper shows how it is possible to search for the causes of quality rejects by means of deliberately selected tools and methods and to successfully decrease the number of discrepancies after introduction of the appropriate corrective actions. The authors indicate how it is possible to analyse the processes of manufacturing wet refractory mortars and what can be done in the situation when a faulty measuring system (returning seriously erroneous results) is the reason for a lack of or lower detectability of wet mortar flaws as it has affected the accuracy of feeding of all components of the recipe, as well as the consistency, moisture content, and hardness/softness of mortar. The collected analysis results allowed the authors to conclude that there were seven probable root causes influencing the hardening of mortar and the loss of its primary functions. This paper could be useful for those wet refractory mortars manufacturers who find it difficult to build their knowledge about product properties based on available publications sources.

Process of control and meeting standards over the whole manufacturing process allow for providing customers with products or services with expected quality, which largely determines the competitive advantage of the enterprise. Consumers more and more often emphasize the quality of goods manufactured and the criterion of the price is often not the dominant criterion when choosing a product. This situation is observed in the automotive sector, where safety of using vehicles and human health and life are in the first place. Therefore, on the one hand, it is essential to eliminate the quality defects, and, on the other hand, one should familiarize with the causes of these defects and to prevent from them in the future. This is possible and necessary in the automotive sector, which uses the international standard of ISO/TS 16949 by employing tools and methods of quality management. This study uses the Pareto chart and the Ishikawa diagram in order to identify significant inconsistencies and the related costs in the process of manufacturing of single-conductor automotive cables, special cables (NON-PVC) and battery cables.
