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.
