Purpose: The main goal of the research was to determine the spectrum of instruments supporting management processes that are used to improve the quality of products in terms of sustainable development. We analyzed the degree of their use in the practical functioning of the surveyed enterprises. In addition, the aim of the research was to determine the scope of application of the indicated instruments or the possibility of their use in the decision-making process relating to the improvement of the broadly understood quality of products. Design/methodology/approach: The research method applied are: 1) standardized survey research making based on a survey conducted in contact and remote way conducted in 78 enterprises in south-eastern Poland; 2) analysis of the source documentation and in-depth interviews. It is a component of broader research. Findings: The following methods were used in decision-making processes with varying frequency: the Delphi method by 58% of respondents, Tree of Failure Analysis (by 52%), Event Tree Analysis (by 44%), and the QFD method (by 41% respondents). The surveyed companies that have implemented a vapour management system based on ISO standards tend to use 5 methods out of 25 cited in this study (these are a survey, brainstorming, 5Why and/or 5W2H, benchmarking, and the Delphi method). As a result of using mainly the above mentioned methods in decision-making processes, 74% (out of all) of the respondents indicated an increase in the quality level of products, and 39% of respondents indicated the enhancement of the pro-ecological impact of products on the natural environment. Research limitations/implications: Most of the analysed enterprises from SMEs are tried integrating qualitative-environmental actions as part of improving the quality of products. This approach is crucial when improving the quality of products in SMEs. Practical implications: It is necessary to develop a multidimensional modl enabling the optimization of decision-making processes with the possibility of making full use of the available instruments for improving the quality of the product in such a way as to meet the rapidly changing requirements of stakeholders. Originality/value: The article has cognitive value for development of knowledge, science, quality, and environmental in the area of management of products.

Purpose: The basic purpose of research was to determine the causes of making the decision that manufacturers on their way to improve the quality of their products. Design/methodology/approach: The research method applied in article is mainly standardized survey research making based on survey conducted in contact and remote way conducted in 78 enterprises in south-eastern Poland. The research process also accompanied analysis of thesource documentation. Findings: It was concluded that decision during improving quality of the product were making mainly in simultaneously with considering customers' requirements of the customers about the quality of the products and the impact of products on the natural environment. Research limitations/implications: Most of the verified enterprises from SMEs are tried integrating qualitative-environmental actions as part of improving the quality of products. This is a favorable condition for further research, so that it is possible to adjust the quality and environmental approach when improving the quality of products in SMEs. Practical implications: Discussion of the results of research have a series of practical implications mainly for product management staff. Especially in organizations that designed new products or also in significant modification of these products. Social implications: Building awareness improves not only quality of products, but also simultaneously in line with sustainable development, including in improving environmental aspects. Originality/value: The article has cognitive value for development of knowledge, science, quality, and environmental in the area of management of products.

Dokonano analizy wzajemnego wpływu kryteriów jakościowo-środowiskowych podczas doboru farb przemysłowych mających zastosowanie w technice tampondruku. Analizę zrealizowano w ramach zaproponowanego przekształcenia metody Dematel (decision making trial and evaluation laboratory method). Opracowana metoda pozwoliła zweryfikować wzajemne relacje pomiędzy oczekiwanym poziomem jakości i negatywnym wpływem na środowisko naturalne dla wybranych farb przemysłowych. Na ich podstawie dobrano farbę spełniającą oczekiwania klienta i przyjazną środowisku.

The com. inks used for pad printing were assessed by modified decision-making trial and evaluation lab. method (Dematel) to det. The mutual relations between the expected quality level of the paints and their neg. impact on the natural environment. On the basis, the paint expected by the customer and environmentally friendly was selected.

Wraz ze wzrostem wymagań stawianych wytwarzanym konstrukcjom, powłoki ochronne nabrały większego znaczenia. W przypadku tłoka powłoka ochronna w postaci wytrzymałej mechanicznie warstwy grafitowej na płaszczu wyrobu ma zmniejszyć tarcie między pracującymi powierzchniami. Celem badań było zdiagnozowanie powierzchni płaszcza tłoków aluminiowych poddawanych przemysłowej obróbce powierzchni w ramach chemicznego procesu grafitowania. W ramach realizacji celu określono źródła niezgodności powstające w procesie grafitowania odlewów. Wykorzystano w tym celu i zintegrowano wybrane techniki zarządzania jakością. Jak dotąd w przedsiębiorstwie nie przeprowadzano pogłębionych analiz jakościowych względem procesów chemicznych. Zastosowana sekwencja wzajemnie uzupełniających się narzędzi stanowiła nowość w kontekście doskonalenia procesów chemicznych. Działania te przyczyniły się do znacznego zmniejszenia liczby wyrobów niezgodnych.

The expert discussion and the process failure mode and effects anal. method were used to test the correctness of the graphite layer application on the Al piston skirt. All non-conforming products after the graphitization process were analyzed and the sources of non-compliance arising in the process were identified. The insufficient homogenization of the graphite paste and lack of the efficient process control resulted in the decreased quality of the final products.
