Purpose: This study aims to assess the microbiological quality and risks associated with nonregulated lakes used for recreational and economic purposes. It highlights the potential risks these lakes pose to public health, especially in terms of waterborne diseases, due to fluctuations in water quality influenced by seasonal variations, human activities, and environmental factors. By evaluating the microbiological contamination levels of lakes that are not part of the formal monitoring system, this research seeks to fill a gap in understanding the risks posed by these bodies of water. Design/methodology/approach: The research employs a combination of water sample collection and microbiological analysis to determine the contamination levels of Enterococcus spp. and E. coli in various water samples taken from a non-regulated lake (Wyspowo Lake). The study compares contamination levels in nearshore and lake center areas during different months to assess variability in water quality. Statistical analysis was performed to determine the significance of differences between sampling sites. Findings: The study found that the water quality in Wyspowo Lake generally met the acceptable bathing water quality standards. However, exceedances of Enterococcus spp. counts were recorded, particularly for two shore samples collected in June and five collected in July. Shore samples consistently showed higher bacterial levels than samples collected from the lake center, especially for Enterococcus spp. These findings highlight the need for increased monitoring of non-regulated lakes to protect public health. Research limitations/implications: The study is limited by seasonal sampling and the absence of continuous monitoring. Future research could involve more frequent sampling and explore the effects of local human activities on water quality. Practical implications: Improved monitoring systems for non-regulated lakes are essential for protecting public health. The study suggests integrating quality and risk management strategies into local monitoring practices. Social implications: The study has significant social implications as it highlights the potential health risks posed by non-regulated lakes, which are often frequented by local communities for recreational purposes. By improving water quality monitoring and public awareness, the research could contribute to better public health outcomes and foster a culture of responsible recreational use of natural resources. Additionally, it could inform local policy decisions related to water management and environmental health, ultimately enhancing the quality of life for people living near these lakes. Originality/value: This article provides original insight into the microbiological quality and risk assessment of an unregulated lake. It adds value to this field by addressing the microbiological safety of lakes not covered by official regulatory systems and proposing practical solutions for improving water quality monitoring and risk management.

The article discusses what is the G8D method, focusing on the fifth discipline of this method, D5, which involves the selection and verification of permanent corrective actions for root causes and escape points. The rationale for applying the G8D method and using the D5 discipline of this method was analyzed for the case of a NOK part, specifically a part with an undrilled hole. The algorithm that must be applied to correctly go through all the steps of the D5 discipline has been presented, in order to obtain verified corrective actions both for the point in the process where NOK parts are produced and for the control point where NOK was not detected. The practical application of this discipline for selected initial conditions (the transition through disciplines D0-D4), as well as the solution for the problem of producing defective products that protect the production system from further manufacturing of such parts has been presented. In construction literature, a similar approach is applied in the quality management of industrial prefabricates, where systematic defect analysis leads to the optimization of production processes. The applicability of the D5 discipline and the Poka Yoke method for securing the production station against the possibility of producing a NOK part was presented.

This article presents an example of how to analyze a production process and subsequently translate it into a structured control chart. The chosen case is the production of classic chocolate bars, treated as a model process. The analysis begins with identifying the inputs and outputs of the process, including raw materials, technological data, human resources, machinery, energy, and financial capital. The output is defined as the final product, side products, production losses, and related performance data. Next, the article describes step-by-step stages of the production flow, from raw material acceptance, quality inspection, mixing and refining, through conching, tempering, molding, cooling, quality control, and final packaging. In addition to process mapping, attention is given to resources such as responsible personnel, technical equipment, and required documentation. Risk analysis using FMEA highlights potential failures at each stage and preventive measures. The final step is the construction of a process control chart, which formalizes the objectives, responsibilities, stages, inputs, outputs, and documentation associated with the production. This structured approach demonstrates how a real production process can be visualized with diagrams and then systematically translated into a standardized control card. It provides a practical framework for monitoring, improving efficiency, ensuring quality compliance, and minimizing risks in industrial operations.

The research focuses on evaluating the microbiological quality of trout from aquaculture farms, with particular attention to local practices and their alignment with sustainability goals. Findings: The study revealed that the trout from the examined farms generally met good microbiological quality standards. Specifically, no methicillin-resistant S. aureus or vancomycin-resistant E. faecium and E. faecalis were detected, indicating effective risk management. However, Salmonella spp. were present in 30.5% of water samples, yet their presence did not significantly affect the contamination levels in fish samples. The highest S. aureus count was found on the skin of rainbow trout (1.5±101 cfu/g), while E. coli was detected on brook trout skin and viscera (11%). Enterococcus spp. were found in 17% of feed samples, but at low concentrations (<10 cfu/g). These results suggest that while overall microbiological quality is satisfactory, ongoing monitoring and adherence to good management practices are crucial for maintaining safety and quality in aquaculture. Research limitations/implications: One limitation of the research is the geographical focus on aquaculture farms within the "Dolina Słupi" Landscape Park, which may limit the generalizability of the findings to other regions or types of aquaculture systems.

Purpose: The purpose of this paper is to assess the microbiological safety of aloe-based dietary supplements available on the Polish market. The study investigates how the form of the aloe supplement (juice vs. capsules) and the storage time affect microbial contamination levels, emphasizing the importance of quality management and risk management in ensuring the safety of plant-based supplements. Design/methodology/approach: The study focused on assessing the microbiological stability of 68 aloe-based dietary supplements, including Aloe vera juice and gel-shell capsules, at two key time points: immediately after opening (time 0) and at the final storage period (time K). Microbiological analysis included testing for the presence of aerobic mesophilic bacteria, yeasts, molds, Staphylococcus aureus, and Escherichia coli, alongside an evaluation of the active acidity and microbiological stability in the juice preparations. The research methodology emphasized a comprehensive laboratory-based approach to evaluate the impact of the supplement form (juice vs. capsules) and storage duration on microbial contamination. By focusing on the end-user stages, the study indirectly addressed risk management by identifying potential contamination risks linked to product form and storage. Additionally, quality management principles were applied through the systematic assessment of supplements' compliance with microbiological safety standards. Findings: The study found that S. aureus and E. coli were absent in all samples, with 18% of the samples free from any microbial contamination. Aloe capsules were more prone to fungal contamination compared to juices. Juices demonstrated greater microbiological stability, with approximately 19% stability compared to around 11% for capsules. These findings underscore the importance of rigorous quality control to ensure the microbiological safety of aloe supplements and highlight the need for ongoing post-market monitoring to mitigate potential health risks. Research limitations/implications: The study focused specifically on aloe supplements from the Polish market, which may limit its generalizability to other types of plant-based supplements. Future research could broaden the scope to include other popular plant supplements, such as young barley, to compare microbiological stability and safety across different categories of plant-based products. This would provide a more comprehensive view of potential risks and quality control measures needed for various supplements. Practical implications: The research underscores the need for enhanced quality control measures during the production, storage, and distribution of aloe supplements. Manufacturers should implement risk management strategies to reduce contamination risks, particularly in capsule-based products, and improve hygiene practices to meet safety standards.

Purpose: The idea of the study is to understand fluctuation in quality management depending on organizational context. The primary purpose of this article is to analyze changes in quality management in four countries grouped in V4 (The Visegrad Group) in the prism of macroeconomic crises, over the last five years. The following research question was formulated: What influences market saturation with a formal approach to quality management (ISO 9001 certificates), and when? Design/methodology/approach: The considerations are based on a systematic literature review (SLR) and an analysis of the long-term data of ISO survey – certifications. The data was compared among V4 countries and an attempt was made to relate the results to economy-wide indicators, especially in turbulent environments. Findings: The results show no clear and unidirectional relationships between the number of ISO 9001 certifications and macroeconomic data. This was identified for the V4 group as a whole and for individual countries, as well. Implementation of the QMS is an individual decision of each organization, depending on closely related microeconomic factors. Research limitations/implications: Research findings always represent a slice of a larger reality. In that research paper limitations concern: the period of analysis, literature review in English and supplemented locally in the native languages, focusing on the V4 area. Findings implicate quality management’s perceptions need to adjust the lens to understand macro numbers of certificates by the circumstances and adjust micro decisions in organizations in the QM area depending on the crisis phase on the market.Originality/value: The article analyses certification data in previously unpresented form. Results were compared between V4 countries in the prism of times of crisis with an indication of certificate saturation rates and an attempt to explain macroeconomic fluctuations. The research results are helpful for researchers exploring quality management issues, and all organizations that can relativize the importance of quality management.

Maintaining a strong market position is a significant challenge for manufacturing companies, requiring them to meet customer demands through high-quality products while balancing the associated costs. Proper quality management is essential but incurs substantial costs, particularly in terms of production maintenance and prevention. This paper explores the relationship between quality costs and business growth, emphasizing the need for manufacturers to constantly evaluate financial performance in relation to unit production costs and quality maintenance expenses. The study highlights that integrating quality into the production process is a key strategy for preventing business growth inhibition due to escalating quality costs. While investing in quality management can drive business development by improving product quality, customer satisfaction, and operational efficiency, poor management of quality costs can hinder profitability and growth. The findings suggest that strategic handling of quality costs can foster sustainable growth, whereas mismanagement may lead to competitive disadvantages.

In today's competitive business environment, effectively analyzing, evaluating, and resolving product quality problems is critical to maintaining customer satisfaction, reducing financial losses, and preserving a company's reputation. This study prioritizes internal and external quality problems in paperboard packaging using selected quality management tools. Product quality problems are categorized based on their frequency of occurrence and financial losses. Three quality management tools are used: the ParetoLorenz diagram, the matrix data analysis diagram, and the box plot. The Pareto-Lorenz diagram identified the key quality problems that generate the highest number of events and the greatest financial losses, consistent with the 80/20 rule. The matrix data analysis diagram divided the quality problems into four groups based on their combined impact, indicating critical problems for both categories. The box plot identified outliers and extremes, revealing quality problems with significantly higher frequency and financial impact than others. All quality tools used identified the overprint complaint with code 403 as critical. The results highlight the effectiveness of the quality management tools used in prioritizing product quality problems.

Cel: Celem artykułu jest analiza różnych, spotykanych w literaturze, podejść do ewolucji zarządzania jakością i zaproponowanie autorskiego pogłębionego podejścia do tej problematyki. Uwaga autorów koncentruje się na różnicach między poszczególnymi generacjami zarządzania, ze szczególnym uwzględnieniem roli, jaką odgrywa w tej ewolucji TQM. Asumptem do zainteresowania się tym problemem było pojawienie się w literaturze naukowej koncepcji jakości 4.0 oraz jakości 5.0, choć do tej pory w publikacjach naukowych nie numerowano wcześniejszych etapów rozwoju zarządzania jakością. Projekt badania/metodyka badawcza/koncepcja: Analiza opierała się na przeglądzie literatury i dostępnych raportów z zakresu aktualnego stanu wiedzy w obszarze zarządzania jakością. Szczególną uwagę zwrócono na publikacje na temat jakości 4.0 i 5.0 zawarte w naukowych bazach danych. Wyniki/wnioski: Autorzy zidentyfikowali atrybuty przypisane każdej z generacji zarządzania jakością. Określono miejsce koncepcji TQM w ewolucji zarządzania jakością oraz jakości 4.0, rozpoznanej jako nowa generacja TQM, istotnie rozbudowana poprzez digitalizację danych. Zidentyfikowano też wyzwania stawiane przed kształtującą się dopiero generacją zarządzania jakością określaną jako Jakość 5.0 - Sustainable Ouality. Oryginalność/wartość poznawcza: Praca przyczynia się do lepszego zrozumienia ewolucji zarządzania jakością, szczególnie w kontekście problemów związanych z numerowaniem generacji oraz roli TQM w tej ewolucji. Analiza atrybutów poszczególnych generacji oraz ich wpływu na jakość życia wnosi nowe spojrzenie w tym obszarze nauk o zarządzaniu i jakości. Oryginalność polega również na szerokim podejściu do TQM jako filozofii projakościowego zarządzania, co umożliwiło traktowanie jakości 4.0 i 5.0 jako rozbudowy holistycznego podejścia do jakości charakterystycznego dla TQM, którego umownym „punktem startowym" jest jakość 3.0. Oznacza to odejście od tak często spotykanego wąskiego traktowania TQM jako konkretnej metody zarządzania, która powinna już odejść do „lamusa" historii zarządzania jakością.

Purpose: The purpose of the study is to analyze various approaches to the evolution of quality management and to propose an original, in-depth approach to this issue. The authors focus on the differences between individual generations of quality management, particularly emphasizing TQM's role in this evolution. Design/methodology/approach: The analysis was based on a review of the literaturę and available reports on the current State of knowledge in quality management. Particular attention was paid to publications on quality 4.0 and 5.0 contained in scientific databases. Findings/conclusions: The authors identified attributes assigned to each generation of quality management. The place of TQM in the evolution of quality management and quality 4.0 was determined and recognized as a new generation of TQM, significantly expanded through data digitization. Challenges faced by the emerging generation of quality management known as Quality 5.0 - Sustainable Ouality were also identified. Originality/value: The work contributes to a better understanding of the evolution of quality management, especially in the context of problems related to generation numbering and the role of TQM in the evolution. The analysis of the attributes of individual generations and their impact on the quality of life brings a new perspective in this area of management and quality Sciences. The originality also lies in the broad approach to TQM as a philosophy of pro-quality management, which madę it possible to treat quality 4.0 and 5.0 as an extension of the holistic approach to quality characteristic of TQM, the conventional "starting point" of which is quality 3.0. This means a departure from the so-often-seen narrow approach to TQM as a specific management method, which should now become a thing of the past in the history of quality management.

Purpose: Identification of scientific fields and disciplines with theoretical and practical applications in quality management. Design/methodology/approach: Using the method of analysis and logical construction, the research questions sought to be answered: Which scientific fields and scientific disciplines are applicable to quality management theory and practice? What is the scope of scientific fields and disciplines in quality management theory and practice? Findings/conclusions: Scientific disciplines can be classified (in general and specific classification) according to the existence of links with the TQM concept and the ISO quality management system. The scientific disciplines with the greatest links to the TQM concept and the ISO quality management system are management and quality sciences, psychology, economics and finance. The other scientific disciplines (sociology, philosophy, mathematics and computer science) have the least connection with the TQM concept and the ISO quality management system. The greatest diversity characterises the quantitative structure of scientific disciplines in the social sciences. Common to the principles (excellence and TQM) and requirements of the ISO quality management system are the same scientific disciplines (management and quality sciences, psychology, economics and finance). Research limitations: EN ISO 9001 without taking into account other ISO systems in the area of quality management. Practical implications: Defining the limits of interdisciplinary knowledge in quality management as a basis for realising the concept of the intelligent organisation. Originality/value: To indicate the perspective of empirical research on the impact of interdisciplinary knowledge on the achievement of: (a) quality objectives, (b) higher efficiency in quality management, (c) desirable organisational behaviour.
