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.

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: The aim of this article is to perform a multivariate statistical analysis of package filling process results for predictive production and quality management. The article presents a case study from the food industry that demonstrates the feasibility of using an appropriate set of control charts for ongoing and predictive production and quality management. Design/methodology/approach: The objectives of the article were achieved through the use of Statistical Process Control (SPC) tools, in particular control charts. The control charts used include both traditional numerical chart such as Xbar and S and special charts such as MA, EWMA, CUSUM and GCC. Findings: SPC tools such as control charts have proven to be extremely useful in monitoring the filling process and predicting future performance. By carefully monitoring the process using traditional and special control charts, it is possible to quickly identify small, gradual or sudden changes that may occur in the production process before the process gets out of control. Research limitations/implications: The research will continue by identifying additional factors that affect the quality of the product, particularly as regards precision and accuracy of dosing, and by evaluating the process studied in terms of its ability to meet customer requirements. Other statistical techniques will also be used to identify patterns and relationships between the various parameters of the process under study. This approach will provide more comprehensive information about the quality and ability of the dosing process to meet customer requirements.. Practical implications: By implementing the right SPC toolkit and using dedicated software that significantly speeds up data analysis, companies can effectively control the quality of the production process. By monitoring the behaviour of the process over time and detecting small changes and trends, it is possible to respond to potential problems in advance. Originality/value: This article is intended for production process managers who want to learn how to use the right SPC toolkit to obtain information about the process behaviour and the moments when intervention actions should be taken.

Purpose: The main purpose of the study was to develop and demonstrate a concept enabling application of popular and commonly available online forms combined with a spreadsheet to support data collection and processing under the ABCD (Suzuki) method. Design/methodology/approach: The factors which determine the various ways in which the method in question is applied were first identified, and then it was established which of them affected the manner in which the form to be filled by experts is designed. Different variants of the method were identified on such a basis. For individual variants, the possibility of using different types of questions was discussed by considering the features available in the most popular and free-of-charge solutions enabling online forms to be developed. Diverse data layouts were also identified to establish the frameworks in which data are represented in spreadsheet files. Solutions which make it possible to automatically produce the consolidated reports required for purposes of the ABCD method were identified for each of the data layouts originally defined. Findings: When combined with a spreadsheet, popular online forms enable highly efficient data collection and processing with the ABCD method in use. Where the said method is applied according to the variant in which every cause is rated, an adequate data collection form can be created using both the online form solutions subject to analysis. If the method is applied according to the variant in which every rating must be used precisely once, developing a useful tool becomes significantly more complicated. Where this is the case, one can create a suitable form to validate the input data only by using the solution delivered by Google. Additionally, the layout of such a form must be reversed compared to the traditional form functioning under the ABCD method. Considering the diverse variants of the ABCD method linked with various kinds of questions used to build the form, 3 different layouts of the data collected by means of a spreadsheet were identified. With respect to each of them, one can devise a solution to ensure automated generation of the consolidated reports typical of the method in question. Practical implications: The solution proposed in the paper can be applied in practice while using the ABCD (Suzuki) method. Originality/value: The concept described in the paper is the author’s signature solution.

Purpose: The primary purpose of the article is to present a study whose subject was the assessment of the quality policies implementation in selected enterprises. Design/methodology/approach: The deliberations are based on the related subject literature and an analysis of the long-term survey results. The practical results of the research described in this article are based on a survey of supervisory employees and middle managers, who represented the enterprise by filling out a single survey sheet. The survey was conducted in 2015-2022 among 240. enterprises operating in Poland. During the survey, independence in setting quality policy was identified for 237. enterprises. These were manufacturing and service enterprises from various industries. Enterprises were selected on the basis of proposals issued to conduct a survey. The surveyed group does not have the character of a research sample. When analyzing the survey results, no parameter estimation was made on the population of Polish enterprises. The quality policy survey sheet described 35. aspects (behaviors) characteristic of a strongly quality-oriented organization, close to the TQM philosophy (The article contains results for only 10 aspects). Respondents indicated how the behavior described in the survey is characteristic of the organization where they work. The described aspects were rated by respondents on a scale of 1 to 5. The scale adopted reflects the strength of the similarity of the behavior described in the survey to the situation in each organization. Findings: In close to every studied Quality Policy aspects, higher score was received by companies where the standards are imposed by foreign management boards. This is connected obviously not just with standards but also with the governance. The reasons for this should become a subject of further analyses. A certain potential can be observed for national companies relating to the foreign good practice implementation. Originality/value: Knowledge of quality management issues has been increased. The article raises the issue of implementing quality policies in companies. The quality policy was characterized by selected aspects. An evaluation of these aspects in selected enterprises was carried out, and differences dividing quality policies among independent and dependent enterprises in the implementation and supervision of quality standards were identified.

A turbulent manufacturing market, especially in the metal industry, determines the quality of products and the level of production efficiency, which contributes to a company's market position and competitiveness. The aim of the study was to develop a model to define a manufacturing company’s current market position using KPIs in relation to a key product - gearbox casting. The company's position was defined in terms of the relationship occurring between technological capabilities and market position. An additional aim of the study was to identify critical determinants and, ultimately, to identify conditions for strengthening market position. As a test of the proposed model, the position of the analysed company (in terms of technological capabilities and market position) was defined as “Search for occasions”- box 9 within the 3x3 matrix. Technological determinants that weaken the company’s position (low level of maintenance capacity and long production cycle time) and determinants with a strong negative impact on market position (low level of human resource development) were identified. An element of novelty is the use of KPIs as variables determining the position of the company within the3x3 matrix, which is indicative of a specific technological position in the market. Further lines of research will concern the determination of appropriate KPIs in relation to the identified critical areas of the company. Subsequent steps will concern the implications of the model in relation to the company’s other key aluminium alloy castings.

The Covid-19 pandemic has acknowledged the importance of educational management information systems (EMIS) for quality management (QM) in higher education and set new directions for post-pandemic studies. Successful implementation of QM, however, processes depends mainly on lecturers' perceptions about quality and educational technology. However, higher education lecturers’ profiles regarding these quality perceptions and their commitment to technology acceptance must be investigated more. The aim of research is to analyse the relationship between Education Management Information System (EMIS) and Quality Management (QMAS) to lecturers' Continuance Commitment (CC). In response to this research gap, the researchers identified such profiles using a quantitative survey of 534 lecturers from Indonesian higher education institutions. A seven-point Likert scale was used to measure the respondents' expectations or expression of their perceived experience on all indicators used in the study. The data analyses were descriptive analysis and factor analysis. Based on the seminal work of Roger's diffusion of innovations, technology enthusiasts, visionaries, pragmatists, conservatives and sceptics remain valid in the organisation, and the uptake of educational management information systems is still in the hands of technology enthusiasts and visionaries. Quality management and EMIS acceptance are critical factors that make lecturers willing to continue using the system to support accreditation. These profiles will enable customised training in the recovery after the Covid-19 pandemic.

Pandemia Covid-19 potwierdziła znaczenie systemów informacyjnych zarządzania edukacją (Education Management Information Systems - EMIS) dla zarządzania jakością (Quality Management - QM) w szkolnictwie wyższym i wyznaczyła nowe kierunki badań post-pandemicznych. Pomyślne wdrożenie zarządzania jakością zależy głównie od postrzegania jakości i technologii edukacyjnych przez wykładowców. Należy także dokładniej zbadać profile wykładowców szkolnictwa wyższego w zakresie postrzegania jakości i ich zaangażowania w akceptację technologii. Celem badania jest analiza związku między Systemem Informacji o Zarządzaniu Edukacją (EMIS) a Zarządzaniem Jakością (QMAS) w odniesieniu do ciągłego zaangażowania wykładowców (Continuance Commitment - CC). W odpowiedzi na tę lukę badawczą naukowcy zidentyfikowali takie profile za pomocą ankiety ilościowej przeprowadzonej wśród 534 wykładowców z indonezyjskich instytucji szkolnictwa wyższego. Siedmiostopniowa skala Likerta została wykorzystana do pomiaru oczekiwań respondentów lub wyrażenia ich postrzeganego doświadczenia we wszystkich wskaźnikach wykorzystanych w badaniu. Analizy danych obejmowały analizę opisową i analizę czynnikową. W oparciu o przełomową pracę Rogera na temat dyfuzji innowacji, entuzjaści technologii, wizjonerzy, pragmatycy, konserwatyści i sceptycy pozostają ważni w organizacji, a absorpcja systemów informatycznych zarządzania edukacją jest nadal w rękach entuzjastów technologii i wizjonerów. Zarządzanie jakością i akceptacja EMIS są krytycznymi czynnikami, które sprawiają, że wykładowcy chcą nadal korzystać z systemu w celu wspierania akredytacji. Profile te umożliwią zindywidualizowane szkolenia w zakresie odbudowy po pandemii Covid-19.

This work concerns automation of the training process, using modern information technologies, including virtual reality (VR). The starting point is an observation that automotive and aerospace industries require effective methods of preparation of engineering personnel. In this context, the technological process of preparing operations of a CNC numerical machine has been extracted. On this basis, a dedicated virtual reality environment, simulating manufacturing of a selected aircraft landing gear component, was created. For a comprehensive analysis of the pros and cons of the proposed approach, four forms of training, involving a physical CNC machine, a physical simulator, a software simulator, and the developed VR environment were instantiated. The features of each training form were analysed in terms of their potential for industrial applications. A survey, using the Net Promoter Score method, was also conducted among a target group of engineers, regarding the potential of use of each training form. As a result, the advantages and disadvantages of all four training forms were captured. They can be used as criteria for selecting the most effective training form.

Map portals can facilitate the work of public administration units and improve access to information, although they have to present high material and technical quality. Not without significance are also measures supporting these websites. This paper aims to assess the quality of selected geoinformation websites. The study was carried out in the form of a quality audit with the use of selected web applications provided in a freeware, thin-client model. A comparative analysis was performed on three versions of the geoservice functioning for the Tomice municipality (accessed on 5th July 2023): 1) eMPZP website (https://www.tomice.pl/mpzp/), 2) municipal geoportal (http://www.mpzp.tomice.pl), and 3) municipal map portal (https://sip.gison. pl/tomice). The measurements were taken only once and in an ad hoc manner. The tests were performed in selected quality dimensions: responsiveness, performance, content and hyperlink quality, accessibility for people with disabilities, syntactic code correctness, search engine optimisation (SEO), and usage indicators, with special emphasis on overall quality. The conclusion was that each of the geoportals evaluated presents good quality. However, it would be wrong to compare them in absolute terms, as the quality of these services should be assessed through the lens of the different times in which they operate.

Podmioty, które dostrzegają potencjał analityki internetowej coraz częściej monitorują witryny i aplikacje internetowe, odnotowując wzorce zachowań użytkowników, analizując jakość serwisów oraz poszukując obszarów wymagających optymalizacji. Dojrzała kultura analityczna pozwala skutecznie wykorzystywać dane w procesie decyzyjnym [Röglinger i in. 2012]. Sektor prywatny korzysta z analityki internetowej znacznie częściej i w stopniu bardziej zaawansowanym, w porównaniu do jednostek administracji publicznej, w tym samorządów terytorialnych. Ponadto znacznie częściej wykonuje audyty, których celem jest poprawa jakości posiadanych serwisów internetowych [Alghenaim i in. 2023]. Portal mapowy może wpłynąć na usprawnienie pracy jednostek administracji publicznej oraz zwiększenie dostępu do informacji, jednak musi być on wysokiej jakości merytorycznej i technicznej. Nie bez znaczenia są też działania podejmowane w otoczeniu portalu. Celem pracy jest ocena jakości wybranych serwisów geoinformacyjnych. Badania wykonano w formie audytu jakości, z zastosowaniem wybranych aplikacji internetowych udostępnianych w modelu freeware, thin-client. Analizie porównawczej poddano trzy wersje geoserwisu gminy Tomice (dostęp z dnia 05.07.2023): 1) serwis eMPZP (https://www.tomice.pl/mpzp/), 2) geoportal gminy (http://www.mpzp.tomice.pl) oraz 3) gminny portal mapowy (https://sip.gison.pl/tomice). Pomiary miały charakter jednostkowy typu ad-hoc. Testy wykonano w wybranych płaszczyznach jakości: responsywności, wydajności, jakości treści i hiperłączy, dostępności dla osób z niepełnosprawnościami, poprawności składniowej kodu, stopnia optymalizacji dla wyszukiwarek (SEO) oraz wskaźników użytkowania, ze szczególnym uwzględnieniem jakości globalnej. W konkluzji zwrócono uwagę, że każdy z ocenianych geoserwisów jest dobrej jakości. Błędem jest porównywanie ich w sposób bezwzględny, ponieważ jakość tych serwisów powinna być oceniana przez pryzmat ery w jakiej funkcjonowały.

Conducting research on the quality of service and customer satisfaction is currently necessary for the proper and effective functioning of any organization. One of the organizations that have changed in recent years is petrol stations. In this paper, the Customer Satisfaction Index (CSI) is used to measure the quality of services and customer satisfaction. This research was carried out with the use of a proprietary questionnaire in which the respondents assessed the level of service at petrol stations. The obtained results allowed identifying the most important areas for the customers of petrol stations. In addition, the developed quality map indicated areas that should be given special attention, improved and those that are least important to customers. The conducted analyzes indicate that the CSI method used in this study is a tool that enables the assessment of customer satisfaction in a complex organization such as a petrol station.

Purpose: The main purpose of the research is to devise and present a concept for a solution enabling integration of popular off-the-shelf online forms with a tool aligned with the MiRel concept used for quality measurement by application of the SERQUAL method. Design/methodology/approach: The analysis performed by the author comprised various possibilities of using standard features of popular online forms to store data for purposes of the SERVQUAL method. This involved identification of several potential layouts of the master table where the answers previously received are kept. The analysis concerned the data structure applied in the tool designed, as proposed in the literature, in accordance with the MiRel concept, to support the method in question. The elements identified in this structure were the attributes whose values should be entered directly and manually in tables as well as those whose values should be added automatically on the basis of the answers previously received. Solutions were developed to enable automatic data migration from the master table to the tool’s respective tables. Findings: The data required for purposes of the SERVQUAL analysis, supported by a tool created in a spreadsheet according to the MiRel concept, can be successfully stored by means of commonly available online forms. What proves to be problematic is the impossibility of verifying the correctness of the answers in terms of the relevance of individual dimensions, yet in this respect both the verification and potential adjustment of the answers received can be inherent in the mechanism responsible for data migration from the master table to the tool’s tables. A fully functional solution enabling data to be retrieved from the master table and moved to the tool’s tables can be developed using built-in spreadsheet features only, without the need for any code created in any programming language. Practical implications The solution proposed in the paper can be used in practice when measuring quality using the SERVQUAL method. Originality/value: The concept described in the paper is the author’s original solution.

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.
