The research aims to develop a systemic approach to state and entrepreneurial management of product quality in developing countries. To this end, empirical evidence on quality management in developing countries in 2026 from regions such as Europe, Central Asia, East and South Asia, Latin America and the Caribbean, the Middle East and North Africa, and Sub-Saharan Africa is systematized and reinterpreted from the perspective of facilitating the transition to ISO 9001 and ISO 14001 standards. Using correlation analysis, the authors quantitatively assessed the contribution of various legal and corporate responsibility measures to aligning national products of developing countries with international quality standards. The principal conclusion of this research is that the effectiveness of quality management measures varies significantly across domains (state and entrepreneurial governance) and across world regions. In light of this, the proposed systemic approach to product quality management is distinguished by the integrated implementation of measures in state and entrepreneurial governance and by a focus on those measures that yield the highest returns in terms of product quality. This approach ensures an optimal balance between legal and corporate responsibility in managing product quality.
The increasing complexity and dynamism of market demands necessitate rapid and efficient processes in manufacturing. 3D printing enables reduced prototyping time which can help companies to survive and be competitive. There are different additive manufacturing techniques such as fused deposition modeling (FDM), laminated object manufacturing (LOM), selective laser sintering (SLS), stereolithography (SLA) etc. Also, there are different 3D printers at the market. However, selecting an optimal 3D printer requires careful consideration of technical, economic, environmental, and performance criteria. This study employed the analytical hierarchy process (AHP) to evaluate and rank four 3D printer models available in Serbia based on five criteria. Sensitivity analysis confirmed the robustness of the decision-making model, with the highest-ranked alternative consistently maintaining its position under varying weight scenarios. The results demonstrate the utility of AHP in providing structured, reliable guidance for 3D printer selection, enabling manufacturers to enhance their prototyping capabilities efficiently.
This study examines the relationships between customer service, efficiency, electronic satisfaction, and electronic trust in digital marketplaces, focusing on the mediating role of satisfaction. Data were collected from 326 respondents using purposive sampling and analyzed with Partial Least Squares Structural Equation Modeling. The findings indicate that customer service and efficiency significantly enhance satisfaction, which in turn positively influences trust. Satisfaction also mediates the relationships between customer service, efficiency, and trust, highlighting its critical role in building consumer confidence. These results emphasize the importance of responsive customer support and efficient platform design in fostering satisfaction and trust. Businesses should invest in improving service quality, userfriendly interfaces, and secure transaction systems to enhance customer experiences and loyalty. This study provides insights into trust-building mechanisms in digital marketplaces and offers recommendations for businesses and policymakers to promote customer satisfaction and trust in competitive and evolving digital environments.
This paper presents an analysis of the learning potential in Social Network-based Education (SNE) versus Project-Led Education (PLE). Analysis is based on data collected through the questionaires responded by students over twelve years of implementation of SNE. The results show that students generally perceived SNE as offering greater learning potential than classical PLE. The preference for SNE was also associated with higher perceived learning and with reported gains in personal growth and entrepreneurship. In this way, introduction of SNE, as an alternative educational methodology, is justified.
The use of process improvement methodologies to assist and support the improvement of processes has proven to be an important mechanism for effectively implementing these improvements. However, there is difficulty in choosing the best methodology and to ensure that it will lead to the best improvement results. In this sense, the research questions of this work can be formulated as the following: H1-There are differences between the major process improvement methodologies and gaps not covered by them; H2-A new process improving methodology may mitigate the gaps identified in the existing process improvement methodologies. Comparing the main process improvement methodologies available in the literature, namely, PDCA, Six Sigma, DMAIC, QC Story, 8D, TOC and Lean, it was proven the research question H1. To validate the research question H2 a new process improvement methodology, the MAPIC, was then proposed and compared with the other methodologies. From a theoretical view point, the research question H2 was validated, because the MAPIC covers the existed gaps from the others methodologies, namely, that there is no phase to promote proactive continuous improvement, nor to validate the proposed improvement before its implementation. As for its practical validation, the MAPIC is being applied in a case study and the results will be presented in further work.
