Enterprise Resource Planning (ERP) systems represent an important technological infrastructure for enhancing operational efficiency and strategic decision making in various industries. This study examines the key determinants influencing the adoption of ERP systems, with a particular focus on organizations operating in the manufacturing and service sectors in the Western Balkans region. In order to empirically evaluate the proposed conceptual framework, Partial Least Squares Structural Equation Modeling (PLS-SEM) and Fuzzy Set Qualitative Comparative Analysis (fsQCA) were employed. In this way, both linear relationships and configuration pathways underlying ERP implementation behavior were captured. The results of the PLS-SEM analysis show that constructs such as work compatibility, perceived usefulness and external factors are statistically significant predictors of users’ attitudes towards using ERP systems. In addition, a significant relationship was found between attitude and actual use of ERP systems, with user experience serving as a moderating variable. Notably, the multi-group analysis revealed no significant differences in intentions, attitudes or preferences between users from the manufacturing and service sectors. The results of the fsQCA study also show that work compatibility and perceived usefulness are the core present conditions necessary for effective ERP adoption. This study contributes to the existing literature by integrating multiple analytical approaches to explore the complexity of ERP usage. Additionally, it provides practical insights for enterprise managers, ERP vendors and policymakers.

Occupational injuries remain a significant issue in European countries, affecting both worker safety and broader socio-economic outcomes. This study groups European countries into homogeneous categories based on workplace injury levels from 2014 to 2023. The analysis uses secondary data from Eurostat, including indicators on fatal and non-fatal workplace accidents within aggregated sectors: agriculture, industry and construction (excluding mining), and business economy services. To achieve the research objective, K-means cluster analysis was applied after data standardisation using Z-score normalisation. The results show substantial variability in occupational injury levels across countries, with particularly high dispersion for non-fatal injuries. The clustering identifies two distinct groups of countries, representing relatively safer and less safe working environments. While most countries show consistent classification across both fatal and non-fatal injury models, a significant number display discrepancies, suggesting that these indicators capture different aspects of workplace safety.

As integrated business information systems that encompass the business processes of the entire company, Enterprise Resource Planning (ERP) systems store vast amounts of sensitive organisational data. Consequently, their security and reliability have become critical concerns in modern business environments. In addition to technical security ensured through technical checks, users’ perceptions of ERP security play an essential role in the success of ERP implementation and use. This study examines the moderating effect of users’ perceived security and reliability (PSR) of ERP systems on the relationship between attitude to use (AT) and actual usage (AU) of ERP systems in process and discrete industries, based on a sample of 98 experienced ERP users. In the first phase, the research model was examined without the moderating effect, and the results showed a positive and statistically significant relationship between AT and AU (path coefficient = 0.460; p = 0.000; R² = 0.212). In the second phase, the research model included the moderating effect of PSR, and the results showed a positive and statistically significant moderating effect (path coefficient (AT → AU) = 0.620; p = 0.000; path coefficient (AT × PSR → AU) = 0.336; p = 0.001; R² = 0.374). The results indicate that when users perceive the ERP system as secure and reliable, this leads to more effective adoption and use. From a theoretical perspective, this study highlights ERP system security as a sociotechnical construct rather than solely a technical one. The findings provide valuable practical insights for ERP vendors, managers, and consultants, highlighting that companies should consider how users perceive and understand ERP security measures to improve ERP acceptance.

An enterprise resource planning (ERP) system is vital for managing business operations in today’s business world. However, the mere implementation does not ensure that this system is used effectively. Therefore, monitoring the usage of the ERP system is essential for fully realising its potential. This study examines the key factors driving the actual usage of ERP systems through a quantitative analysis based on empirical research. Relevant respondents from Western Balkan countries with ERP system experience were selected to ensure the results’ high reliability and relevance. Following the data collection process, which combined LinkedIn-based recruitment with a snowball sampling approach, 139 valid and fully completed questionnaires were retained. An integrated methodological approach was employed, combining partial least squares structural equation modelling (PLS-SEM), artificial neural networks (ANNs), and importance-performance map analysis (IPMA). The results show that Work Compatibility is the most important variable influencing ERP usage, followed by external factors and Perceived Usefulness. Study findings offer valuable insights by improving theoretical understanding and highlighting practical implications, indicating that managers should actively address these influential factors for successful ERP implementation and optimal utilisation of ERP systems.

COVID-19 had a profound and far-reaching impact on digital transformation across various sectors and countries. However, it remains unclear whether it reduced structural differences in technology adoption or reinforced existing digital divides. This study examines ERP adoption dynamics across countries, including the effect of COVID-19. Using secondary data from the Eurostat database for the period 2015-2025, the study applies K-means clustering to examine cross-country differences in the share of enterprises adopting ERP systems for functional information exchange. Cluster analysis identified three statistically distinct groups: digital leaders, followers, and late adopters. Digital leaders maintain consistently high ERP adoption levels throughout the observed period. Digital followers start at a lower level than digital leaders but show the most dynamic growth. Late adopters display the lowest ERP adoption levels throughout the decade. Descriptive trends indicate a post-pandemic acceleration, suggesting COVID-19 as a potential catalyst fr intensified ERP adoption. Based on the study’s outcomes, policy implications are suggested and future research directions are proposed.

Enterprise Resource Planning (ERP) system quality plays a critical role in improving organi-sational efficiency by integrating business processes and enabling real-time information exchange. However, perceptions of ERP system quality may vary across different industrial contexts. This study examines whether statistically significant differences exist in perceived ERP system performance between users in discrete and process industries. Empirical data were collected through an online survey of 100 ERP users employed in enterprises operating in Serbia. ERP system quality was mea-sured by data search efficiency, system loading time, data downloading, document creation, and task execution. The analysis of variance (ANOVA) method was applied to test differences in user percep-tions between the two industry types. The results indicate statistically significant differences in per-ceptions related to data search efficiency and system loading speed, while no significant differences were found for data downloading, document creation, and task execution. The study contributes tothe literature by providing empirical evidence on industry-based differences in ERP system perfor-mance perceptions. From a practical perspective, the results highlight the importance of adapting ERP system design and configuration to the specific operational needs of different industrial envi-ronments. Future research could extend the analysis by including additional ERP quality dimensions and a broader sample.
