Digitization and the internet are new phenomena which have greatly changed the way in which modern-day businesses are run. Enterprise resource planning (ERP) is one such system developed as a result of digitization in order to improve firm supply chain efficiency. This study investigated the relationship between digital and sustainable supply chain (in this case the ERP system) and firm competences of supply chain management. 33 respondents from e-commerce firms volunteered to take part in the data collection process of the study, with a majority of them being information technology (IT) managers. The hypothesized relationships were analyzed using structural equation modelling (SEM). Findings of the study depict that all the hypothesized relationships were significant (p<.001) at the 1 % level of significance, implying that there exists a positive effect of the ERP systems on firm performance.

Digital transformation has a considerable impact on state institutions, forcing organizations and professionals to adapt to technological advancements. The objective of this study was to analyze the relationship between digital transformation and the job performance of employees at a hospital in the Junín region of Peru. The research is basic in nature and was developed using a quantitative approach with a correlational level. The population consisted of 552 administrative workers, and data was obtained from a sample of 227 employees who perform administrative activities within the hospital. Data analysis included descriptive statistics and the use of structural equation modeling with PLS -SEM estimation, employing SmartPLS 4.0 software. The results showed a positive and significant relationship between digital transformation and job performance. The dimensions of people, technology, processes, and quality showed significant effects on job performance, with statistically significant values (p < 0.05), confirming the robustness of the proposed structural model and its adequate fit. It is concluded that digital transformation significantly influences the job performance of administrative workers in the healthcare sector, contributing to process optimization, the strengthening of job skills, and improved organizational productivity. These findings highlight the importance of promoting comprehensive digital transformation strategies focused on human capital development and institutional efficiency.

This research examines the links between customer perceived expectations, customer perceived experience, and customer satisfaction in the United Arab Emirates' digital solution in the telecommunications industry. The research takes a positivist philosophical perspective and uses a quantitative data analysis strategy to sample 130 clients who utilize the digital solution of the telecommunications sector in the United Arab Emirates. Exploratory component analysis and multiple regression analysis were used to evaluate and validate the validity of the suggested scales and the research model's linkages. The research discovered a strong correlation between customer expectation and customer experience and the degree of satisfaction of individuals in the United Arab Emirates due to their use of or engagement with digital solutions of the telecommunications sector, independent of generational differences. The study's findings are entirely consistent with the Expectancy-Disconfirmation and Evaluation Congruity Theories.
