Purpose: The study explored how supplier evaluation, selection, development and segmentation affect supply chain performance in pharmaceutical organizations. It also determined the moderating influence of top management support on the link between supply chain performance and organizational performance. Design/methodology/approach: The research philosophy of this study was positivism, leading to the adoption of a quantitative research method. Empirical data were gathered from a significant sample of supply chain experts at leading pharmaceutical companies in South Africa. Data collection scales were derived from existing studies. The collected data were analysed using structural equation modelling. Findings: The results confirmed the validity of the proposed model, which is based on selected criteria (latent variables). This study emphasizes the crucial influence of supplier evaluation, selection, development and segmentation on supply chain performance in pharmaceutical organizations. The research shows a positive correlation between supply chain performance and organizational performance, with top management support playing a moderating role. Originality/value: The study’s originality and value stem from its thorough examination of how supplier relationship management practices affect supply chain performance and organizational performance in the pharmaceutical industry of South Africa. Furthermore, the research adds to the current body of knowledge by considering the moderating influence of top management support on the link between supply chain performance and organizational performance.

The main purpose of this study is to systematically examine the extant literature on the intersectionality of e-filing and tax compliance in the current Industry 4.0. This research utilized data from the Scopus database during the period between 2020 and 2025. The sample size of 83 articles extracted from Scopus according to the PRISMA methodology was subjected to bibliometric analysis. The analysis of the data revealed the publication trend from 2020 to 2025, leading (top 10) countries, most productive research institutions, leading articles, co-citations, most cited researchers, and emerging trends through co-occurrences of keywords. It is concluded that there is a growing global interest in digital tax systems since e-filing contributes to enhanced efficiency and compliance, while its impacts vary significantly across demographic, institutional, and technological contexts. The contribution of this study was linked to its novelty in addressing the intersectionality of e-filing and tax compliance in an attempt to inform policy and practice.
