Data Sources and Metrics
The 5th edition of the Research.com Best Business and Management Scientists in South Africa Ranking relies on a comprehensive aggregation of bibliometric data primarily sourced from OpenAlex and CrossRef, alongside multiple other reputable data repositories. These platforms provide extensive citation records and publication metadata, forming a robust foundation for the evaluation process. The bibliometric data that underpin the citation-based metrics used in this ranking were collected on 2026-01-12, ensuring the most current and relevant data snapshot for analysis.
A key metric employed to determine a scientist’s position in the ranking is the D-index (Discipline H-index). This refined bibliometric indicator focuses exclusively on papers and citation metrics relevant to the examined discipline—in this case, Business and Management—thereby offering an accurate measure of a researcher’s impact and productivity within their specific field.
Scope of Research Considered
The foundation of the ranking is a thorough examination of 279,971 scientist profiles identified from a diverse range of bibliometric data sources, encompassing all scientific disciplines. Specifically within the Business and Management domain, the study focused on 4,000 scientists. To qualify for inclusion, a scientist had to demonstrate a D-index of at least 30 and have the majority of their tier publications rooted in Business and Management.
In addition to bibliometric thresholds, researchers’ professional awards and recognized achievements within Business and Management were carefully considered to ensure a comprehensive assessment of their standing in the field. The D-index threshold is calibrated as an increment of 10 relative to the total number of scholars estimated within each discipline to systematically capture the top 1% of leading experts. Furthermore, to ensure disciplinary alignment, a scientist’s general H-index and D-index must exhibit a proximity of no more than 30%, reinforcing that the ranking represents specialists with a strong focus in Business and Management.
Verification Practices and Methodological Rigor
Recognizing the limitations of raw bibliometric data as an absolute measure of scholarly output, the Research.com team undertook meticulous manual verification of all scientist profiles. This process involved cross-referencing against a broad spectrum of trustworthy publication sources to validate accuracy and reliability. While the quantity of papers published in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, it remains an important secondary signal reflecting their contribution to advancing knowledge in their discipline.
The ranking itself is established using each researcher’s D-index based on information gathered from OpenAlex and CrossRef, acknowledged as two of the most prominent and comprehensive bibliometric databases accessible to the global research community.
