Purpose: This study examines the mediating influence of professionalism on the relationship between entrepreneurial passion and success in small and medium-sized enterprises (SMEs) in Nigeria.
Research Methodology: Data were collected from a sample size of 288 SMEs owners in Jos South LGA of Plateau State out of a total population of 1026 SME owners and were analyzed using PLS-SEM version 3.0.
Results: The results of the direct relationships revealed a significant positive relationship between the variables HO1 (? = 0.831, tstat = 20.447, and p-value = 0.000), HO2 (? = 0.882, t-stat = 51.325, and p-value = 0.000), and HO3 (? = 0.168, t-stat = 3.822, and p-value = 0.000). Mediation analysis revealed that EP and ES were mediated by professionalism (HO4, t-stat = 3.817, p = 0.000).
Limitations: This study was limited to EP, ES, and professionalism, and was analyzed using PLS-SEM version 3.0.
Contributions: This paper provides useful insights for aspiring entrepreneurs, managers, policy makers, corporate businesses, and governmental and nongovernmental organizations around the world to facilitate business success using passion and professionalism.
Originality/Value: This study adds to the corpus of information on professionalism in entrepreneurship and small business literature in Africa, which academics in developing countries generally overlook.
