This study explores the role of Human Resource Management (HRM) in strategic business
management and its impact on developing a competitive advantage through human capital in
Nigeria. The research employs a regression analysis to examine the relationship between HRM,
strategic business management, and organizational performance in driving business success.
The results show that human capital, strategic business management practices, and
organizational performance are significant predictors of competitive advantage. Specifically,
human capital was found to have the strongest influence, followed by organizational
performance and strategic business management practices. The model explains 85% of the
variation in the dependent variable, indicating a strong fit. Multicollinearity, heteroscedasticity,
and autocorrelation were not significant concerns, and the residuals were normally distributed,
validating the robustness of the model. The study provides practical implications for
organizations in Nigeria to invest in HRM and strategic management to improve their
competitive positioning. Furthermore, the findings suggest that policy interventions aimed at
strengthening human capital and strategic management frameworks can contribute to
organizational success and economic development in emerging economies.
