Influence of human capital development on employee performance in Kenya power and lighting company, Kenya

Abstract

Employee performance is a critical determinant of organizational success, impacting productivity, service delivery, and competitive advantage. High levels of employee performance are essential for organizations to meet their strategic goals, enhance operational efficiency, and remain adaptable to market demands. In Kenya Power and Lighting Company (KPLC), employee performance is closely linked to the capacity of the workforce to meet the evolving demands of the energy sector. To improve performance, KPLC recognizes the importance of human capital development (HCD), specifically employee training, career development, performance management, and knowledge management, in bridging skill gaps and optimizing workforce output. Despite the importance of these strategies, there is limited empirical research exploring the individual and joint effects of these human capital components on employee performance within utility organizations. This study investigated the influence of human capital development, specifically employee training, career development, performance management, and knowledge management, on employee performance at KPLC. Grounded in Experiential Learning Theory, Social Cognitive Career Theory, Goal-Setting Theory, and Social Exchange Theory, the research employed a descriptive cross-sectional design. The target population consisted of 1,200 employees in the Mount Kenya Region, from which a sample of 300 respondents was selected using stratified cluster sampling. Data were collected using structured questionnaires and analyzed through both descriptive and inferential statistical methods. Diagnostic tests, including normality, multicollinearity, and homoscedasticity, were conducted to ensure the robustness and validity of the regression model. The multiple regression analysis revealed an adjusted R² value of 0.797, indicating that 79.7% of the variation in employee performance was explained by the four human capital development dimensions examined. The overall model was statistically significant (F = 69.857, p < 0.001), confirming that the independent variables significantly explain variations in employee performance. Specifically, all four components of human capital development had notable positive effects on employee performance. Employee training showed a significant positive impact (β = 0.395, p = 0.000), career development (β = 0.428, p = 0.001), performance management (β = 0.512, p = 0.000), and knowledge management (β = 0.601, p = 0.000) each demonstrated strong contributions to performance enhancement. These results underscore the vital role of structured human capital development initiatives in boosting employee engagement and productivity. Notably, knowledge management exhibited the greatest influence, highlighting its role in fostering organizational learning, collaboration, and enhanced productivity. The study concludes that the strategic application of integrated human capital development initiatives significantly enhances employee performance at KPLC. The findings suggest that utility organizations should institutionalize structured training programs, career progression pathways, transparent performance management systems, and knowledge-sharing platforms to optimize workforce potential. These insights offer valuable implications for policymakers, HR practitioners, and corporate leaders seeking to improve organizational performance through effective workforce development.
