Organizational Culture as a Determinant of Performance: Empirical Evidence from Water Sector institutions in Western Kenya

Purpose: This study examined the influence of organizational culture on organizational performance within water sector institutions in Western Kenya. Specifically, it focused on how shared values, personnel behaviors, and organizational routines shape institutional effectiveness. Methodology: Data were collected from 247 employees working in water service providers across Kakamega, Busia, Vihiga, and Bungoma counties. A combination of purposive and stratified sampling techniques was used to ensure adequate representation across different organizational levels. Findings: The results revealed that organizational culture has a weak but statistically significant positive relationship with organizational performance (r = 0.165, p < 0.05). Additionally, organizational culture showed moderate positive correlations with resource management (r = 0.505, p < 0.01) and leadership style (r = 0.487, p < 0.01). Regression analysis further indicated that organizational culture is a modest predictor of organizational performance (β = 0.165, p < 0.05). These findings imply that while culture contributes to performance, its impact is more substantial when reinforced by other strategic factors. Unique Contribution to Theory, Practice and Policy: The study extends organizational culture theory by demonstrating its contextual relevance within public water institutions in Kenya. Practically, it highlights the need for integrating cultural values into management systems and enhancing employee engagement. From a policy perspective, it shows the importance of aligning organizational culture with leadership practices and resource management strategies to improve service.
