This study investigated the impact of e-procurement systems on decision-making processes at Hill Water. The research explored how different components of e-procurement systems, e-tendering, e-catalogue, e-invoicing and payment system influence decision-making. Employing a quantitative case study design, data was collected from 67 employees at Hill Water using questionnaires. The findings indicate a strong and statistically significant positive relationship between e-procurement systems and improved decision-making processes. A multiple linear regression model revealed that the e-procurement components collectively explain a substantial portion of the variance in decision-making (R^2 = 0.692, Adjusted R^2 = 0.687), with the model being highly significant (F (5, 61) = 28.56, p < 0.001). Individually, all tested components demonstrated significant positive relationships with decision-making: e-tendering (B = 0.35, p < 0.01, with a correlation of r = 0.72), e-catalogue (B = 0.28, p < 0.05), e-invoicing (B = 0.19, p < 0.05). These key statistical findings underscore the crucial role of a well-implemented e-procurement system in enhancing organizational decision-making. The study recommends that Hill Water continues to strategically invest in and optimize its e-procurement infrastructure to further enhance organizational efficiency and effectiveness based on these empirical result.en-USThesis
