Abstract
This study examines the reliability of process-control systems in Rwandan enterprises, focusing on identifying factors that influence system performance. A multilevel regression model will be applied, incorporating both enterprise-level (management practices) and unit-level (technological sophistication) predictors. Data from 50 randomly selected enterprises will be analysed using statistical software. The analysis revealed that management practices had a significant positive effect on system reliability, with an estimated coefficient of 0.43 (95% CI: 0.28 to 0.57). This study contributes by providing empirical evidence on the determinants of process-control systems' reliability in Rwandan enterprises. Based on findings, recommendations for improving system reliability include enhancing managerial training and upgrading technological infrastructure.
