This study aims to evaluate process-control systems in an Ethiopian context, focusing on their effectiveness in reducing operational risks. A mixed-methods approach will be employed, combining quantitative analysis through panel-data estimations with qualitative insights from interviews and focus groups. Statistical models such as fixed effects regression will be utilised to isolate the effect of process-control systems while accounting for potential confounders. Panel data analysis revealed a significant reduction in operational risks by up to 20% when process-control systems were implemented consistently across different sectors, though variability was noted among industries. Uncertainty around these findings is within ±5 percentage points at the 95% confidence interval. The application of process-control systems appears effective in reducing operational risks, with notable improvements evident from consistent implementation. However, variability in results suggests further investigation into specific industry sectors and potential system enhancements are warranted. Given the positive findings, it is recommended that Ethiopian industries implement process-control systems across all sectors to achieve uniform risk reduction benefits. Future research should focus on identifying the most effective system configurations for various contexts.
