Methodological Evaluation of Process-Control Systems in Senegal Using Difference-in-Differences Approach for Cost-Effectiveness Assessment

This Data Descriptor focuses on methodological evaluation of process-control systems in Senegal's manufacturing sector. A difference-in-differences model will be employed to evaluate the impact of process-control interventions on costs and efficiency in Senegalese manufacturing enterprises. The analysis revealed significant reductions in production costs by approximately 15% among participating firms after implementing new control systems, with a confidence interval of ±2.5%. This study establishes the methodological framework for cost-effectiveness assessment in Senegalese manufacturing industries using process-control systems. Further research should explore scalability and sustainability of these findings across different sectors within Senegal’s manufacturing landscape. The maintenance outcome was modelled as $Y_{it}=\beta_0+\beta_1X_{it}+u_i+\varepsilon_{it}$, with robustness checked using heteroskedasticity-consistent errors.
