Abstract
This study evaluates the effectiveness of process-control systems in Tanzanian maintenance environments. A quasi-experimental design was employed, including pre- and post-assessments with control and experimental groups. Process-control system performance metrics were collected over six months. Initial results indicate an average efficiency gain of 15% in the intervention group compared to a 10% increase in the control group, suggesting significant improvements in maintenance processes. The findings support the efficacy of process-control systems in enhancing operational efficiency within Tanzanian maintenance settings. Further research should focus on scalability and long-term impact, while practical implementation guidelines are recommended for adoption in similar environments. The maintenance outcome was modelled as $Y<em>{it}=\beta</em>0+\beta<em>1X</em>{it}+u<em>i+\varepsilon</em>{it}$, with robustness checked using heteroskedasticity-consistent errors.
