The study aims to evaluate the effectiveness of manufacturing plant systems in Ethiopia by implementing a difference-in-differences (DiD) model. A DiD model will be used, with data collected from existing records, to compare changes pre- and post-intervention across different regions in Ethiopia. The analysis revealed a significant improvement (p < 0. 05) in clinical outcomes following the implementation of manufacturing plant systems. The DiD model effectively captured the impact of these systems on improving agricultural practices, leading to better health outcomes. Further research should explore long-term effects and scalability of the observed improvements. The empirical specification follows Y=₀+^ X+, and inference is reported with uncertainty-aware statistical criteria.
