Abstract
Manufacturing plants in Rwanda face various risks that can hinder their operations and productivity. A difference-in-differences (DiD) model was employed to assess the impact of implemented interventions on reducing operational risks among selected plants. The DiD model revealed a significant reduction in operational disruptions by 20% across evaluated manufacturing sites, indicating effective risk mitigation strategies. The difference-in-differences analysis demonstrated substantial benefits in managing operational risks within Rwanda's manufacturing sector. Further studies should explore the scalability and sustainability of these interventions to broader sectors.
