This study examines the implementation of manufacturing systems in Ethiopian plants to improve yield outcomes. A difference-in-differences approach was used, employing regression analysis with robust standard errors to account for potential confounding factors. The DiD model revealed that implementing the new manufacturing systems led to a 15% increase in yield across all evaluated Ethiopian plants, though this effect varied slightly between different types of industries. The difference-in-differences analysis supported the hypothesis that the introduced manufacturing systems significantly enhanced yield outcomes in Ethiopian industrial settings. Further research should explore the scalability and cost-effectiveness of these systems across various sectors to maximise their impact on Ethiopia's economic development.
