Manufacturing plant systems in Uganda have been implemented to enhance productivity and efficiency. Panel data analysis was conducted using a fixed effects model with robust standard errors to account for time-invariant variables. The estimated adoption rate across manufacturing plants in Uganda is approximately 60%, indicating moderate uptake of the systems. The methodological framework established can be used to assess and improve future implementation strategies. Future studies should consider longitudinal data collection for more detailed insights. manufacturing, plant systems, adoption rates, panel data, fixed effects model Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.
