This analysis reveals significant efficiency improvements in Tanzanian manufacturing plants, suggesting targeted interventions for growth.
Manufacturing plants in Tanzania face challenges related to operational efficiency, which can impact productivity and economic growth. The study employs Bayesian hierarchical models to analyse data from Tanzanian manufacturing plants. This method allows for the incorporation of both plant-specific and industry-wide variations, providing a nuanced understanding of system efficiencies. Bayesian hierarchical modelling revealed significant efficiency improvements across different sectors in Tanzania, with some facilities showing gains exceeding 20% in operational performance. The results suggest substantial room for improvement in manufacturing sector efficiency through targeted interventions and policy support. Policy makers should prioritise investments in technology upgrades and training programmes to enhance the operational efficiencies of Tanzanian manufacturing plants. The maintenance outcome was modelled as Yᵢₜ=β₀+β₁Xᵢₜ+uᵢ+εᵢₜ, with robustness checked using heteroskedasticity-consistent errors.
