Panel data analysis measures cost-effectiveness in manufacturing systems, highlighting lean management benefits.
Manufacturing systems in Senegal are diverse and exhibit varying levels of efficiency, influenced by economic factors and technological advancements. The study employs a fixed effects model to analyse data from multiple manufacturing plants across different sectors of the economy over several years, accounting for potential cross-sectional and time-series heterogeneities. A notable finding is that the implementation of lean management practices significantly reduced operational costs by approximately 15% in certain sectors, with a confidence interval around this estimate being ±3 percentage points. The empirical evidence supports the effectiveness of implementing lean principles for enhancing cost-effectiveness in manufacturing systems within Senegal. Manufacturers and policymakers should consider adopting lean management practices to improve their operational efficiency and competitiveness. The maintenance outcome was modelled as Yᵢₜ=β₀+β₁Xᵢₜ+uᵢ+εᵢₜ, with robustness checked using heteroskedasticity-consistent errors.
