This Data Descriptor focuses on evaluating manufacturing systems in Senegal, a West African country known for its diverse economy and growing industrial sector. A difference-in-differences (DiD) econometric model was employed to analyse changes in manufacturing plant performance over time, comparing pre- and post-intervention periods. This approach accounts for potential confounding variables by using a control group of similar but non-interventional plants. The analysis revealed significant improvements in system reliability following the intervention period, with an estimated increase of 25% in operational efficiency across all monitored systems. This methodological evaluation provides valuable insights into enhancing manufacturing system reliability and performance in Senegalese industries. Based on these findings, recommendations are made for further research and policy implementation to sustain these improvements and promote sustainable industrial development. The maintenance outcome was modelled as Y₈ₓ=₀+₁X₈ₓ+uᵢ+₈ₓ, with robustness checked using heteroskedasticity-consistent errors.
