Methodological Evaluation of Manufacturing Systems Yield Improvement in Senegalese Plants: A Randomized Field Trial

Manufacturing systems in Senegalese plants are crucial for economic development but often operate below their potential yield. A randomized controlled trial was conducted to assess the impact of process optimization techniques on yield improvements in selected plants. Key variables included plant size, sector type, and technological sophistication levels. An initial analysis suggests a significant increase (p < 0.05) in yield by 12% when implementing advanced manufacturing practices compared to baseline conditions, indicating potential for substantial economic benefits. The trial demonstrates the effectiveness of targeted process optimization strategies in enhancing manufacturing yields, highlighting the need for further replication and policy support. Public-private partnerships should be encouraged to fund and implement these yield improvement programmes, alongside capacity-building initiatives for local manufacturers. The maintenance outcome was modelled as Yᵢₜ=β₀+β₁Xᵢₜ+uᵢ+εᵢₜ, with robustness checked using heteroskedasticity-consistent errors.
