Manufacturing industries in Senegal are facing increasing operational risks due to inadequate risk assessment methodologies. A randomized field trial was conducted across ten randomly selected manufacturing plants in Senegal. Data were collected through structured interviews and observational audits to assess the effectiveness of implemented risk management strategies. The study revealed a significant reduction (p < 0. 05) in operational risks among participating facilities, with an average improvement rate of 25% across all assessed parameters. The replication confirmed the efficacy of the original methodology and highlighted areas for further refinement to ensure broader application within Senegalese industry sectors. It is recommended that regulatory bodies in Senegal implement these findings into their risk management frameworks, alongside continuous training programmes for practitioners. The maintenance outcome was modelled as Y₈ₓ=₀+₁X₈ₓ+uᵢ+₈ₓ, with robustness checked using heteroskedasticity-consistent errors.
