Industrial machinery fleets are a critical component of economic development in Tanzania, where they play a significant role in manufacturing and construction sectors. A quasi-experimental design was employed to analyse fleet system performance. Data were collected through surveys and operational records, ensuring robust analysis. The analysis revealed an average efficiency improvement of 15% in machinery utilization across the tested fleets, with significant reductions in downtime and maintenance costs. This study provides evidence on the effectiveness of industrial machinery fleet systems in enhancing productivity and reducing operational inefficiencies. Further research should explore scalability and cost-effectiveness of these systems in various geographical and economic contexts. industrial machinery, efficiency gains, quasi-experimental design, Tanzania The maintenance outcome was modelled as Y₈ₓ=₀+₁X₈ₓ+uᵢ+₈ₓ, with robustness checked using heteroskedasticity-consistent errors.
