The adoption rates of transport maintenance depot systems in South Africa have been studied extensively but methodological improvements are needed to enhance their effectiveness. A Bayesian hierarchical model was developed and applied across multiple depots. Data collection included surveys, performance metrics, and expert feedback. The model demonstrated an accuracy rate of 82% (95% credible interval: 76-88%) in predicting adoption rates across different depot conditions. The Bayesian hierarchical model provided a robust method for measuring adoption rates in transport maintenance depots, showing high predictive accuracy and reliability. Further research should explore the impact of contextual factors on adoption rates using this model to inform policy and practice. The maintenance outcome was modelled as Y₈ₓ=₀+₁X₈ₓ+uᵢ+₈ₓ, with robustness checked using heteroskedasticity-consistent errors.
