Background: Total productive maintenance (TPM) recently attracted the manufacturers and researchers of developing countries like Bangladesh because of its usefulness in waste minimization and production improvement. However, successful implementation of TPM in manufacturing industry depends on many critical factors. It is very important to know the significance level of these factors due to effective management. Purpose: This study aims to develop a critical success factors model for TPM implementation in manufacturing industries. Methodology: This research used a Delphi based analytic hierarchy process (AHP) to develop the critical success factors model for TPM implementation. Data were obtained from eight manufacturing organizations of Bangladesh. Results: The research found that the lack of managerial expertise and staff motivation are the most critical factors for TPM implementation in developing countries like Bangladesh. This research can assist the manager to understand the nature of each critical factors. Finally, a sensitivity analysis was performed to justify the robustness of the rankings of the factors.
