Soft and Hard Factors, Total Quality Management, Performance, Construction Projects, Innovation, Fuzzy TOPSISAbstract
The present study aims to evaluate and prioritize the impact of soft and hard factors of Total Quality Management (TQM) on the performance of construction projects, with an emphasis on the role of innovation and continuous improvement in Tehran. Given the complexity and multidimensional nature of construction projects, traditional quality management approaches are no longer sufficient to meet the increasing demands of this field, necessitating the adoption of scientific, systematic, and multi-criteria decision-making methods. Accordingly, this study employs the fuzzy TOPSIS method to analyze data collected from 30 managers, engineers, and experts involved in large-scale construction projects in the metropolitan area of Tehran. The main indicators include soft factors (leadership and management, organizational culture, participation and collaboration) and hard factors (monitoring and evaluation systems, resources and equipment, standardized processes) of Total Quality Management, as well as two performance components: innovation and continuous improvement. The findings indicate that soft TQM factors have a greater impact on project performance compared to hard factors. Specifically, the “leadership and management” component ranked first with the highest weight (0.813), whereas the “resources and equipment” component was ranked last. Furthermore, the mediating role of innovation and continuous improvement enhances the effect of TQM factors on project performance. By emphasizing the importance of human, organizational, and cultural factors alongside structural and technological mechanisms, this study provides practical solutions for improving the performance of construction projects and introduces new research avenues in the field of infrastructure project quality management.
