Boosting Coordination and Employee Motivation in Mega-Project Sustainable Performance Through Quality Relationships: The Key Role of Quality Management System

Coordination and employee motivation play vital roles in a mega-project’s sustainable performance, particularly in the construction industry. With increasing demands from stakeholders and employees in the construction sector, sustainable performance has emerged as a priority. However, the importance of quality relationships and quality management systems is often overlooked. This research addresses this gap by establishing a predictive model for sustainable performance. Data from 261 respondents in Pakistan’s construction industry were collected, and hypotheses were tested using partial least squares structural equation modeling. The results indicate that coordination and employee motivation exert a positive impact on sustainable performance. Furthermore, quality relationships partially mediate the relationship between coordination and sustainable performance and between employee motivation and sustainable performance. Additionally, quality management systems significantly moderate the relationship between coordination and sustainable performance, whereas the relationship between employee motivation and sustainable performance is insignificant. This study provides valuable insights for project coordinators, project managers, and policymakers on enhancing the stability of construction projects in emerging economies through quality relationships and quality management systems.
