Productivity Management of Construction Companies: Investment Holdings of the Bank Keshavarzi of Iran Fund

This research investigates productivity management within the construction company, addressing the critical need for centralized and integrated systems in project-oriented organizations. The study adopted a case study approach, focusing on 15 construction companies within Tadbir Holding, with a statistical population of 80 senior managers and technical experts in Tehran. Data was collected using a questionnaire incorporating the Patterson Job Performance Questionnaire and Porter Organizational Commitment Questionnaire. Data analysis was conducted using SPSS16 software. The results show that "Organizational Effectiveness" was the highest-ranked basic factor (mean rank 5.505), while "Synergistic Utilization of Internal Resources and Capabilities" was the lowest (mean rank 5.499). Among sub-factors, "Level of implementation and adherence to a common set of values, beliefs, and norms across all construction companies within the organization" was prioritized highest (mean rank 4.92). Statistical analysis using single-sample T-tests (95% probability) supported all hypotheses, indicating that productivity management can advance goals, and construction companies influence other investment and construction holding companies. These findings underscore the importance of fostering a strong organizational culture and ensuring effective support from the holding company to enhance overall productivity within the construction sector. The findings reveal that enhancing synergy among holding subsidiaries, securing financing for construction companies through holding company capital, employing highly adaptable managers, fostering a rich and impactful organizational culture within the complex, and actively implementing these strategies can effectively manage productivity within construction companies. This, in turn, contributes to increased productivity across the entire holding system.
