Investigating the Role of Leadership in Project Complexity: An Empirical Assessment Using the MODeST Complexity Model

This study investigates the relationship between project complexity and leadership competencies in project management. Using the MODeST model as a framework, the research quantifies project complexity and evaluates its correlation with transactional and transformational leadership styles. Data was collected via structured questionnaires targeting experienced project managers across various industries. A weighted scoring method was used to quantify complexity, followed by a bivariate correlation analysis. Results reveal that although most leadership competencies showed a positive relationship with complexity, no statistically significant correlation was found between leadership styles and project complexity. The findings challenge prevailing assumptions about the direct influence of leadership style on project success, especially in complex project environments. This suggests a need for a more flexible, context driven approach to leadership in project management. The study also highlights the limitations of current complexity guidelines and calls for future research using mixed methodologies.
