Discerning Interrelationships among the Knowledge, Competencies, and Roles of Project Managers in the Planning and Implementation of Public Sector Projects

Abstract

This study uses information gleaned from a sample of 102 public sector project managers to assess the interrelationships among project manager roles, responsibilities, and competencies in the planning and implementation stages of the project life cycle. The results of confirmatory factor analysis and structural equation modeling revealed that project managers use different subsets of their skills to influence outcomes at these two stages of the project. For example, while the project manager's organizational and technical skills tend to have some influence during the project planning stage, managerial, leadership and people skills appear to have more influence during the project implementation stage. Implications of these and our other findings for the practice of project management in public sector organizations are discussed.
