Practices, roles, and responsibilities of middle managers in program and portfolio management
a case study
As more organizations implement projects and use project management to achieve business objectives more economically, more of such organizations are also embracing program and portfolio management (PPM) to successfully manage their numerous projects. This paper examines the PPM practices of project-based organizations and the roles and responsibilities of middle-mangers working within those organizations. It discusses PPM's relationship to project governance and identifies PMI's definitions of program management and portfolio management; it describes transaction cost economics in relation to organizational governance mechanisms and outlines this investigation's two research questions: How does project type and environmental complexity determine the way organizations use PPM? What are the practices, roles, and responsibilities of both program and portfolio managers? It addresses these questions through a multi-method investigation.
