A Portfolio Director is a senior manager with direct oversight over the portfolio management team. A Portfolio Director is the primary liaison to other senior leaders and may have some decision-making authority for certain portfolio decisions. In this case, the Portfolio Director becomes the ultimate process owner for portfolio management. A PMO Director is the manager over a project management office (PMO). If a dedicated portfolio management team has been set up with a Portfolio Director, then the PMO Director’s primary responsibility is for managing the Project Managers (and related project-based roles). Otherwise, portfolio management responsibilities often fall within the PMO and the PMO Director oversees both project and portfolio management and is the process owner for both.
