ABSTRACT
This chapter provides an overview of the main roles and responsibilities in portfolio management, alongside the project lifecycle and in interaction with other key roles and stakeholders at different organizational hierarchical levels. Projects, programmes and portfolios all have one common goal, which is to contribute to the fulfilment of the strategic business objectives of the organization. Portfolio management plays a major role in planning and successful implementation of the strategy in order to maximize the benefits for the organization. In order to implement successful portfolio management several roles need to be established. The responsibilities and level of authority of each role need to be defined, with the objective of achieving the goals of portfolio management. The main roles in this context are as follows: the portfolio governance body; portfolio sponsor; portfolio manager; programme managers; project managers; and portfolio management office.
