The Management of Portfolios (MoP) guidance has been developed to provide senior executives and decision-makers with an overview of portfolio management, the principles on which it is based, some of the techniques used, and how to get started and sustain progress. MoP guidance is suitable for professionals involved in a range of formal and informal portfolio management roles encompassing investment decision-making, project and programme delivery, and benefits realisation. The guidance is also valuable to those involved in the selection and delivery of business change initiatives, including members of Management Boards and Directors of Change, SROs, Portfolio, Programme, Project, Business Change and Benefits managers, as well as business case writers and project appraisers.
