Welcome to the Official P3O Website

The P3O guidance - aligned to the Cabinet Office's PRINCE2, MSP, and M_o_R - brings together in one place a set of principles, processes and techniques to facilitate effective portfolio, programme and project management through enablement, challenge and support structures.


The purpose of the Portfolio, Programme and Project Offices (P3O) guidance is to provide universally applicable guidance that will enable individuals and organisations to successfully establish, develop and maintain appropriate business support structures that will allow:

  • Informed senior management decision making on strategic alignment, prioritisation, risk management, optimisation of resource etc to successfully deliver their business objectives (portfolio management)
  • Identification and realisation of business outcomes and benefits via programmes
  • Successful delivery of project outputs that enable benefits within time, cost and quality restraints.
