P3O ®* - Portfolio, Programme and Project Offices
P3O guidance was first published by the Office of Government Commerce (OGC) in 2008.
A P3O model provides a decision enabling/delivery support structure for all change within an organisation. This may be provided through a single permanent office which may exist under several different names such as Support Office, Portfolio Office, Centre of Excellence, Enterprise or Corporate Programme Office. It may otherwise be provided through a linked set of offices (portfolio office, programme offices, project offices), both permanent (enabling/supporting business objectives and consistency of delivery) and temporary (enabling/supporting specific programmes and projects), providing a mix of central and localised services.
The purpose of the Portfolio, Programme and Project Office (P3O) guidance is to provide universally applicable guidance that will enable individuals and organisations to successfully establish, develop and maintain appropriate business support structures.
