What is P3O?
Portfolio, Programme and Project Offices (P3O®) was first published in 2008 and more recently revised and published in 2013. The guidance is accompanied by an associated certification scheme.
A P3O model provides a decision enabling/delivery support structure for all change within an organization. This may be provided through a single permanent office which may exist under several different names, for example Portfolio Office, Centre of Excellence, Enterprise or Corporate Programme Office.
