A P3O® model provides the structure, governance, functions and services required for defining a balanced portfolio of
change and ensuring consistent delivery of programmes and projects across an organisation or department. It could
successfully take many forms, all of which are explored within the P3O® guidance – from a single all-encompassing
physical office to a complex model made up of a permanent Portfolio Office supported by permanent hubs and
temporary Programme/Project Offices.
P3O® is aligned to PRINCE2®, MSP®, and M_o_R® and brings together a set of principles, processes and techniques to help deliver projects or programmes within an organisation or department.
