P3M3 provides a structured best practice framework within which organizations can assess their current performance and plan for improvement when managing and delivering change. P3M3 breaks down the broad disciplines of portfolio, programme and project management into a hierarchy of Key Process Areas (KPAs). P3M3 can be used separately to focus on specific areas of the business or more generally to help organizations assess the relationship between their portfolios, programmes and projects.


The P3M3 maturity sub-models are:

  • Portfolio Management (PfM3)
  • Programme Management (PgM3)
  • Project Management (PjM3).
