PMO structure

There are numerous ways in which a Project Management Office (PMO) can be structured.

PMO Structure | Project Management Office Structure

There are 4 levels at which a PMO can operate:

  • Enterprise level – EPMO (portfolio management);
  • Division level (portfolio management and programme management);
  • Business unit level (programme management and project management);
  • Project level (project management).

Within each of these levels, the PMO structure which is set up maybe permanent, temporary, or a combination of the two.

A key point about PMOs is that there is no one-size-fits-all approach which works for all organisations. Every organisation has its own structure, culture, business goals, resources, policies and unique circumstances. When designing a suitable PMO structure, it is important to consider all these factors.

P3O model example

The P3O (Portfolio, Programme and Project Offices)[1] framework suggests an example PMO model shown on the diagram below.

London Olympics 2012 Programme Office example

The 2012 Olympics programme office was an example[2] of a successful PMO implementation. This PMO provided assurance to high-level government bodies. It also provided oversight role for the 4 main programme objectives.

Its key role was to act as a ‘critical eye’ by providing scrutiny, reviewing and reporting of performance, monitoring and measuring progress against programme delivery plans, and proactively challenging risks, issues and changes across the programme.

It used common standards for reporting performance to government and management dashboards for the governance bodies. The PMO reported to the Programme’s Senior Responsible Owner (SRO) and was empowered to challenge at the highest levels. It was mainly concerned with putting in the right framework, rather than imposing rigid standards.

The secretariat and office administration, finance and strategic communications functions were provided through separate but linked teams. This allowed the PMO to provide the ‘critical eye’ without having to worry about day-to-day operational functions.
