What does a PMO do? Roles, types and responsibilities

A project management office (PMO) is the team that sets how an organisation runs its projects and keeps track of them. Depending on how much authority it has, a PMO might only offer templates and advice, or it might manage the project managers and decide how every project is run. Its job is to make projects more consistent, more visible to leadership and more likely to deliver what they promised.

This guide covers what a PMO does, the three types PMI describes, the jobs inside one, and which PMI certification fits each level of PMO work.

What is a PMO?

A PMO is a part of the organisation, not a project. It outlasts any single project and works across all of them, or across one department's projects. Some organisations also have an enterprise PMO that reports to the executive team and links projects to the organisation's strategy.

PMOs are not only for large companies. A firm running ten projects at once with no common reporting often needs the same discipline, even if its PMO is one person.

What does a PMO do?

PMO roles and responsibilities vary, but most PMOs do some of these:

• Standards: set the methods, templates and tools that projects use

• Governance: define how projects are approved, reviewed and closed, and who decides what

• Reporting: collect status from every project and give leadership one honest view

• Resources: help match people to projects and spot clashes early

• Portfolio support: help leadership decide which projects to start, pause or stop

• Coaching and training: build project management skill across the organisation

• Lessons learned: capture what worked, so the next project starts better

The three types of PMO

PMI's PMBOK Guide describes three types of PMO, depending on how much control they have over projects:

• Supportive: offers templates, training, good practice and lessons learned. Control is low; it works by being useful.

• Controlling: requires compliance, such as standard methods, templates, reports or governance reviews. Control is moderate.

• Directive: manages the projects directly, often with the project managers reporting to it. Control is high.

Many PMOs start supportive and become more controlling as leadership comes to rely on their reporting. Choose the type that fits the problem you actually have. A directive PMO in an organisation that only wanted better reports usually meets resistance.

PMO roles and jobs

Titles vary between employers, but these are common:

• PMO analyst or coordinator: keeps the reporting, schedules and documents in order

• Project manager in a PMO: runs projects to the PMO's standards

• PMO manager: runs the office day to day, sets the standards and reports to leadership

• PMO director or head of PMO: links the project portfolio to strategy and advises the executive team

The path usually runs from coordinating to running projects, then to running the office. Each step leans more on people, governance and business skills than the one before. Our guide to project management skills covers them.

A worked example: a PMO for 12 projects

Say a company runs 12 projects, each reported differently, and leadership cannot tell which ones are in trouble. A small supportive PMO might start like this:

1. List every project, with its sponsor, budget and due date, in one register.

2. Introduce a one-page status report with the same three ratings for every project: schedule, budget and risk.

3. Hold a monthly portfolio review where leadership sees all 12 projects on one page and makes decisions.

4. Set up a shared risk register, so a risk that affects several projects is seen once, not 12 times.

5. After three months, ask the project managers what helped and what was busywork, and cut the busywork.

Notice the order: visibility first, control later. A PMO earns its authority by being useful before it asks for compliance.

Do you need a PMO?

You probably need one if leadership cannot get a straight answer about project status, if projects compete for the same people without anyone deciding, if every project manager reinvents the same templates, or if projects keep starting that do not fit the strategy.

You may not need one yet if you run a few projects with experienced people who already report well. A PMO that adds forms without adding decisions will be resented, and eventually closed.

Which certification fits PMO work?

It depends on the level of the role:

• PMO analysts and project managers: the PMP. Its 2026 exam outline includes "Define and establish project governance" and "Support reporting and governance processes", which is everyday PMO work.

• Program-level PMO roles that coordinate related projects: the PgMP. See is the PgMP worth it?

• PMO heads and portfolio managers who decide which work gets funded: the PfMP.

The PfMP is PMI's portfolio credential, and PMI labels it an 8+ year credential. Every route asks for 96 months of professional business experience, plus 36 to 84 months of portfolio management experience depending on your education. A panel reviews your experience before you can sit the 170-question exam. Our guide to PgMP or PfMP after the PMP compares the two senior credentials.

Our live PfMP course runs at weekends, with panel review and application support, 35 contact hours and 1,000+ practice questions.
