PMO structures and types explained
"PMO" covers very different things, from a light support function to a body that controls how every project runs. Choosing the wrong type is a common reason PMOs struggle. Here are the main types and how to pick the structure that fits.
The classic three
• Supportive - provides templates, guidance and training; low control. Good where delivery is already reasonably mature.
• Controlling - sets standards and checks compliance; medium control. Good where consistency is the problem.
• Directive - runs the projects directly through its own project managers; high control. Good where delivery capability is thin.
By scope
PMOs also differ by how much they cover: a project PMO supports a single large project; a programme PMO coordinates related projects; and a portfolio or enterprise PMO governs all change across the organisation. The wider the scope, the more strategic the role becomes.
Centralised vs federated
A centralised PMO runs everything from one team; a federated model has a small centre setting standards with delivery embedded in business units. Larger and more devolved organisations - including much of the public sector - often land on a federated model.
How to choose
Match the type to the problem and the delivery maturity. If projects are inconsistent, lean controlling; if capability is thin, lean directive; if teams are strong and just need support, lean supportive. And whatever you pick, size to fit it - start lighter than you think and tighten where it earns its place.
