Types of PMO
Portfolio Management Office
The Portfolio Management Office (PfMO) gathers the information you need to check that "bright ideas" are truly aligned to strategy and have a worthwhile business case, before you sign off on the investment. It then monitors progress on all in-flight initiatives so you can intervene early enough to make a difference.
Agile Centre of Excellence
The Agile Centre of Excellence (ACE) combines PMO and Agile practices to support the whole-life idea-to-operations flow with an Agile mindset at every stage. In practice, this is often like a scaled-up version of the Product Management Office, but without the requirement for everything to be a product.
