What does it take to actually stand up a working PMO, not just a logo?

What does it take to actually stand up a working PMO, not just a logo?
Four things, in order. Define the scope of authority the PMO will actually have. Secure executive sponsorship with budget and decision rights. Establish a governance framework before hiring. Recruit qualified staff against that framework, not against a job title. Most PMOs fail at step one and try to compensate at step four. The order matters.
