PMOs frequently manage portfolios, report project/program status to higher management, develop and use standardized project management methodologies, mentor project managers, and even handle particular projects or programs that are deemed strategic.
Examples of project management
According to PMO Services Canada, Project management is the science and art of organizing the various parts of a project. The launch of a new service, a marketing campaign, or the development of a new product are examples of projects. Even a wedding requires project management.
