Definition

A project management office, also reffered to as a PMO, is a group or department within a business that defines and maintains standards for project management within a organisation. The PMO acts to standardise and introduce economies of scale and repetition in the execution of projects and programmes.

General

The PMO plays a key role in organisations because it defines and maintains the standards and processes related to effective governance of projects.  It provides the visibility needed to cancel, postpone or scale back unnecessary or less strategic projects, giving room to those that are critical to the organisation.  It also facilitates the standardisation of project management practices and provides methodologies for repeatable processes. 

The PMO also enables better resource management by allocating skills and expertise ina structured manner.  Roles and responsibilities are defined with clear routes for reporting, ensuring that all team members are aware of their role when delivering the project.
