The purpose of any PMO is ultimately to manage and facilitate something for better business results, whether it is projects or something else. A post at PM Majik briefly reviews the major principles by which this purpose can be achieved. For instance, implementing process (and tool) standards and consistency into the PMO framework is pivotal to make it work. A PMO must also be transparent about project reporting and right-sized to accommodate the number and scope of projects.
In a nutshell, the PMO has to make things better for everyone—stakeholders and project teams both. If the PMO introduces new friction that did not exist before, then something in the implementation of the PMO is off. So always be asking yourself, “What can I do to make things easier on people?”
