"A PMO is a project management office or a program management office. PMOs define project management standards and best practices. They also create and maintain efficiencies by identifying collaboration and improvement opportunities.
Yes, I have worked with a PMO. My current company has a PMO, and there is a senior manager of organization development initiatives within their department. My manager and members of our department meet with him regularly to discuss our projects and make sure we are in alignment with other initiatives and are following the appropriate procedures for our projects. They also play a role in the approval process for projects with a budget over a certain amount."
