A Project Management Office (PMO) is a central organization or department within a company that is responsible for defining and maintaining project management standards, processes and governance. It typically acts as a support and guidance function for project managers and teams, helping them to plan, execute, monitor and close projects successfully. PMO may also be responsible for project portfolio management, resource management, project reporting, and risk management. The goal of a PMO is to ensure that all projects within the organization align with business objectives and are completed on time, within budget, and with the desired outcome.
