This document outlines how to build a project management office (PMO) and discusses key considerations. It describes conducting a current state assessment, defining a future state vision, performing a gap analysis, and developing an implementation strategy and plan. The implementation plan should identify services to be implemented in waves. Basic PMO services discussed include consolidated reporting to provide consistent project status updates across an organization. More advanced services involve training, coaching and establishing best practices. Implementing in waves allows starting with core services and expanding over time as the PMO matures.
