An effective Project Management Office (PMO) can provide the structure to capture what works, turn lessons into repeatable practices, and disseminate those practices across projects, teams and regions.This interactive session explores how the PMO supports the development and application of The 4 P’s of Water Project Management as a practical framework for strengthening project delivery within a WCDA informed project environment. Using water-sector stories, project examples and audience participation, we will examine how a PMO helps create greater consistency in project alignment, decision-making, communication, risk awareness, learning and execution while allowing teams the flexibility required for different interest holders, projects and delivery models. A well-designed PMO can help organizations capture knowledge, reinforce effective behaviours, align project teams around common priorities and continuously improve the way projects are delivered to a high standard of care to internal and external interest holders.
