This document provides an overview of project portfolio management (PPM). It discusses why organizations implement PPM to align projects with business objectives, establish governance, and maximize investments. A five-step process for successful PPM is outlined, including gathering projects, setting strategic objectives, aligning projects to objectives, scoring and categorizing projects and budgets, and actively managing the portfolio. Benefits of PPM include justifying project cancellation, balancing risk, prioritizing based on strategy, and improving communication. Challenges include gaining executive buy-in, avoiding overcomplication, relying too much on software, and the time commitment required.
