Quick Definition:
Project Portfolio Management (PPM) is the centralized management of the processes, methods, and technologies used by project managers and project management offices (PMOs) to analyze and collectively manage current or proposed projects based on numerous key characteristics.
The Goal of PPM
The primary objective of PPM is to determine the optimal resource mix for delivery and to schedule activities to best achieve an organization’s operational and financial goals, while honoring constraints imposed by customers, strategic objectives, or external real-world factors.
PPM vs. Project Management
While project management is about “doing the project right,” portfolio management is about “doing the right projects.”
