Project portfolio management (PPM) is an increasingly employed, tool-supported process for selecting projects and managing the project portfolio with the goal of creating maximum value for the organization. Implementing PPM requires establishing governance and responsibilities, new processes for information collection; formal methods for project and portfolio evaluation; and culture change. The key component of PPM is knowing how to identify the best projects.

The benefits experienced by PPM users include cost savings; performance gains; better project information and risk management; more accountability; more consistent, efficient and transparent decision-making processes; reduced politics; and increased stakeholder confidence.
