Microsoft Office Project Portfolio Server 2007 is designed to help organizations manage and measure their corporate project portfolio. Project Portfolio Server helps your organization identify, select, manage, and deliver portfolios that align with your strategic priorities.

Project Portfolio Server integrates with Microsoft Office Project Server 2007 to provide an integrated project portfolio management solution. The bidirectional gateway enables administrators to link multiple Office Project Servers to Office Project Portfolio Server 2007, providing executives with a consolidated view of all projects within the organization. 

Within an application's lifecycle, Project Portfolio Server can enable proper selection and vetting of software projects.  Through integration with Project Server and indirectly to Team Foundation Server, Project Portfolio Server can be used to not only select the right application development projects but also to measure the success of those projects.
