Currently using PPM to do Time and Resource Management.  Also using a "thin slice" of the Project Management capabilities.  Interested in utilizing the tool's Portfolio Management capabilities.  So I would like to find out how other organizations are using PPM to do Portfolio Management.  Is PPM being used to manage near term proejcts (current projects and ones that are planned to start within the next 6 - 12 months) - sort of a tactical Portfolio Management approach?  Are you using PPM to strategically plan which projects should be done this year/next year based on completing business value/business cases and then re-prioritizing as things change - more of a strategic approch to Portfolio Management? or maybe a combination of both?
