The scorecard, dashboard and analytical capabilities from Office PerformancePoint Server would be consolidated into Microsoft Office SharePoint Server Enterprise and rebrand them as PerformancePoint Services for SharePoint.
I have worked on a project that comprised of SSRS, SSIS, SSAS, PPS and Sharepoint. As per my views, this news would come as a bit of shock to the projects that have relied on the stand-alone version of PPS. Although the end deliverable of M&A module of PPS is delivered/deployed on Sharepoint, but I feel that the development environment would be now integrated as a service/feature in Sharepoint.
Microsoft's move should make the total cost of using PerformancePoint lower. Formerly, to get started with PerformancePoint Server cost $50,000 -- $20,000 for the license (PDF document), another $30,000 to let users create scorecards, plus a $195 license fee for every employee using PerformancePoint. By comparison, a license for Office SharePoint Server 2007 costs $4,424, while enterprise licenses, which offer features in addition to PerformancePoint, will cost a total of $169 per employee.
Analytics (formerly ProClarity) and "scorecarding" (formerly Business Scorecard Manager) would be bundled into SharePoint Server Enterprise. The FRx, Forecaster and Management Reporter components of PPS Planning will return to the Microsoft Dynamics environment where they originated. The new offering, PerformancePoint Services for SharePoint, will run on SQLServer.
This would make Sharepoint a more integral part of MS BI Stack, but it would also require BI developers to learn more on the Sharepoint side as different technical consituents of BI stack like SSRS (Sharepoint Integrated mode), PPS(which would now be merged with Sharepoint) are tightly integrated with Sharepoint, and Sharepoint itself too has BI capabilites. I have already applied for MOSS 2007 Training !! Learning never stops for you if you are a knowledge worker on Microsoft Platform :)
