On a current project, we had a requirement to associate Tasks, Documents, Links and Commentary with Scorecards and KPIs. We decided to integrate with SharePoint custom lists as it just made sense to use SharePoint content management and storage features so we didn’t have to redevelop it. Anyway, with a little research of the APIs provided by SharePoint and PerformancePoint Server Monitoring and Analytics, it is totally possible. Below are some screenshots of the solution. I’ll post the code for all of this later this month or early November if you want it. Let me know.
Click on a KPI and see a SharePoint Discussion Board associated with that KPI.
SharePoint Links associated with a KPI
SharePoint Tasks associated with a KPI
KPI Meta data from the PerformancePoint workspace
