SharePoint is really a collection of capabilities. At its heart, it is a Portal that exposes information customized for a particular user. It has extended functionality to quickly build features inside this portal to enable Enterprise Content Management and Enterprise Search. It has ventured into Social Computing and Collaboration by creating shared work spaces, supporting blogs and wikis and allowing people search. With the inclusion of PerformancePoint in its licensing, it also becomes a strong Business Intelligence offering, though it will require expanded knowledge of that capability to implement. It starts to break down when pushed to work as a Business Process Management Suite or Application framework.
