With SharePoint residing in most organizations, it has become apparent that the reason for using it, comes down to a couple of reasons. Of course the core driver is a new platform that facilitates sharing and collaboration. However what happens is SharePoint either becomes a Business Tool or the Presentation Layer for all things in the business. I have lost count, on the number of clients that have asked to present some other system within SharePoint. So the big question is which one should SharePoint be? Business Tool or a Presentation Layer?
