According to analysts, the portals, CM, KM and Collaboration systems are fading, but will not disappear. They will be bundled into Smart Enterprise Suites (SES) to empower the virtual workplace inside companies and between them
This doesn't come as a surprise to me, because this is exactly the same evolution as the ERP, where we started with small systems, then new ideas and business rose and the different vendors started to specialize in different areas (like CRM, HR, Project management, etc.), but now most main ERP vendors has put all the different areas into one major buzz-word: ERP.
Companies like Microsoft, IBM, Divine and Hummingbird are all working on such systems, but Gartner Group does not expect SES to emerge until 2004.
Gartner has an ok description on the Target Functionality for Smart Enterprise Suites.
