You are right Alex, that Documentum, FileNet and Stellent will NOT become irrelevant. They are powerful systems that blow Sharepoint away as it relates to document management -- and ECM. Sharepoint can't compete in terms of functionality. I should be more clear in my point however. What I should have said was that while these tools feature far more robust DM and ECM than Sharepoint and are highly relevant and needed by many, many organizations, these organizations as individual, stand-alone companies are working on borrowed time. In other words, they won't exist much longer. In fact... Already, since I wrote this article, Stellent was bought by Oracle and the Stellent brand no longer exists in Oracle marketing. FileNet was purchased by IBM and that brand is mostly dead too. Documentum was purchased by ECM! So you see, all three of those companies were working on borrowed time and don't exist anymore. More of this market consolidation will continue as the big guns at IBM, Oracle and Microsoft have set their sights high and will continue to eat-up competitors.
