As I've discussed in previous posts, it's not uncommon for our Documentum customers to also use Microsoft SharePoint (and vice versa). The two products are more complementary than competing; by combining them, you can actually get a higher ROI from each. Users can benefit from SharePoint's familiar interface for team collaboration, Office integration, and social networking, while participating in wider Documentum-orchestrated business processes and protecting their documents with Documentum's pervasive governance features.
In a free Webcast on June 11, we'll explore the synergies between Documentum and SharePoint and discuss the use cases for which the two platforms work well together. We'll also demonstrate the integration technology that allows Documentum and SharePoint to easily inter-operate.
