I think it was Gartner's attempt to make the BPM field more comprehensible, as they had "Microsoft" (Sharepoint + Viso) in the same place as iGraphx and Nimbus, which made no sense. Intelligent BPM is about being able to enrich process with knowledge, forms, links to other systems (including workflow) to accomplish the things that a static drawing tool could never hope for. It may not be the end game, but it is an enormous step toward a single BPM tool that manages process in any part of the organization.
