Had a look at the Documentum Business Process Management tools (BPS, BPM, Forms Builder, etc.) last week and they looked pretty good. I’m thinking if you are doing anything modestly serious with workflows you could really save yourself some time by essentially upgrading your workflow to the BPM toolset. And, obviously, if you are doing any sort of BPM like integrating with other apps via JMS (or an SOA) or pulling external enterprises into workflow processes, you really need it.
