Just like webMethods, TIBCO has a suite of products each focused on a different level of integration. Their claim to fame is as the inventors of pub/sub messaging and their core product Rendezvous. As you look at their product suite you’ll see an amazing parallel between it and the wM suite. Here are the very rough parallels at a conceptual level:
Broker -> Rendezvous, Enterprise Message Service
Integration Server -> BusinessWorks
Trading Networks -> Business Connect, Business Partner
Modeler/PRT, Workflow -> Staffware
Portal -> PortalBuilder
Manager -> BusinessFactor
Again, these are very crude comparisons since each of the vendors approach the solution space in different ways, though they each talk about BPM, BAM, SOA, ESB and such.
