Forrester has released the 2008 version of their Wave report on integration-centric BPM suites; you can find it on Vitria’s site here (registration required).
I won’t reproduce the chart here since that always seems to get me in trouble, but suffice it say that Software AG (the former webMethods product), IBM (various WebSphere bits), Vitria, TIBCO (ActiveMatrix), Oracle (SOA Suite; the BEA products were not evaluated due to timing relative to the acquisition), SAP (NetWeaver) and Cordys should all be very happy.
Sandy, thanks for the kind words. And yes, we at Vitria are quite pleased with our results in Forrester’s latest BPM Wave.
