I have lots of legacy apps working in batch mode. Whenever one
application is going to be demised one, thing I plan to do is to look at
file transfers coming in and out of the soon to be demised application
and then decide which part of the problem is solvable via common data
storage and what part needs to be implemented like services.
A big bang approach where all business processes were analyzed would
take ages to complete.

Perhaps because in the scenario I described I'd be using services as an
strategy for application integration, but otherwise I don't see it as a
good fit for BPMN.
So I don't share the notion that BPMN is absolutely necessary in order
to perform SOA.
