Jason,
I'm tasked with the same thing you are, and we, too, are largely an
IBM shop, so maybe we can help each other out on this task.
The approach I'm taking is to define at a very high level what our
most common use cases are. These come down to pretty simple message
exchange patterns such as request/reply, one way, notification, etc.
Out of those patterns, request/reply is our most common, so that's
where I'll focus first.
A reference architecture must satisfy your major use cases and your
non-functional requirements, so I try to define a logical component
model that satisfies these requirements. Major architectural elements
(such as an enterprise service bus) emerge as you look harder at the
non-functionals. Once you get to a certain level of maturity with
your component model, run your use cases through the component
diagram. I'm taking an iterative approach, so I get to a certain
point, run use cases through, review that with a larger group, and
make appropriate changes.
Let me know if that's in-line with your approach. I'm interested in
other ideas.
