Defining an architecture and applying SO principles are indeed different, though related, things.
Which architecture is being defined (where it "starts") is a matter of needs and goals. Applying SO principles does not need to "start" at the BA level, IMO. I generally disregard "SOA is failing" or "SOA is successful" types of stories and rumors. Mostly because there is not widespread consensus on what SOA means. Hard to praise or condemn an approach that is fairly ambiguous and open for interpretation (unless of course one condemns the ambiguity itself). -Rob --- In [email protected], Michael Poulin <m3pou...@...> wrote: > > Starting and applying SOA are different things.
