As far as SOA goes the predicament of service granularity is going to haunt everybody.What level of services? Would we have elementary services, which then are composed into composite services usable by services consumer? Or lets not worry about granularity, just define the services from consumer perspective and be done with it. Oh, what about evolution of services? What abput multiple perspetives? Questions galore, no answers...
IBM fellows do talk about this and in general about maturity of SOA. They have put some material which touches upon these areas. I hope they have some answers.
Interestingly IBM's SOMA (appears to be an hybrid approach which borrows from MDA) looks most promising. But as IBM says, the whole area is so immature. For now, it might suffice to say that SOA is a journey and may talk a long time to finish it. Have patience, this is the right path but a slightly longer one.
These are my thoughts about various issues faced by an enterprise architect.
Here you will find thoughts related to enterprise architecture, TOGAF, SOA, BPM, MDA, MDD, Web 2.0 etc.
