SOA can deliver strategic value to companies willing to change (part of) their enterprise, not just their IT systems! Many companies however have tried and failed delivering SOA with the promised reduced IT burden and ROI. Some companies are even treating SOA like a disease. This is not fair. SOA is a way of thinking applied to supporting tools and not a tool on itself.
I hope this collective set of topics will help companies decide whether this SOA thing is blessing or burden.
