SOA is certainly not the only architectural approach that your enterprise will require. But it can smooth the alignment and adoption of other into an EA framework. So rather than reinvent the wheel, organizations should consider using a well-established framework such as TOGAF to elevate and extend the value of SOA.
The Open Group’s new guide links all the moving parts (such as SOA principles, SOA governance, Reference Architectures, SOA maturity, SOA Meta-model, etc.) and I think it is a must-read for any enterprise architect using TOGAF® as their organization’s EA framework and SOA as an architectural style.
