There's definitely a need for enterprise SOA (governance, infrastructure, practices) but no authority to back anything official.
So in light of these restrictions, we're thinking of a two-pronged approach to assisting SOA efforts:
- Try to convince IT authorities of need for formal SOA.
- Collaboratively create SOA practice and standard recommendations that development groups can follow.
Step 1 involves building business cases, roadmap documents and other goodies that help convince those in power that it is worth spending money on SOA.
Step 2 involves documentation developed by the various IT groups building SOA around the organization. These documents include a service development lifecycle recommendation, service definition process recommendation, governance recommendation and interoperability best practices recommendation. These documents are to be developed in a collaborative fashion (think wiki) and will be the self-selecting SOA community's guide for how to develop and use services.
Step 2 certainly has challenges (who will make people follow the recommendations- answer no one), but should move the organization closer to full SOA while cutting down on the chaos. I like step 2 because it gives an answer to the "no funds paralysis" that makes some architects think that SOA is hopeless.
I'll post updates as to how these approaches end up working.
