We're with Peter on this: soa as the broader concept embracing an inter-connected ecosystem;  ea as a narrower tool mostly deployed within an individual organisation.

We didn't discuss this on last week's call from my recollection, so now I'm back at my desk I wanted to add a +1 to Peter's view, notwithstanding what Chris might have to say.  
 
Chris, reading this thread, can you tell us what CST's intention/vision was when you used the tem(s). Does it fall into any of the categories Peter has suggested, or did you guys have an altogether different position on it?
 
Cheers
Colin

Hmmm,
This might become a metadiscussion around the relative merits of referring to EA or SOA, and I’m certainly sensitive to the issues of perceptions of scope of both. 
A quick insight to why, in my thinking at least, SOA > EA.
We struggled hard in the SOA-RM TC to ensure that the vision of SOA was broad and specifically not technology dependent – we argued that it was a paradigm for service delivery in a distributed, multiply owned and governed ecosystem. OTOH, perceptions of EA are precisely all-of-enterprise but still *within* an enterprise.
At the end of the day, this TC will not be the place to argue which is more appropriate (and I know that you’re not suggesting that it should, me neither), so it will be a question of getting across the importance of enterprise architecture (lower case) and the relevance of SOA (understood in its SOA-RM sense) as a paradigm
 
Cheers,
Peter
