Subject: Re: RE: [soa-rm] new topic for discussion: shared services
Hi Mike,
Nope, I was not suggesting a rehashing of old discussions which _resolved_ definitions … just recommending that any new definitions be placed in the context of those existing definitions for clarity and completeness, esp. for those who might not have tuned in on the earlier discussions/resolutions.
“Managed Services” is a good example of my point – of course, every service (instance) should be managed (if only they all were! :), but the term is used more often to mean something like “A service that is managed by a provider on behalf of the service consumer(s), directly or indirectly” … a “Managed Service” might or might not be (but usually is) also a “Shared Service”.
A simple table of closely relevant terms that establish the overall context for “Shared Services” and “Enterprise Shared Services” would suffice in my judgment … but I won’t belabor the point further.
Avanti,
BobN

Subject: Re: [soa-rm] new topic for discussion: shared services
I'm also interested in discussing the topic of "shared services" (though think it is trivial from specification/ontology perspectives).
However, I am am afraid to open a can of worms that the spectrum of sensless but sound names (set around word 'service') are moving around (8 to 12 as Bob counted) .
We discussed some of them before, like 'Application Service', and concluded that an application even with a Web Service interface is not a service, and so on. Have we forgotten those discusstions and have to repeat them? [ “composite service” - I have published re-defined/updated Principles of Service Orientation based on RAF and RM and eliminated a priniciple that allowed one service to be composed by other services as contradicting other SO principles. Also, a “managed service” - which service should not managed? ]
In my recent practice, I led an establishment of shared business services in on of the major UK banks. I can share the lessons learnt if your are interested.
Regards,

Subject: [soa-rm] new topic for discussion: shared services
All,
The terms “shared services” or “enterprise shared services” often turn up in my world but the concepts are typically ill-defined, the criteria are nonexistent, and the ramifications have not been explored. Would this group be interested in adding this as another topic of discussion (and possibly a future document) along side our current SOA ontology work?
Note: a reasonable question is what do I mean by these terms, but I’d like to establish interest rather than just generating spam.
Thanks,
Ken
