Re: multiparty (was) Fwd: Re: message routing

[Martin W Sachs <mwsachs@us.ibm.com>]

Regarding "the partners' partners":  I do not view the involvement of
partners' partners (i.e. subcontractors) as a multiparty collaboration.
Indeed, if the collaboration is between Party A and Party B, Party A should
not need to know anything about Party B's subcontractors or even whether or
not Party B is relying on subcontractors.

In my view, a multiparty collaboration is one in which Parties A, B, and C
directly interact with each other.  Yes, we need some good use cases before
proceeding.

Regards,
Marty

I can't resist...

Q: In a paper-based multiparty collaboration (e.g. normal business
operations of today and all of the days before now), who *controls*
the collaboration?

Oooh! oooh! <raises and waves hand vigorously>

Yes Horshack? <rolls eyes>

A: Nobody!

Why would or for that matter should this be ANY different in e-business?
IMO, each party in a collaboration, multiparty or otherwise, can only
*control* its own participation. It can and more than likely should
know only about the state of affairs between itself and its direct
partners, not its partner's partners.

Gee, I wonder how business gets done these days without some
great UML model in the sky telling us what to do every step of
the way...
