[SPAM] Re: [soa-rm-ra] random question & Point of Action

[Danny Thornton <danny_thornton2@yahoo.com>]

I agree that analyzing real world effects is
beneficial in drawing boundary lines for your stake
holders. It is also beneficial to analyze points of
action for those real world effects.  However, this
changes my initial view of a SOA point of action being
an instance of a service involved in an interaction
that results in a change to shared state.  For
example, the point of action could be some
environmental effect.
