In regard to the problem of creating shared linguistic domains, I would
like to share my experience with using IDEF0, a modeling technique that
has the effect of doing just that. IDEF0 is a graphic technique that has
a reader/auther cycle that over a series of iterations, creates a kind of
"delphic" consensus about a shared reality. It seems to me the process
works like this:

(1) Questions are asked, and grahic patterns with suggested vocabulary
are created.
(2) This is compared to perceived reality by independent review with
other people. The patterns and vocabulary get better.
(3) This is repeated at levels of greater detail, in a hierarchy.

The effect of this process is:
(1) The patterns created in the process become objects in a consensus
reality, created by agreement. This "reality" did not exist before the
modeling started.
(2) The model alters the world for the participants, since the perception
of the world is partially filtered through the
objects in the model.
(3) The longer people work to develop the model, the deeper the patterns
of the model are embedded in their minds. The objects in the model become
intuitively "true" representations of reality for the people involved.
(4) The vocabulary in the model becomes a shared linguistic domain, not
just because of the language, but because the set of shared perceptions
created about how the world works. The language seems to me to be
following the perceptions (originally visual), although I am not sure. It
may also be another loop that I merely percieve this way.

I have watched this process occur many times. I have seem different
groups in the same company develop different models of the same general
process concurrently, and war with each other because the process creates
groups in the same company develop different models of the same general
process concurrently, and war with each other because the process creates
a "gut feel" that their view is "true".

I apologize for not getting the subject line exactly right. I deleted the
messages I am replying to, and am guessing at the right title. Moderator,
if you could correct this and excuse it as a newbie problem, I would
appreciate it.
