We know, Bob, we know. We've heard this tune many times. The OP asked
about OOD. This is a perfect example of what it isn't.

What you are describing is bottom up, seat-of-the-pants programming
with perfunctory salutes to an unwitting user all of whom pretend they
have immunity from reality. And as long as the inmates are in charge
they're very happy subscribing to this stuff. *You mean, NO BOSSES?*

Look, OOD is about designing theoretical systems that may get
implemented based on analysis, testing, cost, and security factors.
That's rigor!

The fact that programmers sweat to bolt one whimsical idea to the next
is not rigor.

Rube Goldberg software development was not invented by XP but it is
given certification status thanks to XP. Even Rube Goldberg
contraptions are -cough- *designed*, documented, measured, and
quantified - yes, they are. And that makes them real - just as real as
real systems.
