Mark,
I wasn't there when you talked about eliminating the use of
un-encapsulated, public constants. Do you mean eliminate storing all of
the global (whether needed globally or not) constants in an interface
which all the classes inherit? If a constant is needed by more than one
class, what is the alternative? Feel free to refer me to an article or
something.
Thanks,
John

Your absolutly right.
That's why I say the the Data Processing attitude is deeply dug into
the larger culture.
The OO or DP decision is usually made before anyone knows that they
are actually making a decision.
However, you can at least put together a Simple Domain Model and
build with that.
The requirements above do push you into talking about data and
transformations, where you implemented is still (maybe) under control
of the programmer/designer.
It's best of course if you can refocus the requirements discussion
away from data fileds and transformations
and onto business problems and behavior.
That is often quite tricky given that most IT people and most business
people deep in their sub-conscious can only think about programs in
terms of non-OO, data processing concepts.
That's one reason I also talked about small improvments we can make
like eliminating the use of un-encapsulated, public constants.
It's a small thing.
But it can move us all to focusing more on Behavior and Nameing.
With any change, I encourge Baby Steps in the OO direction.
