To describe the elephant from yet another projection, I use a combination 
of intuitive and cognitive models derived from the linguistic space of the 
application domain.

The intuitive portion matches domain-specific language ("TPS Report") with 
a ready-to-hand skill set of noun-verb object metamodels. 

"Hmm, a report /has-a/ {title, ...}, /is-a/ {Retrievable, Readable, ...}."

The metamodel is the idea of "/has-a/" and "/is-a/", the notion of objects 
having types, attributes, and behaviors, and the toolbox containing 
polymorphism, assertions and all the panoply of design and programming skills.

Mixing in or out aspects such as functional programming is rather a mind 
twist, but really an extension of the metamodel. I use different programming 
languages, so I will slot in architecturally parallel constructs such as 
first-class functions vs. SAM interfaces to the same spot in the mental 
model.

I've got in trouble with certain managers for using skeleton Java interfaces 
to generate UML diagrams, because "it isn't time to code yet; we're doing 
diagrams". I defended my approach as being at the same level of architectural
design as diagramming, and consonant with how a programmer thinks. They let it 
go.

Begrudgingly.

But it was exactly what Patricia describes. If you think structurally, it might 
look like code - but hey, structure's structure however you describe it.

You sketch what you can see, try it as quickly as you can get a prototype up 
(hours, not days), and proceed in however fashion you proceed to fill in the 
details.

As a fillip, I correlate Java elements to UML differently from (and therefore 
superior to, by my definition :-') some. Java idiomatically, and 
controversially, exposes all attributes as accessor and mutator (getter and 
setter) methods. Some diagram 'getX()' and 'setX()' methods as methods under 
UML. Tsk. They're still attributes - 'get' and 'set' are just conventions 
for expressing their public face. Architecturally, at the level where UML 
can hope to do any good, I diagram them as attributes.

I'm not religious about it. If a paycheck is at stake I'll diagram them 
as blueberries if you like.
