Hang on in there, Bob. Although we're not there yet, what you're doing
is interesting (to me) and (I anticipate) ultimately fruitful.

But, in ergo-speak, the "cognitive complexity" of the "paradigm" is
enormous. This means you no sooner bridge one mental gap when you
expose the next.

Work on cognitive complexity (as applied to computing -- it was going
on in other areas long before) began in the early 80s, with names like
Hammond, Morton, Long, Chapanis and Eason. Funded by IBM, the aim was
to replace much tedious expensive experimentation on live subjects
(the old HF way) by some sort of theoretical analysis which developers
themselves could employ. And what's the point of live testing anyway
unless you the developer can generate promising paradigms to test?

I think I can still draw a cognitive map: a tool for reducing
cognitive complexity. Unfortunately a map to fit an American can be a
bad mismatch for a Japanese, or even a Brit. Which is maybe why the
research petered out -- or is it just that I've not been following it?
Anyway there's no evidence of big developers like M$ applying it in
their main products. Apple have a long tradition of applying good
ergonomics, but even they're slackening of late.

I'll take a stab at it over the next few days if I get time. I still
haven't delivered on the task analysis, I know. It's a question of
who's kicking me hardest at any one moment.

But without a cognitive map to guide design decisions, we're fumbling
in the dark.
