peterme points to Task-Centered User Interface Design which has gone shareware (shareread?). The user testing stuff could be valuable, but the “Creating the Initial Design” section is notable for its defeatest and possibly Neilsonian approach:
The foundation of good interface design is INTELLIGENT
BORROWING. That is, you should be building your design on
other people’s good work rather than coming up with your own
design ideas. Borrowing is important for three distinct
reasons. First, given the level of quality of the best user
interfaces today, it’s unlikely that ideas you come up with
will be as good as the best ideas you could borrow.
OK, so we’re all borrowing, then where the hell do the original ideas come from? In the beginning, someone invented, and that gave us the good stuff that you’re borrowing. Ugh!
