Talking to users, testing prototypes (paper, screen, etc.) and
analyzing their feedback teaches a designer what they don't know about
the problem at hand. To ignore these is to proceed at your own peril.

Thank you! These look like decent solutions. There's actually an

James,
Excellent points.
Nielsen argues that 5 users will discover 84% of the issues; not that the
likelihood of finding a particular issue is 84% - thus the discrepancy in
our figures (41% & 65% respectively).

The real issue is that the example I have given is that it is over
