I'd love to see a picture of this model... can you upload a picture to
the files section? If it's sensitive, maybe cross out the text we
should not see?
This is without a doubt an issue that I came across in my experience
as a usability manager.
Do you suggest that this work should be done in iteration 0 using the
agile methodology? This seems to be increasingly a recommendation in
a number of white papers and publications such as Scott Ambler.
However, when you say 'minimal effort' how does this translate into
time scales - is there an average that you work with in your
experience let's say 1-2 weeks?
I also appreciate, if you could forward the pdfs on the collaborative
UI review method that you mentioned in a previous message.
