Nevin Berger, MIchael Arent, Jonathan Arnowitz, and Fred Sampson have
a new book out:
Berger, N., Arent, M., Arnowitz, J., Sampson, F. (2009) Effective
prototyping with Excel: A practical handbook for developers and
designers. Amsterdam: Morgan Kaufmann.
Excel is not often mentioned as a prototyping tool in the
UX/Interaction design community, but it can be a powerful tool for
generating active forms, wireframes with links, and medium or
high-fidelity prototypes. Using Excel for prototyping can be tricky
because you have a graphics layer and a spreadsheet layer, but this
book provides practical advice about how to make use of both the
graphics and the calculation features in Excel.
