I'd agree with Susan's post that your question is a big one, and she gives good advice. One specific that I'd add, is that if you are planing interview-based tests on about 10 people, then the metrics you are quoting have some use, but limited use, as they are more quantitative measures. In the interviews you'll be asking people what they think, what they do and don't understand, and why, which you can't measure with clicks or a stopwatch. * Nick Gassman - Usability and Standards Manager - http://ba.com * -------------------------------------------------------------- Tip of the Day: Use the archives to research common questions CHI-WEB: www.sigchi.org/web POSTINGS: mailto:[log in to unmask] MODERATORS: mailto:[log in to unmask] SUBSCRIPTION CHANGES & FAQ: www.sigchi.org/web/faq.html --------------------------------------------------------------
