Cognitive Walkthrough for the Web

I'm still laying the groundwork for the Mobile Website Usability study. Reading in the SIGCHI 2005 conference proceedings, I came across "Tool for Accurately Predicting Website Navigation Problems, Non-Problems, Problem Severity, and Effectiveness of Repairs." Written by Marilyn Hughes Blackmon, Muneo Kitajima and Peter G. Polson, the abstract states; "We conclude that CWW has high psychological validity, because CWW gives us (a) accurate measures of problem severity, (b) high success rates for repairs of identified problems (c)high hit rates and low false alarms for identifying problems, and (d) high rates fo correct rejections and low rates of misses for identifying non-problems." Reading through the first few pages of the paper, this may be a good way to weed out non-issues on the Mobile Website Usability Study. As we dig into the sites, our perception on issues may interfere with the true numbers and I'd like to keep them as "clean" as possible. Much of the data at first glance looks to cover headings and links. Will this work for actual navigation? We'll have to try it out and see.
