Longitudinal usability data collection: art versus science?

In this proposal the authors describe an exciting panel for CHI 2008 on Longitudinal Usability Data Collection. Collecting usability data over time is increasingly becoming best practice in industry, but lacks "thought leadership" in the current literature -- very few articles or books exist addressing the topic. To inspire academic research and share best practices with practitioners, we propose a panel to debate some key questions that arose from the CHI 2007 SIG on the same topic.
