Interview with Seth Gordon Information Architecture
Argus Center for Information Architecture: In a misguided effort to measure the effectiveness of an architecture, many researchers assess variables such as time on task (how long it takes a user to complete a given task) and error rate and recovery (the number of errors and how users recover). While these may be relevant in certain situations, like diffusing bombs or responding to 911 calls, I think they can be misleading when trying to measure the average user's experience on the Internet. I've traded in those tired metrics for two new ones: the frustration factor and user confidence of accuracy. (2001-07-22)
