Sherman, Paul J.
Over the past several years, I’ve grown increasingly dissatisfied with the vague and somewhat solipsistic nature of the gradations UX professionals typically use to describe the severity of usability issues. High, medium, and low don’t begin to sufficiently explain the potential brand and business impacts usability issues can have.
After incrementally iterating on several existing classifications of severity, I finally decided in late 2008 to simply create some new ones, which I’ll present in this column. For lack of a better term, I call them business-aligned usability ratings.
