Usability Questions

A colleague recently asked me why I would choose to do Usability Testing over an Ethnographic Study?   I gave them several reasons for my selection to go with Usability Testing, namely it’s ability to give evaluative, quantitative, time-based information within a few weeks of project kick-off.  But what are all the reasons why one would choose Usability Testing over Ethnography? Or vice versa?

I’m pleased to see my SAP Colleagues conducting usability testing on new product enhancements. Check out this link about their work at a recent customer event!
