Week 4 – Qualitative and Quantitative Usability Measures

This week I was trying to decide which type of testing would be appropriate on Chipotle’s website.  I started with error rate but decided after I tried to order a burrito I found frustration but not many errors.  I was at a loss of what to write.  I tried out number of clicks next but after I started researching how useful number of clicks is in a usability test I decided against it since there seemed to be opposition against it and I could not make a good case for it.  See:

I settled on testing task time.  There is a lot that can be done with the results of testing task time of users, especially to reveal where usability issues lie within the site.  I found a few encouraging articles about using this in usability tests and ways to present findings.  This was a large factor in my choice of measurement but I don;t think basing my choice off of research is ever a bad thing… isn’t that what research is for after all?
