A detailed and readable guide that answers the most common questions that arise when measuring the usability of websites, software or cellphones. What measures do you take? What do have users do? What questionnaires do you use? What about sample size and statistical analysis?
“Like other Sauro books, it’s extremely well written and concentrates on real world practice and questions. I would almost call this the usability practitioners field guide because it could almost fit in your pocket and join you on testing site.”
