Rent a Car in Just 0, 60, 240 or 1,217 Seconds? - Comparative Usability Measurement, CUE-8

Abstract

This paper reports on the approach and results of CUE-8, the eighth in a series of Comparative Usability Evaluation studies. Fifteen experienced professional usability teams simultaneously and independently measured a baseline for the usability of the car rental website Budget.com. The CUE-8 study documented a wide difference in measurement approaches. Teams that used similar approaches often reached similar results. This paper discusses a number of common pitfalls in usability measurements. This paper also points out a number of fundamental problems in unmoderated measurement studies, which were used by 6 of the 15 participating teams.
