Usability benchmarking case study
Richard P. Martin, Scott Weiss · 2006
In spring 2004 Usable Products Company set to study the shopping, purchase, and assignment process for mobile media (wallpaper, ring tones and games for mobile phones) in the US market. A large scale (200 initial interviews followed by an additional 60) study covering 5 major US carriers and 13 handsets was conducted between 2004 and 2005 to benchmark the usability of mobile media purchase process. In this paper, we describe the goals, procedures, timeline, and results of this project with particular focus on what changes were necessary to move from a formative to a normative usability testing process.
