Earlier this week I presented a very influential paper to our reading group: Damaged Merchandise? A Review of Experiments that Compare Usability Evaluation Methods, by Wayne Gray and Marilyn Salzman. Reading it again reminded me why it had such an impact on me first time around, and I thought I’d share my views on why I think it’s such a worthwhile read, even 11 years after it was published.
The paper critiques 5 prominent (i.e. published in prominent academic publications and subsequently cited) studies that compared different Usability Evaluation Methodologies (UEMs). It found that for each study the experimental design casts doubt over the validity of the conclusions made.
