Preference Testing

Research Questions
1. Why experienced users of online travel booking sites prefer one version over the other one.
2. Whether a new survey can successfully speak to participants’ perceptions of the experience and help researchers to understand the differences between the two proposed designs.
Participants

- Users who:
1) do not use the AMEX Travel site before
2) be an experienced user of online travel booking sites
Mockup A / B Design


Survey Design
The survey consists of 16 questions including demographics, warm up, and comparative (thoughts and ideas) elements. I mostly use guide principles, survey questions, and scoring formula of the System Usability Scale (SUS) Survey to create the survey
Results
- 70% of participants chose the proposed design (option B) and Average test score of option B is 74.88 (in comparison the average test score of Design A was 72.36).
- The survey average score shows that revising the site design can lead to a positive improvement in users' experiences.
