What characteristic is least likely to be expected in usability testing?

Usability testing is primarily focused on understanding how users interact with a product or interface and identifying any issues they may encounter. The goal is to collect specific data on user experiences to inform improvements. In this context, characteristics like feedback on layout, collaborative evaluations, and individual assessments are commonly expected.

Feedback on layout is crucial as it directly relates to the user's interaction with the interface and helps identify areas for improvement. Collaborative evaluations encourage team input and can enhance the overall understanding of user experience by involving multiple perspectives. Individual assessments are integral to usability testing because one-on-one interactions allow facilitators to observe and gather detailed feedback about personal user experiences.

In contrast, group consensus is least likely to be expected in usability testing. Usability testing aims to gather specific insights from individuals rather than finding a collective agreement. This allows for a more nuanced understanding of user behavior, as different users may have varied experiences and suggestions. Focusing on group consensus could mask individual challenges and insights, which is counterproductive to the goals of usability testing.
