Exam Plat-UX-101 Topic 1 Question 149 Discussion

The study guide identifies A. Traits similar to customer personas as the correct criterion when recruiting users for testing.
A usability study is valuable only when the participants meaningfully represent the users for whom the feature is being designed. Customer personas summarize relevant user characteristics, behaviors, goals, needs, and task patterns. Recruiting participants with similar traits therefore makes the test findings more relevant to the intended experience.
Option B, friends and family, is convenient but does not ensure that participants share the behaviors or needs represented by the actual target audience. Their feedback could reflect personal preference rather than the experience of representative customers.
Option C narrows recruitment to the most common demographic and ability. That approach could exclude important user groups and does not necessarily correspond to the personas the solution is meant to serve. A representative study should be guided by the relevant user characteristics established through UX research rather than by selecting only the statistical majority.
The study-guide principle is therefore representative participant recruitment. Testing should be performed with people whose characteristics align with the intended users so that observed usability issues and responses are meaningful to the design team.
