Which criteria should the designer consider when selecting users for testing?
A . Traits dissimilar to customer personas
B . Traits similar to friends and family
C . Traits similar to customer personas
D . traits of the most common demographic and ability

Answer: C

Explanation:

The designer should consider the traits similar to customer personas when selecting users for testing. Customer personas are fictional representations of the target users of a product or service, based on user research and data. Customer personas help the designer to understand the needs, goals, behaviors, and preferences of the users, as well as their pain points and challenges. Customer personas also help the designer to empathize with the users and design solutions that meet their expectations and requirements.

When selecting users for testing, the designer should aim to recruit users who match the traits of the customer personas as closely as possible. This ensures that the users who participate in the testing are representative of the actual or potential users of the product or service, and that the feedback and insights gathered from the testing are valid and reliable. Selecting users who have traits similar to customer personas also helps the designer to evaluate the usability and user experience of the product or service from the user’s perspective, and to identify and prioritize the areas for improvement.

Traits dissimilar to customer personas, traits similar to friends and family, and traits of the most common demographic and ability are not criteria that the designer should consider when selecting users for testing. These criteria can lead to biased or inaccurate results, as they do not reflect the diversity and complexity of the user population. Users who have traits dissimilar to customer personas may not have the same needs, goals, or expectations as the target users, and may provide feedback that is irrelevant or misleading. Users who have traits similar to friends and family may not be objective or honest in their feedback, and may have a different level of familiarity or expertise with the product or service than the target users. Users who have traits of the most common demographic and ability may not account for the variations and differences among the target users, and may exclude or marginalize the users who have special needs or preferences.
