Choose evaluators

Evaluators are individuals who have the expertise to perform usability inspections. Typically, they are user researchers or designers who work on the product. In reality, it's not possible to find an unbiased evaluator, because we all are humans, after all.

Regardless of evaluators' skills and experience, their opinions can still be skewed by their own biases. Another issue is that they're not typical users of the product, which means that their simulated experience isn't 100% accurate.

Companies can involve several independent evaluators to receive a more comprehensive evaluation.
