An illustration of a checklist and a magnifying glass over a group of people represents observing users. Additional dotted panels include simple icons: a laptop for requiring a product or prototype, a funnel for keeping tasks narrow in scope, speech bubbles for observation with follow-up questions, a balance scale for comparing designs or user groups, and a laptop with circular arrows for iterative development. The graphic provides a visual overview of how rapid usability testing supports improving usability."}
