Your question is Design a Usability Study. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Your team is preparing to launch a new product feature and wants to learn whether people can understand and use it without confusion. You have been asked to propose a study plan that will generate actionable feedback before a broader rollout.
How would you design a usability study for a new feature?
