I am impressed by Jayoung's experience-based explanations! It's not only for the purpose of user testing, but also because I learned everyday tips such as how to lead a conversation more comfortably with the other person, and how to open up. It was fun. I think it would be helpful if you also taught us the mindset and key elements that are good to have at each stage, as well as quantitative criteria. It's good content for not only designers but also other departments, so I want to recommend it to company members~
