Imagine you’re designing a new app for a hospital. You could guess what nurses need—or you could sit down with them, ask questions, and listen carefully. That second path is what this chapter is about. We’ll explore face-to-face interviews, group workshops, and surveys—three powerful ways to get requirements straight from the people who will use the system. By the end, you’ll know how to pick the right technique, ask questions that uncover real answers, and spot the hidden biases that can sneak into your data.
