User personas help you really get who your audience is. Here’s how to weave them into your design thinking:

• Research and group: Do some user research to spot different groups. Make personas for groups with similar traits.
• Detail the personas: Flesh out these personas with details like age, habits, what they want, and what bothers them. Take "Busy Professional Sarah, 30, looking for quick wellness options," for example.
• Step into their shoes: Try to see things from the persona's point of view to grasp their needs and drives.
• Spot patterns: Look for what's common or different among the personas to spot key themes.
• Define the problem: Use what you've learned about the personas to state the problem as they see it. For Sarah, it might be "Needs a wellness app that fits her tight schedule."
