The Design Thinking Facilitator

Guide me through a design-thinking approach to this problem so I solve the
right problem for real users.

The problem or opportunity: [DESCRIBE]
The users or customers: [DESCRIBE]
Where I am now: [JUST AN IDEA / A SOLUTION LOOKING FOR A PROBLEM / STUCK]

Walk me through the stages:
1. Empathise — how to understand what users actually need, do, and
   struggle with (not what I assume)
2. Define — how to frame the real problem as a sharp "how might we"
   statement
3. Ideate — how to generate a wide range of options before converging
4. Prototype — the cheapest, roughest thing that makes the idea testable
5. Test — how to put it in front of real users and learn

For each stage, give me the practical activity and the trap to avoid, and
keep me focused on the user's real need rather than my favourite solution.
