Discovery Frameworks: Deep Problem Discovery

I need to deeply understand [PROBLEM] that [PERSONA] faces.

Give me a question chain that goes from surface to root cause:

1. Surface question (what's happening)
2. Follow-up (get specifics)
3. Impact question (what does this cost)
4. Root cause (why is this happening)
5. Vision (what would solving this look like)

Make it feel like a conversation, not an interview.

Fill in anything in [brackets] or {braces} with your own details first.
