Research challenges I ran into :

• Little academic evidence — Few papers on anonymous token queuing for small clinics, so sources were limited.
• No real clinic data — I couldn’t get wait-time datasets, so I used conservative estimates and ranges.
• Confusing terms — Different sources used different names for the same metrics (wait time, queue length).
• Privacy claims felt risky — I avoided legal promises and described design choices instead.
• Mixed audience needs — Needed both a simple pitch and a technical appendix.
• Mockups looked too finished — Labeled prototypes clearly so I didn’t overpromise features.
