“Create a lean experiment canvas for appointment reminders. State the hypothesis that a reminder with a reschedule link reduces missed visits and last-minute calls. The audience is patients with appointments next week, excluding people who opted out of messages. The test sends a reminder three days before the visit and compares it with the current reminder. Measure missed-visit rate and reschedules, and keep the change if missed visits decline without more cancellations.”
