1. Map one appointment.
Record staff skills, duration, location, required resources and preparation or travel buffers. Name the system that owns the booking.
Process
Test the availability rules before opening the calendar.
Begin with one service and realistic fictional appointments. Keep existing bookings protected while the new flow is reviewed.
2. Agree changes and exceptions.
Define closures, absence, cancellation cutoffs, rescheduling and staff overrides. Include what happens when a provider is unavailable.
3. Build a focused flow.
Connect service selection, available times, booking storage and the agreed confirmation. Review the customer journey on mobile as well as staff controls.
4. Try conflicting requests.
Test two requests for the same constrained slot, changed availability, failed payment and calendar sync delays. Verify that the stored booking and customer message agree.
5. Release and explain the fallback.
Document who maintains hours, handles exceptions and resolves failed syncs. Agree a controlled live check without contacting unrelated customers.
