The problem
When the calendar is full but rooms are empty, the calendar lives in three places.
The front desk writes in a book, consultants in Zalo, doctors in their heads. You find out at the hour that two customers share a bed, or a bed is free while a customer waits in the lobby.
- Reschedules by text that nobody writes down
- No view of which room or machine is free
- Cancelled customers still holding a slot
The usual way
- 1Read the message on the phone
- 2Open the calendar app, find a free slot
- 3Open Excel to look up the customer
- 4Retype name, phone, service
- 5Go back to Zalo to confirm the time
5 steps, 4 screens, easy to mistype
