Flows before screens
Five flows
- Sign in: do you have an account, and is the data valid?
- Book a doctor: is the time available?
- Pharmacy: is it the right item, and which payment method?
- AI assistant: ask a follow-up, save the answer, or go home.
- Online consultation: is there an active subscription?
One decision point, one feature
Drawing “Time available?” forced the question nobody had asked: what happens when the answer is no? The flow gave three exits, join a waiting list, pick another time or pick another doctor, and the waiting list became part of the booking flow.
A flow is cheap to change. A screen built for the happy path only is not.
