Why does it become the bottleneck?
Because it is an appointment rather than a filing. Everything else in a renewal can be prepared in advance; the medical requires a person to physically attend at a time a centre has available.
In a busy period, or for a family of five, the calendar is the constraint and nothing else moves until the appointments are done.
- It requires physical attendance
- Appointment availability drives the timeline
- Families need multiple slots
- Everything else waits on the results
