The current focus is on the non-transactional journey
Currently we are concept testing journey 2 in the diagram below because journey 3 will lead back to the gov.uk page and journey 1 is not something we can test so specifically as we do not know how a bank or insurance company might package it.
Journey 2 is also distinct in that users can create an account without having to do a transaction. This is in contrast to Verify where you can only create an account during a transaction.
Assumptions
Big picture
Journey 1 is envisioned to have the highest volume of users signing up for a DBI facility.
Private sector will drive the highest numbers of businesses getting DBI assured.
In Journey 3 we will give them a choice around signing up for an account.
MVP is agnostic to environment as it is a back end thing
Testing
Everyone will have a personal identity (a personal bank etc) (so no need to probe in this direction so much)
Journey 3
This is the journey into government at the point of need
A likely entry point for users looking for funding
