Survey123 is a useful app, lots of companies needs eletronic forms, but for a wide survey like through the whole country, there's a challenge to convince adopters
about the Licensing model.
For example, in a survey census, the field team are, most of the times, temporary users, being it not viable to implement, since this resource is available for named users only.
1) Work on an elastic model, as SAAS, so only during the research, when there is an differential effort, the expenses will be raised; and we can adjust the prices for the volume contracted.
2) After build the form, the named user might set the form available as public, that asks for an user logon. The username/password could be stored in a new sheet, to control the access to the main form. In case of thousands users (External Selects feature).
For example, Esri could implement a temporary user repository, and implement that functionality.
On my opinion, this resource would encourage named users to have Survey123 as the main tools while think of about any Survey
