Test the service from beginning to end with the minister or senior sponsor responsible for it.
Ministers and/or senior sponsors are accountable for everything produced by their teams, so they need to show them their service before it goes live.
Their assessment and the questions the assessors ask them will vary depending on their service and what it does.
To pass the alpha assessment, they need to confirm that the minister and/or senior sponsor responsible for the service will test it before it goes live.
To pass the beta assessment they need to explain how they’ll test the service with the minister and senior sponsor responsible for it from beginning to end, including any legacy or offline parts.
