19.10Ask about identity very early
This is one of the first things I'd ask:
“What field uniquely identifies the same customer across systems?”
You want something like:
customerNumber = 752891
not:
company name
email
phone
Then ask:
“Can this identifier ever change or be reused?”
If they say:
“Usually no.”
Keep asking.
“Usually unique” is not an integration key.
