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.
