EXERCISE 6.2: Clarifying Customer ID

I was showing examples of both complete and incomplete definitions during a recent training class, when I shared the following incomplete definition for Customer ID:

A Customer ID is the unique identifier for a Customer.

“What else can you say about Customer ID anyway?” a participant asked.

What else can you say about Customer ID (or any identifier) to add more meaning to its definition?

See the Appendix for my answers.
