The definition
What puts a customer in this segment.
The part
What it is
A rule rather than a description. Someone should be able to look at a customer record and say which segment it belongs to.
Where the rule requires interpretation, it will be interpreted differently by every team using it.
The smallest level
The attributes it carries
Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
