The difference

How much it moved.

The part

What it is

In absolute and relative terms, with the uncertainty. A small difference on a large base can matter and a large one on a small base may not.

Compared with the cost per member, which is what turns the finding into a decision.

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.
