The subject

The pillar itself, in its agreed wording.

The part

What it is

Written narrowly enough to be recognisable. “Marketing” is not a pillar; “how small teams market without a marketing team” might be.

Held fixed. A pillar renamed every quarter accumulates nothing, because accumulation is the only mechanism a pillar has.

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.
