The baseline

What running the business already takes.

The part

The work that happens regardless of any plan. Almost never measured, and consistently underestimated by the people planning on top of it.

Estimated once, honestly, it changes the shape of every subsequent plan.

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.
