The floor
The level that holds when everything else is going wrong.
The part
What it is
Set deliberately below what the team can normally manage. The floor is what protects the habit in the quarter where nothing goes to plan.
A floor that has never been tested is a hope. The quarter it survives is the one that establishes 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.
