The throughput
How much actually gets out in a normal month.
The part
What it is
Taken from what was published over several months rather than from what the team believes it could do.
Counted at publication, not at draft. Work finished and waiting is not throughput; it is inventory.
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.
