The date
When the goal is expected to have landed.
The part
What it is
A specific date rather than a quarter or a year, even when the precision is somewhat arbitrary. Precision is what makes lateness visible.
Recording who set it establishes who can move 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.
